Re: Any hope restoring a Evinrude Yachtwin 3532A?
Did you drive the pistons out with a hammer on the rod caps ?? If you did, you probably deformed the rod caps, since they are aluminium and not cast iron. If thats the case, I would try to place them in a bench grip and CAREFULLY pres them in on the sides, and try them on the cranck a couple of times. Were the rodbolts tight when you did it ? If they were the entire hole would be oval, then, both caps and rods. Be aware of risk of metal tiredness !! Be carefull.

I only did this because the motor had sentimental value to me, and I knew it was running perfectly before being parked. The first tank of gas during and after a decarb was run at a 16:1 gas/oil ratio. I certainly wouldn't try this process with a precision bearing motor, but the old 3's are a bit more forgiving.
