150 optimax........alternator bolt snapping

[Captn C]

I've had three break on my 1999 150hp OptiMax, but I have not had one break all last summer. The guy who finally fixed it said the bolt was not properly torqued. I was breaking it about every 10 hours until he repaired it. I put about 150 hours on the last bolt. I even bought a bolt that I carry in just case, so far I have not needed it.
