ECTION
Marine reverse gears are hydraulically operated,
thereby making it imperative to periodically maintain
and check oil level. If the correct oil level is not
maintained, slippage occurs, causing damage to
the clutch plates. Too much oil will cause foaming
and erratic clutch operation. For additional
information see the Engine Operator's Manual.

XHAUST
The exhaust system on Sea Ray
inboard engines is designed so that water from the
raw water cooling system enters the exhaust
system through elbows (engine side) where water
and exhaust are mixed. Water and exhaust are then
pumped through the mufflers and then overboard
through the exhaust outlet. Make sure water is
flowing from the exhaust outlets while the
engines are operating. Prior to every boat use,
examine the exhaust system fittings to ensure
tightness.
A drain plug is located on each bypass muffler.
When servicing or winterizing, remove the plug to
drain the water out of each muffler. Replace the plug
after all water has drained from the muffler.

EMOVAL
Should the removal of an engine become necessary,
®
see your Sea Ray
service
representative
manufacturer. The following is only a generalized
procedure to follow.
Shut off the fuel lines and close the engine seacocks.
Remove all electrical wires, fuel lines and raw water
intake hoses from the engine. Unbolt the engine
coupling from the shaft coupling and slide the shaft
and coupling back from the engine. Detach both
throttle and shift connections. Cap off hoses to avoid
hydraulic fluid loss from steering system. Do not bend
or twist the hoses, as damage may result. Remove
oil exchanger, drain hoses and plug. Remove the
mounting bolts for the engine and lift the engine out,
leaving the mounts bolted to the stringer caps.
To reinstall, reverse the above procedure. Check
the coupling and shaft alignments, as well as water
hoses and wiring connections. Also check for fuel
and exhaust leaks and make sure seacocks are
open before starting engines.

IBRATION
Some vibration is to be expected in your boat
because of the action of the engines and the propeller.
But excessive vibration indicates conditions which
must be promptly corrected to avoid damage.

CTION
Weeds, ropes, fishing lines or nets can become
wrapped around the propeller and/or shaft, causing
vibration and loss of speed. Always stop and then
reverse the propeller after going through a weedy
area to unwrap and clear away any weeds which
may have accumulated. Although reversing will
sometimes help to unwrap lines and nets, they are
difficult to remove without hauling the boat.
