Review on 🔧 High-Quality REPLACEMENTKITS COM Yamaha Gasket - Replaces OEM Part 90430 08020 00 by Wendell Chapman

After a long search for a matching 20hp Mercury 4-Stroke Outboard I finally found these Lower Block Drain Plug Gaskets. I've been using regular Merc gaskets for a long time only to find that they are too big for my smaller connector model. These gaskets fit perfectly on my M8x1.25 floor block drain plugs (standard 8mm spacing) with almost no play. I hope they hold up. I will check often during boating season. Incidentally, I determined the exact size/pitch of my end caps by buying various metric nuts from the hardware store and then seeing which screwed in best. The purpose of this review is to help others who are literally in the same boat.
