All mine would be standard bore. I do have a new in box 150 piston that is .015Quote:

I tried to order pistons from Mercury using the original part number for the 1350(135 hp) inline from 1971. All the Piston numbers superceded to 1 part number that has the power port and notch. Seaway pulled one off the shelf for me and looked at it. Does anyone have a parts book for this engine?
So six new 0.020 without notch. Coated skirts? Nope I checked.
It's apparently going to be a special order piston, the other guy I had spoken to was wrong, so I can probably have them coated. I believe the Pistons come anodized normally. I'm waiting for my machinist to check both blocks out first.
what is an unassembled, T2X worth, just powerhead? I might have one in the garage...

I don't have any oversize Charlie.. But somewhere in the dungeon is a 90 HP crank with 6 non ported pistons in fine shape. Whether they are notched I can't remember.
