Hi folks, I am replacing a broken piston on my 135..Apparently there were 2 different pistons for that year. My piston number is 765-7442 with the letter "A" above the numbers. The rod is 644-818141. The cylinder is not damaged, and I have honed it out..Any help with the Sierra part number would be GREATLY appreciated..Thanks, Rich

Rich, Get on the Crowleymarine.com web site and you can look up the part numbers, by motor serial number. I believe the port and starboard pistons are different.

I will check that website. Yes, the port and starboard pistons are different, but they made 2 types for each. Rich
