I called the previous shop that did the maintenance on the boat. They recommended NGK-5599 LASER IRIDIUMD ITR4A15 which seems to cross to AC Delco 41101. I guess Ill try to gap the ones I have to .060 or return them and try the iridiums. Learning how to redo the entire cooling system was easier than trying to figure out the right spark plugs.
