your engines and ensure water does not enter the air
intakes. Water in the air intakes may go directly to
the cylinders, resulting in rust and possibly internal
engine damage.
IMPORTANT: The engine manual supplied by the manu-
facturer includes complete and detailed information about
operating and maintaining your boat’s engines. Be sure to
read it. Do not start or operate the boat’s engines until you
have done so. The life and performance you receive from
your engines depends greatly on the way you care for them.
IMPORTANT: Engines are not warranted by Marlow-Mainship.
Engine warranties are provided by the engine manufacturer.
11.1.4 Engine Mounts
The engine mounts installed in your boat (Fig. 11.4 sail-
drive mount) are designed by the engine manufacturer
for your specific engine. These mounts affix the engines
to the boat and, depending on your engine model, are
adjustable vertically and/or horizontally for proper align-
ment. Vertical alignment is conducted by loosening or
tightening the stud nut; horizontal alignment is conducted
by sliding the stud side to side through the notches in
the mounts.
Figure 11.4
IMPORTANT: It is advisable to spray a protective coating on the
studs to prevent corrosion.
The engine mounts also contain isolators which serve to
isolate the engine from the boat stringers or supports to
dampen vibration, noise and other undesirable effects
from engines. For more information about the engine
mounts see the engine manufacturer’s OEM manual and
the Underwater Gear chapter in this manual.
