GENERAL INSTRUCTIONS
Give your engine every chance to perform properly. If you become familiar with the operating requirements
it will give you long dependable service. Check the alignment of the engine to the propeller shaft after the
boat is first placed in the water. If you are in doubt how to proceed, write the factory for special service
bulletin.
Add the necessary lubricating oil to the engine. The quantity is dependent upon the angle of installation and
whether your engine is a direct or reduction drive model. Fill the oil base with 4 to 5 quarts of good grade
SAE 30 detergent oil or until the dipstick shows full. The dipstick is located just forward of the water pump
on the reverse gear housing. Check the oil level after the engine has been operated for a short time.
Check choke control to make sure choke valve fully closes. Then push choke back to normal position and
make sure choke butterfly in carburetor fully opens. Check throttle control to make sure it provides for full
movement of the throttle lever from idling position to fully open position.
Reversing gear controls must allow the clutch to lock in forward position and also into reverse position.
Restricted or partial engagement will cause undue wear. Reversing gears and reduction gears are lubricated
by the engine oiling system. Fuel like must be connected to fuel pump located just forward of reversing gear
on carburetor side of the engine. A hand primer is provided to fill the fuel bowl for initial start. Use 5/16"
copper tubing for fuel line.
An unrestricted water supply must be provided. Use a ½" through hull fitting with scoop forward. Locate
scoop where it will have a supply of water at all times regardless of running position or rough seas. Water
pump has 3/8" suction and manifold has 3/8" water outlet. Use non-collapsable hose for suction side.
