Boat has a permanent fuel tank built as a step up to the front deck, I switch back and forth to a surface drive a couple times in a year so premixing fuel will be a little pain in the @#% every time I switch back to the Prodrive.

I have never seen a 40/50/60 Merc oil pump fail. It's usually a pinhole in one of the oil lines that gets you. The larger Mercs have a nylon drive gear on their pumps, the 40/50/60 has a metal drive gear.
