I have gotten a set of pro marine "persan" cast 3 ring .030 pistons for my '86 115.
These have floating pins as opposed to the press fit originals and are somewhat smaller because they can easily be slid into the old piston.
Now it seems that I have more play in the needle bearings in the con rod.
Is this a source of concern?

The wrist pins should be the same size as OEM the clearance is in the dia. of the hole. Just a couple of questions, did you use new bearings, did you count them if so you should be alright

Thanks Laddies. You are right.
I got it backwards. In fact it is the old pins that can slide easily into the new pistons.
