OIL FILTER
NOTE:
Ensure the old filter gasket is removed prior to installing the new filter.
GM Powertrain
based Kodiak Marine engines use an AC Delco (or equivalent) oil filter as
original equipment. An equivalent oil filter must be used when servicing the engine (see Engine
Quick Reference on page 22 for the recommended oil filter for your engine).
The filter protects your engine from harmful, abrasive, or sludgy particles without blocking the
flow of oil to vital engine parts.
To replace the filter, use a proper filter wrench to remove the filter. Clean the filter-mounting
base and lightly coat the gasket surface of the new filter with engine oil. Hand tighten the filter
until the gasket contacts the base, then tighten another ½ turn. Fill the engine with the correct
amount of oil then run the engine to check for oil leaks at the drain plug and filter gasket.
Tighten as necessary to stop any oil leakage.
FLAME ARRESTOR
The purpose of the flame arrestor is to contain any possible flame that gets into the intake
manifold due to an engine failure, but it serves other purposes as well.
CAUTION:
Service the flame arrestor more frequently under severely dusty or dirty conditions.
Your flame arrestor filters air entering the engine induction system and acts as a silencer. Air
that contains dirt and grit produces an abrasive fuel mixture and can cause severe damage to
the cylinder walls and piston rings. Damage to the cylinder walls and piston rings will cause
high oil consumption and short engine life. A restricted or dirty flame arrestor can cause a low
power situation. Therefore, it is extremely important that the flame arrestor be serviced at the
recommended intervals.
1. Remove all dust and foreign matter from flame arrestor
2. Clean screen by washing with solvent.
3. Blow dry or allow to fully drip dry prior to reinstallation
Make sure the flame arrestor is seated properly on the throttle body when reinstalled.
Overtightening the hose or band clamp that attaches the flame arrestor to the throttle body can
cause the throttle to bind. Do not operate the engine without a flame arrestor.
