Wrong part
by Eric from Bloomingdale, New York on August 05, 2011
It was obvious when I was speaking to the person on the phone they had no idea what I was talking about. I even provided a part number and they still go it wrong. You need more than a person looking through a catalog of parts, you need educated people who know boats on the other end of the line.

Q:
Will this work on a 1981 evinrude 75hp?
A:
No. For 75 HP these typically work for years 2000-2004. To find correct piston you will need to call us at the number at the top of the page with your engine model number.
