"Bob, I bought the boat last y
"Bob, I bought the boat last year, had it about 5 times last year, no problems at all. I did notice the belt was a little loose last year, so i adjusted it last year ran good no problems. This year had it out 3 times and belt broke on 3rd trip out. It was a dayco belt on it already, 15420 a 42,, belt. I researched the belt and found that it calls for a 15415 41 1/2,, belt. So i bought a 15415 belt and installed it took the boat back out and ran good, went out the next weekend and belt broke. Now i know something is not right, so i bought 2 15415 belts put one on and tie- straped the other to the inside of the front mount so i would not have to go through the pain of having to get the picker back out and support the motor and remove the front mount again. Went back out the next weekend with the boat 2 hours into the trip snap the belt broke again. So now i have one belt on the boat, but i know there is a problem somewhere and i am going to TRY to fix the problem before i go back out. The water pump may have been changed by the former owner, he did not say that but it is black in color, to me that is aftermarket, because if im correct omc water pumps were grey like the block. To me it looks to run TRUE, pulleys are not rusted or pitted. The belt is being chewed up in the sides, what i have always thought is that if it chews up the sides the belt is not running true. Friend says that the front crank pulley is warped and at high speeds /rpms most likeley it is chewing it up. I started the boat and the balancer/pulley does wobble a bit when idiling, so i guess it wobbles a bit more at high rpms. I have ordered a pulley/ balancer from doug russel marine to eliminate this issue."
