SUCCESS!!! To refresh your memory, I drilled a small hole in the water inlet at the top of the midsection to spray water on the starboard side of the mid and shift linkage. I also shot some grease to the shift handle and that may have helped by preventing exhaust from leaking by the slightly wore out bushing. The shift handle stayed pretty cool, the upper mid was pretty hot but didn’t boil the water when I came down from being on plane. Got 22mph with my 3 blade aluminum (10” pitch) prop on the 13′ Feathercraft, not bad for 10 horses.
