Prop question

Basscat Sabre 150 std opti. New 23 tempest plus. Always hear that bass cats don't need much trim, however mine does. At 4 1/4 ptp I have to trim a bunch, probably at least 80 -90 percent to ge the bowlift needed to get the rpms to like 5700 (62.7) mph. If I raise the motor at all I get too much slip and loose all lift and speed. Would it make sense to add cup with hopes of being able to raise the motor a little and hopefully get the max rpms without having to run so deep? Fortrex on the bow with one helix 7 and a medium amount of rods and tackle.

I think adding cup will lower your RPM'S, which will be bad for that motor.
What is your WOT water pressure?

[yandeltx]

15 psi

With water pressure at that reading you will never be able to raise the motor any higher.

I will double check it next time I am out. Sounds like I better leave well enough alone.

@Yandeltx - come up to 3 1/2” p2p and you’ll trim no more than 50% for the hull to lift and fly. You could have a bum Tempest and need to send it to Mark for a B&B. My ‘08 Sabre has a 150efi and turns a 24 Tempest that Mark has worked. My stock un-worked 23 Tempest has run 65 at 3.5 p2p on the limiter. The hull is weight critical in front of the console - carry weight in the back or it won’t lift. The fortrex is costing you 1-2mph over the original motorguide.

JStew....thanks for the feedback. I will continue to work with it.
