I have a Yanmar
51 horse. I shreaded a belt to the water
pump and alternator
in November on a trip from Virginia to St. Martin. Only sign of problem was engine overheating
. No noise
no smell. Changed the belt with no trouble. Checked the belts before the return trip, OK.
On trip back broke the same belt, replaced and did well, checked a couple of times, OK. There are 4 other belts in front of the broken one. Belts are close but not touching.
What is the likely cause that I can check into?
