Select a mounting location in accordance with the guidelines in the IM1000 Instal­lation Manual (supplied with the generator set). The generator set must typically be
mounted on a rigid, flat surface above a strong structure, such as the vessel’s string­ers, to minimize vibration transference to the hull. CAUTION: THE BASEBOARD

IS A NON-STRUCTURAL MATERIAL AND MUST BE FULLY SUPPORTED TO
MINIMIZE FLEX.

Note that the generator set is designed for single side service. When viewed from

Install the base board (item 1) in the vessel in as near a level attitude as possible.
Observe the arrow symbol on the board’s topside surface. This indicates the top and
forward end orientation of the genset / soundshield. Make sure arrow is correctly
positioned or the unit will not mount correctly within the shield.

Install toe bracket (item 21) to each corner of the base board with screws (item 20)
into pre-drilled holes. See figure 1.

Note that there are pre-drilled “through” holes on each side of the baseboard. Use
these holes as guides to drill into the supporting substructure for through-bolting.

Place the generator set onto the baseboard, lining up the thru-holes with the mount­ing holes in the genset base frame. Use 3/8” or 9 mm bolts of appropriate length to
secure the genset and baseboard to the underlying structure.
