. Support bracket for front power take-off
2. Steel bed frame (U-member or L-member,
thickness 0.47–0.6" = 2-5 mm)
3. Front mounting bracket (about 0" = 250 mm high)
4. Inspection covers
5. Sheet steel shims (about 0.4" = 0 mm thick)
6. Rear mounting brackets (about 0" = 250 mm high)
7. Adjustment bolts (4 pcs) for engine heightwise position. To be
removed after completed installation
8. Bolt to adjust engine lateral position
Rigid mounting
Rigid mounting is often used for commercial service
and heavy hulls. The vibration of the drive package is
not particularly noticeable with a large hull.
It is very important that the bed is level where the
engine mounts rest since otherwise there is a risk of
building tensions into the suspension joint.
With rigid mounting, the engine mounts are bolted
to the engine bed with 0 mm (0.4") thick shims.
The shims need to be milled to the correct size in
conjunction with the final alignment together with the
propeller shaft.

An approved type of moulding compound (e.g.
Shockfast) can be used instead of shims, but only
when the engine has the correct alignment.
A flexible shaft coupling can be used to absorb
changes that may occur in the alignment of the en-
gine / propeller shaft as a result of deformation of the
hull structure.
