propeller selection for my 1970 240SRV

[Oldboatlover]

I am trying to sort out my 1970 240SRV. It has an optional 215H drive, much larger than typical, with a 19" prop. I am looking for the original propeller specs to give me a baseline, but so far no one (including Sea Ray) has been able to go back to 1970. Any suggestions?

Sea Ray has a schedule for your boat and prop. I think the 4 blades offer a bit better performance.

You might check the Sea Ray table, but I have a 260 SRV from 1978 and went to a 14R19 four blade with good results.

Where is a good place to get a prop for a boat this old?
