may be needed. It is better to flush water from one end of the cooler and then
from the other end. This should flush out any foreign particulates.
NOTE: A properly mounted serpentine belt should have a
smallamount of“play.”Withoutasmall amountofplay,the beltwillwear outwell
earlier than should be expected. Too much play will allow the belt to come off the pul-
leysystem.Pressyourthumbagainstthebeltatseverallocationsalongtheserpentine
route.Thebeltshouldgivenomoreorlessthan1/8”to1/4”.Whenthebeltisoff,at-
tention should also be given to the quality of wear of the grooves on the underside of
the belt where it makes contact with the pulleys. If you are unsure of the wear pattern,
check against a new belt. If there is any uncertainty, seek assistance from your authorized
ILMOR dealer. If the belt is too loose and comes off or too tight and wears through, it
will cause the electrical system to malfunction. This could occur during an outing and
strand the boaters. Therefore, take this maintenance function very seriously.
• Theserpentinebeltislocatedonthefrontoftheengine,exceptinV-drive
boats where it will be at the back due to the manner in which the engine is
mounted in the boat.

as shown, and use a 15mm socket to rotate the tensioner to its maximum travel. This
should allow enough slack to slide the belt over the smooth, water pump pulley.
