It sounds like budget is a concern...I second the Hustler Props. Cheap and decent performance but with the caveat the edges of the blades seemed to chip far easier than my OEM prop which was the same as your OEM Prop. Even a little fine sand and the edges would chip. I had 6 of them for my previous boat with your same engine. I would pop a 19 three blade on there and go from there. They are so cheap, it's impossible to break the bank.
