Need help with props..........

[getrdunn]

am close to completed my 496's for my 78 spectra. The boat weighs near 6300 pds completely rigged. The original/prior 454/330 set up ran 23 pitch clevers at around 4700 to 4800 RPM's. The trannies are 1:1 and the drives are 1.5. The new rebuilds are expected to be close to 600 HP plus or minus. Will be certain after dyno time. I plan to turn the new rebuilds somewhere between 5600 to 5700 RPM's at WOT.

Any ideas of what prop size I would need??? I would like to purchase some real soon. There is a good used set of Bravo one 4 blades - 26 p for sale on the board and wondered if this might be a good starting point.

Thanks for your help.

Due to the HP increase plus the desired rpm levels you wish to run with the new power, the pitch should remain in the same ball park you were before.

Test props in the 23-25 range for a base line.

Call us if you need some test props.
