Hello from the US,

I have a 1991 Rinker Festiva 230 with a Mercruiser 5.0L engine (230hp). I bought the boat last year with a beat up prop that I can not even read the numbers on. I replaced it with a variable pitch, 4 blade Propulse prop. I would like to hear some thoughts on proper sizing of an aluminum prop. I don't think the adjustable runs true nor is it as efficient. Thanks for your help in advance.

Tom
