Force 150 parts required

[skeer]

I have a Force 150 that has 2 thrashed cylinders. Took the block down to the nuts and found #4 & #5 pistons wrecked. #1 is on it's way out as well. Can anyone point me in the right direction for 3 used standard size pistons for a 1992 Force 150? I believe the diameter is 3.375 inches. Also, if anyone knows what the min/max limits are on the cylinders before I have to go to the first oversize it would be appreciated. Thanx for any help you can give.

Reposting this in the hope someone has some suggestion / parts from a B.E.R. engine.

According to the Clymer manual 92, 150's have a Std. Bore Dia. of 3.3750 - 3.3762. MAX wear taper and out of round is .002. measured at three places - 1/4 in down from top, 1/4 in up from exaust port and 3/16 down from lower edge of intake port. ALL measurement repeated 90 deg. from 1st measurement. If .002 is exceeded they say you must go to next larger piston - .010 over<br />Hope this helps
