1993 Johnson 150 Faststrike Piston Rings.

[James R]

Replacing STD rings on the port side. Pistons good and bores honed nicely. A Marine dealer had WSM ship me three sets. I specified for OEM pistons. The rings don't fit of course. They are too thick. Number on the pistons is J434504.
Can't find that number in the BRP parts catalog. I will get OEM when I am sure that that's what I need.
Can you help please.

The WSM ring is a RIK ring and will fit their piston only. The OEM part # is 436353. Promarine and Serria carry these and they will fit a oem piston. The Promarine # is 6353 and the Serria is 18-4088.
