C90 Owners Manual
Shore Power Disconnect
Switch Off Breaker First
Disconnect at Boat
Never leave hot (breaker on ) a
loose cord on dock could
shock swimmers If it was to
drop in water.
Battery Switches Normally On
In Engine Room
The C90 has three main battery switches ,
House On/Off ,Engine On /Off, and
Emergency Parallel. The normal operation
position is to leave both Engine and House
switches in the On Position, Emergency
Parallel is Off.
Emergency parallel is rarely used, the boat
has a Blue Sea’s Voltage Sensitive relay
(black box near switches) it disconnects
the House Batteries from the Start Battery.
When the voltage on the Start Battery
drops below 12.7 volts it disconnects, once
the charging system has brought the Start
Battery back up to 12.7 volts it reconnects
to the house battery bank.
The Batteries have three charge sources,
First, 2 ProMariner Chargers (8A for Start
Battery and 20A for House Battery) Shore
Power is connected and AC Breakers at
dash are switched on. Second, two 80W
Solar Chargers (10A) while anchoredautomatic, Third is a 125A engine driven
Alternator.
Thruster Battery Switches, These are
mounted below the main battery
switches and are normally on. These
must be switched off when
swimmers are in the water or for
service. The thrusters are very
powerful and will suck objects in the
water toward them. Do not operate
Thruster for more that 30 seconds at
one time or motor may over heat.
Fuel System – Filters -
Priming
The C90 fuel system includes two filters and a electric switching valve at the dash. In
normal operation there is no owner/operator activity other than to inspect the Raycor
Filters clear glass bowel for water (clear liquid) and drain in to cup through petcock at
bottom if present. If the boat has set unused for several days the primer plunger on the
white Cummins filter housing should be pressed 8-10 times or until it gets hard, this
speeds crank/starting. This plunger will also be needed to prime should you run out of
fuel. Raycore uses a 10 Micron 500ser diesel filter.
Fuel Tank Switch is located to the left
side of dash. Its is labeled Main and
Aux, Main is the engine side tank, Aux
is the port tank. Depress toggle for tank
desired. You typically will run on one
tank for 3 hrs then switch so tanks drop
equally while underway. Each tank is
40 gallons approximately 36 is usable.
With full fuel at 14Kts you should have
approximately 16 Hrs running time.
This switch also swaps the engines fuel
return lines at the same time.
Full Time Power Breaker
Always On 12V power
Fuse is just inside engine
room door. Its important
to leave this on except
for service as it supplies
power to the boats 6
automatic bilge pumps
and other devices that
need power to save
memory settings. It is
not affected by battery
switch position. If Fuse is
Burned Out, there is no
bilge pump protection
from leaks.
Engine room inside wall
Engine Oil
Transmission Oil
The Cummins QSD 2.0 liter engine uses
premium 15-40 oil. It’s best to check oils
prior to use. Be carful not to spill or
overfill. Change oil and filter when new at
50 hrs then every 100 hrs after.
The Twin Disk Transmission uses 30 wt motor oil for its gear lubrication and to
engage its clutch. Check oil engine warm/off within 2-3 minutes of shut down. If the
oil is low the clutch will drop out and the boat will stop-find leak-refill. To top off,
it’s easiest to fill through the dip stick opening with supplied funnel check frequently
while filling as overfilling can damage the transmission. Change after 50 Hrs and
then every 100 hrs, clean wire mesh filter.
Voltage Sensitive Relay
This Blue Seas Systems
unit separates the house
batteries from the start
batteries automatically
when the house voltage
is bellow 12.7 volts. No
user activity is required.
Battery Chargers
These ProMariner automatic chargers
are wired to come on when the boats
shore power is connected and the A/C
breakers at the dash are switched on. The
chargers are 4 stage smart units that
charge aggressively if the battery is low
and then ramp down as it fills. They
then drop out completely when full and
then do a small topping charge weekly.
The design greatly extends battery life
and over charging and subsequent
battery damage. Check battery water
levels monthly ,lower water levels/
exposed plates will damage the batteries
lead plates requiring replacement.
Engine Room Fwd Wall
Engine Room Inside wall
Note: Chargers will only charge if
they see voltage. If batteries have
been run dead flat you will need
to use Emergency Parallel Switch,
charge for 10-15 minutes to charge
batteries enough for Charger to
see voltage.
Sea Water Ball Valves
There are two raw water valves on the boat both in the Starboard
Lazarette (inside hull side fwd). The smaller one ½” is for the head
and the aft deck wash down. The larger one 1.5” is for the engine
cooling water.
½ Inch raw water valve is run typically at 45 degrees to reduce its pressure
while underway and stop head overflow. These valves are typically left on
as running the boat with valves closed will damage the engine and
impellers.
Raw Water Valve OFF
Raw Water Valve On, 45 degrees
Engine Cooling Water Ball Valve Off Engine Cooling Water ON
Be sure to close valve when cleaning the raw water strainer

Rudder packing should be retightened/checked with each oil
change.
Drip-Less shaft seal oil reservoir,
keep ½ full with ATF type
transmission fluid (automotive type).
If it is using fluid it is very likely time
to change the three oil seals on the
prop shaft. Boat must be out of water
to do this service. Oil will
discolor/darken some with use.
Propane Tank Storage and
Operation
Tip out Bin on early Boats/New boats
have box in Port Cockpit storage locker.
Note: Locker is plumbed with a hose to a
through hull overboard so a gas leak
would not inter the boat. If you ever smell
gas stop-turn off valve and open boat to
clear fumes. Find leak.
To use, make sure hose connection
is tight, open valve, gauge will show
aprox 90 Psi. If you hear a hissing or
smell gas turn valve off ,check
connections. 15 pound tank will
typically last 2+ weeks.
Electric shut off valve only comes on if gas
controller by sink is on and sniffer smells no
gas.
Re-Installing gas box lid is easier if tip out
bin is part way closed. The tank must be
centered in compartment to latch lid in
place.
Port Lazarette Equipment
6 Gallon Seaward Hot water heater SS.
Runs on 120 V while at dock. Note it
draws 2000 watts so you will not be able
to run large additional loads while water
heater is on. Switch its breaker on only
when hot water is needed. While
cruising the engines hot water is
plumbed through the heater to heat
water.
28 gallon holding tank (black water) This
tank as are both water tanks are equipped
with a density sensor gauge system located
to right side of dash, press right hand button
to check holding tank level. If tank is full the
head will not flush. You must be 3 miles off
shore and in a area with current that will
flush to use the macerator switch at dash.
Note :shut boat off to hear change in tone
when tank is empty, running pump dry will
damage its rubber impellers. The tank can
also be emptied at a pump out station using
the fitting near the transom door. The tank
includes two dip tubes so there is no Y-
Valve to switch.
Pressure Water Pump and
Strainer: The C90 has two water
tanks (24 gallons port side and 26
gallons Starboard side) each has a
dedicated pump. The fresh water
pump switch is located on the
dashes lower DC switch panel.
Two tanks are provide so owners
can use water to trim the boat port
to starboard if needed. It like fuel is
a heavy cargo, top off only if you
need it. Water Tanks must be
drained and system primed with
RV antifreeze during winter
Getting Ready To Go
Stow fenders and dock lines in aft
compartment
Fill Water tanks as needed (port
and starboard) Cockpit fwd walls.
Be sure water is good ,taste it! Ask
fellow boaters. During long
inactive periods ad a little chlorine
to keep fresh.
Switch on Engine Blower, a cool engine is
more efficient.
Switch on Refrigerator, lower left DC panel.
Note: Switch Fuses are
behind cover plate.
Propane Control - Sniffer
The propane control unit is just fwd
of the sink. This units power may be
switched at the dash on early
models. When stove is not in use tap
the control button and turn the gas
off .
Green light When Power is on but
unit is off
Gas is on when the green Light is ON.
AC / DC Panels
DC Panel: This panel is fed from the house
batteries . It includes both voltage (pressure
gauge) and Amp gauge (volume) to manage
your power during the day, reducing amps
used is most important to extending battery
life. While boating turn all the breakers on
as shown. The small silver toggle switch
will show battery voltage engine (left #1)
and House (#2 center), #3 is not connected
as we have only two battery banks. These
breakers then feed both dash DC switches
panels and the fuse blocks for electronics
and pumps. A DC shunt is standard for the
amp meter.
AC Distribution Panel: This panel is fed
from the 30 Amp shore power
connection. Typically, all the breakers
but the hot water heater are left on
energizing the boats outlets. If you see
the red reverse polarity light lit (2nd bulb
down) see your dock master before
continuing some boat systems could be
damaged. Turn on hot water only when
needed. Both panels are Blue seas
systems premium panels.
Tank Gauges
Solar Panel Control
To read tank level:
Left Gauge = Left Water Tank
Right Gauge = Right Water Tank
Center Gauge = Poo Tank
Solar Panel Charge Controller: The Solar
Boost 2000 is a premium charge controller
that helps capture all the suns peak mid day
energy. The unit is automatic and requires
no operator input as the battery's become
fully charged it automatically ramps down its
charge so batteries are not over charged. It
also automatically shuts down if it sense
another charge source (engine or battery
chargers) The slide switch is useful to see
battery banks volts and current input. Note:
If it seems not to be charging while out, the
batteries maybe full or the Kayaks are
blocking the sun. If batteries are low and the
sun is bright the unit will put out up 11
amps.
Getting Started
Thrusters-Radio-Wipers
Thrusters: these Side Power units are
very handy while docking. Once battery
switches are on depress both ON buttons
at the same time, green light will come on.
Now the joy sticks are ready press bow
stick left boat goes left. Use in 20-30
second bursts never more than 3 minuets
of use to keep motors cool. Be certain no
one is in water near boat the thrusters
work like vacuum cleaner sucking from
a large area. Unit shuts off automatically
after 3 minuets of inactivity. A wireless
remote is available for solo docking.
Icom VHF Radio. To turn on rotate top
right knob, most conversations with other
boaters will be on low power, use Ch 16 only
for hailing ,then switch to 72 or 68, weather
also available by pushing WX button. Lower
Knob is squelch use it to turn down
background static.
Wiper Motor –Washer Control, These
are on left side of dash, two speed push
to wash, Wash tank is in back corner of
storage bin behind refrigerator under
helm seat you will have to remove safety
gear for access. Rain – X works great on
front and side windows to aid in
visibility
Getting Started
Engine and Safety Gear
STARTING ENGINE: Once batteries and
blower are on you can start, engine (starter
will time-out after 20 seconds), switch off-re
crank. If motor does not start open engine
room door and push primer plunger on white
fuel filter until hard, then restart. Important
you must warm engine up slowly over 10-15
minuets at RPMs under 2,000 prior to
running at cruise RPM Do not go above 2,000
Rpm until motor has reached 176 degrees. 80%
of engine wear is while motor is cold.
Engine Computer: This is a very useful
instrument. Toggling the propeller
button shuttles you to a variety of data.
It’s fine to push the boat and horizon
button for additional information. Oil
pressure while running will be about 90
Psi, water temperature will be about
176-180. If you hear a horn or beeping
while underway you must stop and
determine the cause. Engine manuals
are under helm seat in blue bag.
Safety Gear Storagemanuals
DC Panel Layout
Pumps Panel: This panel controls the
boats bilge pumps and shower sump
pump. Most of these are automatic but
these switches allow you to turn each of
the 6 pumps for each water tight
compartment on manually. Other than
fresh water these switches are normally in
the off position . This panel is fed from the
pumps breaker on the DC main panel. The
automatic portion of the bilge pumps is
not affected by this panel. Note: The
engine room has a 7th pump (1100GPH
emergency pump) this pump is wired to a
very loud horn behind the dash. Should
you loose an engine hose and begin to fill
the engine room this pump and horn will
come on automatically.
Ships Systems Panel: This
panel includes navigation lights,
blower and many other ship
systems. It is also fed from the
main DC panel breaker. At dash
center. These panels have separate
automotive blade fuses under the
plastic snap cover ranging from 520 amps. If a fuse has blown
determine cause possibly debris in
pump ,shorted wire . Fix then
replace fuse. To access fuses
careful ly pop grey cover off with
tape wrapped dinner knife or flat
blade screw driver-pull rubber
gasket over fuses and replace fuse.
Trim Tabs
Lenco Electronic
The C90 is equipped with large trim tabs. This tabs are primarily
used to trim the boat for maximum efficiency and comfort while
cruising. Due to their size and positioning, they can lift a great
deal while creating very limited drag. Typically after setting for
a given throttle RPM you will level and trim down to find the
maximum speed for that RPM. If the seas are choppy you may
find that less trim is a softer ride and dryer. Use your discretion.
I find in 0-12” seas full tabs is often most efficient and a good
ride. In 12-24” seas you will need to reduce tabs to 2/3 or less
and let the bow float through the seas. In larger seas you may
find no tab is best. Please note your best ride in heavy seas
will often be at 14-17Kts. If the boats bouncing or thumping try
something different.
Zero Tabs: Used for large seas 14-20 Kts
½ Tabs used in 2-3ft
seas 14-20 Kts
Full Tabs used in 0-1 ft Seas 14-17 Kts
Note: Retract tabs when not in use to protect
actuator shaft from marine growth – barnacles.
½ Tabs used in 2-3ft
seas 14-20 Kts
Shower Sprayer - Curtain
First mixer is set to temp, The sink wand lifts
to hanger near door, curtain from shelf behind
door is snapped into ceiling buttons, auto
sump pump under head evacuates water. Dry
door and shower area when done. Door can
be left open or closed when showering. Note:
Boat showers are recommended to conserve
water. IE get wet, turn off, soap up, rinse off.
Sprayer has three positions, Off, On
with button, On full time.
