I'm just kid'n ya. Only the very oldest generation Mercruiser alpha outdrive derived originally from the Mercury outboard inline six lower-unit. The old rounder gearcase, not yours. Your year Alpha Gen ll type Alpha SS was a very good, much improved design. Nothing wrong with them at all if kept within the horsepower perameters it was designed for. Last for years. Was meant for the capt. who is a gearhead marine mechanic who enjoys, & sometimes hands out ridicule with a smile. inside joke.

I knew that, just pulling your leg also!!

I work for the company that builds these boats, and retired from the NAVSEA office that issues them. Trivia question-What are the knotted lines called that the crew members are holding, and why do they hold them?

just be careful. torque & alpha anything dont mix too well.

I had an Alpha 1 behind a 330hp 454 Magnum. Called out to Stillwater to see how much more power it could take, and was told "None! Don't even turn the timing up!"
Merc-Cruiser is right, in order to last you need the right prop, a soft hand on the throttle getting on plane, and good lube oil. I stayed away from synthetic, too thin and made it shift very rough.
