What is it? I've seen it mentioned in several places. Is it something I should do on my M-18? I understand that the stock belt will not fit with this mod.
Nope. It's for the OEM alternator, too.The bracket that runs from the engine block to the top alternator that is also an adjusting bracket, needs to be modified, or replaced when using a different alternator, as the new one is usually a different size and the stock bracket can't be used.
Just buy a slightly longer belt. Once you figure out the right length, buy two more and you'll be fine for six years or more.What is it? I've seen it mentioned in several places. Is it something I should do on my M-18? I understand that the stock belt will not fit with this mod.
As is often the case, Stu is right on... but even then, you have to be sure that you have enough room on the port side of the engine to "lean" the alternator out further.Just buy a slightly longer belt. Once you figure out the right length, buy two more and you'll be fine for six years or more.
Buy the belt tensioner, too. Loose belts are the major cause of alternator failure.
Hi, MarkJeez...just asking a question. I didn't question the veracity of your story; I just asked if anyone else had the same experience or knew how many cases had been reported.
Maybe it was a problem that only manifested itself on the M25 engine, but since the M18 used the same bracket, Universal recommended the change for the M18 as well.
You yourself even cite a failure of the new bracket in a July 2008 post on the Catalina forum:
"I just (literally last night) heard of a new style bracket failure on a friend's M25XP (1988) boat, which dropped his alternator out of the loop by failing at the top of the bracket."
How many failures of the "new bracket" have been reported? Seems like just about any bracket in that application is "prone to failure."
