I can't resist browsing around in an unfamiliar boat supply store. Even though 99% of the items are the same ones that you see in all the other places, I usually find at least one item that is new to me.
As I browsed through Westside Marine outside of Port Townsend, WA a few weeks ago, I spotted this.
I have a couple of pumps for filling the engine gear case with the smelly messy lube. The threads never match the proprietary Honda threads. Here's an adapter that adapts Honda to the rest of the marine world. Made by Sierra a division of Teleflex. Two part numbers on the packaging;
18-9794 and N3500.
