Inspect the Throttle and Shift Cables for
Kinks, Wear and Interference (RPT-1 Only)
Because this process should be completed while the en-
gine is cool and cannot cause burns to your skin, we recommend
you do this before starting your boat.
Step 1:
Ensure the engine is OFF and the engine safety starting
switch disconnected. Be certain that the throttle/shift con-
trol lever is in neutral.
Step 2:
Open the engine compartment and locate the throttle and
shift cables. Follow each cable back under the fl oorboards
and feel for any kinks and wear on the outer jacket. Any
sign of cable damage is cause for replacement. See your
MasterCraft dealer.
Check the Impeller
If the engine has shown evidence of overheating during the
previous outing or if overheating occurs during an outing, checking
the impeller is imperative!
Because this process should be completed while the engine is cool and can-
not cause burns to your skin, we recommend you do this before starting your boat. If
checking during an outing, allow the engine to cool somewhat before checking and
be very careful to avoid burns from contact with hot engine parts. If the boat is in the
water during the check, be sure to close the shut-off valve! Failure to do so could result
in excessive water intake that could potentially sink the boat!
Step 1:
Ensure the engine is OFF and the engine safety starting switch discon-
nected. Be certain that the throttle/shift control lever is in neutral. Open
the engine compartment and locate the raw water impeller housing.
Step 2:
Disconnect the intake and outfl ow hoses on the raw water impeller hous-
ing to check for debris. Reconnect.
Step 3:
Remove the screws on the impeller cover and very carefully break the gasket
seal. Because a good seal is very important to avoid potentially serious leaks
while the engine is in operation, it is advisable to have some new gaskets in
the boat’s glovebox for such occasions. If even a slight gap exists, you may
experience problems in the future, so replacing the gasket is a better idea
than taking any chances with an old one. Also, leaving any portion of the old
gasket on the housing or cover can impede good contact.
Ignoring elevated temperatures on a temperature gauge or any other evidence of the en-
gine operating at temperatures above recommended levels can result in serious damage to
the engine. Any resulting damage will not be covered by, and may void, your warranty!
Step 4:
Inspect the inside of the impeller housing. The paddle-wheel should ap-
pear as it does in the accompanying photo. If any rubber extrusions on
the end of the arm appear frayed or worn, it should be replaced. If there
is not a slight bend to the paddle-wheel arms, replace it. Debris entering
the impeller will inevitably damage it; but it serves its purpose in keeping
debris out of much more expensive internal engine parts.
