Piston Rings for 1984 Force 85 HP
by David from Whitefish, Montana on May 14, 2013
Rings came in pairs. One ring fit same as original. The other did not match original. I am waiting several weeks for Sierra to figure it out and get me the correct set of rings. In the meantime my motor is sitting there in pieces and I can't use my boat. Not very happy.

Incorrect piston rings
by Bradley from Waverly, Ohio on July 15, 2012
It appears the table on the iboats web page is incorrect. I have ordered OEM rings from another supplier which references a different model number than the one listed on the iboats web page. I would assume others are having the same problem if this is the case. We'll see what happens.
