Owner`s manual

Note: Access to the transmission uid lters is somewhat difcult in the conned
space in some models. Nonetheless, this maintenance is vital to long, trouble-free
use of the transmission. That is why it is recommended that this service be performed
by an authorized ILMOR dealer.
ILMOR recommends that the ame arrestor be inspected
and cleaned or replaced every 100 hours or annually, whichever comes first. Ideally,
this should be done at the beginning of the boating season. During storage, material
may collect inside the flame arrestor housing, whether airborne or left by
small creatures.
It is extremely important to take care that while removing, replacing and while
the flame arrestor is off the engine absolutely nothing foreign enters the engine
through the area normally covered by the flame arrestor. Any materials entering
can cause damage to your engine and will void the warranty.
Because this process should be completed while the engine is cool (in order to avoid burns),
it is recommended that this check be completed prior to starting the engine.

The purpose of the flame arrestor is to contain any backfire that may occur
during engine operation. This was a much bigger issue in older, carbureted en-
gines. It is uncommon in electronic, fuel-injected engines, but it is possible and
must be addressed.
The air filter for the MV8 engine is 94PE01163.
