Just looking for some help on a new prop. Went to a new lake this past weekend and ruined prop. Pulled off old prop but stamp is unreadable to know what was on the boat. I was always happy with performance of old prop. I have a 1999 Shabah Z212 with the Mercruiser 5.7L 2bbl carb and no modifications with Alpha 1 outdrive (unsure of gear ratio). I measured old prop from center to edge and get 7.5 inches (15 inch prop). Just not sure on pitch. The more I read on props the more confused I get. We do tube/ski/wakeboard from boat. Boat at 800-1000' elevation. Thanks in advance for any help

I'll assume you had a 3 blade prop so you probably had a 19" pitch prop with that boat.

Thanks for the help mikeyt. I was hoping you would help me out. So a 19 pitch 15 inch prop makes sense for my set up? Based on all the past posts I read through 19 pitch seemed to be talked about as the most common pitch for similar boats. Wasn't as sure on diameter or how much an inch difference in diameter makes. Thanks again.

Anything between 14" and 15" diameter should be fine.
