Prop size for Regal boat

[duncaj]

I was instructed to leave this question here. I have a 1998 Regal 2100SLR which requires a new prop. There is no information in the documentation regarding the proper size and the current prop only has two series of numbers on it that make no sense. These are LP0829 and 3850302. The engine is a a 5.0L GLSX Volvo Penta with a Volvo Penta Cobra SX outdrive. I understand that the pitch is determined by the RPM at WOT and I know that the boat red lines the RPM before getting to WOT, so I should get a higher pitch prop. But when you do not know the details of the prop that it on it, what do you do. What diameter do I need. If you have these answers, please let me know.

Unfortunately I am unfamiliar with Volvo Penta and was unable to obtain any information on the prop you have. You can take the prop to a prop shop who could tell you the pitch and diameter.
