What speed would I expect at say 3500 rpm and 5500rpm with this prop?

Well your not going to get to 5500 rpm anymore, when properly propped (oem 14x18) or what OJ recommended, wot rpm should be 4200-5000 rpm and 47mph as per the owners manual at sea level, a more realistic mph will be 44-46 mph imo.

Per the manual, WOT is at 5,000 RPM's so you are definitely over-reving.

I think I hit around 43-44 MPH on my LT1, 1:1, 205, elevation 6,000 ft.

When I switched from the 13 x 13 factory prop to an OJ prop, I gained a bit more hole shot and also better top end. The CNC, next generation is worth upgrading.

I agree with Eric! He knows his stuff and awesome service and products. I have that same prop on my powerslot trans boat and its a monster.

Your boat never left the factory with 13x13 on a powerslot trans. it had a 14x18 stock. someone changed the prop to the incorrect one.
