Cant get it right!

Also you probably don't know how to drive it to 70 and yes you need to know how to drive it!

[basscat tyler]

I don’t have it all figured out, but I wouldn’t come on a thread and tell people how to post their help either. I guarantee you don’t have everything figured out either....or are you the know it all who spews their knowledge on all of us less than perfects???

Evidently just go to this guy for your answers

Haha! Yeah, he really is good at telling people what to post!

Sounds like to me your running at the right ht if your measuring it all correct . So your running heavy some where . You might be water logged .

Is the bottom of the boat all boogered up ,Skag bent or prop shaft is bent . All these things matter .

no, it’s clean as can be

I dealt with lower speeds and poor performance under a load. This was after years of running at the same loads and same setup. I tried everything, thinking my props were ok. Finally took them both to be reworked and there it was.
Back to my regular top end and very little loaded speed loss. If you think everything else is right, it’s time to let someone work their magic on the props.

I also agree that the 2.5 doesn’t carry a load like the 3.0. They are great running light, but can fall off quick when loaded.

Motor is turning 6000 rpm. 120 on all cylinders

If you want bottom end and acceleration with a load it should do it.you could always ad cup if your a few rpms over

My answer to your original question would be to not get a diff prop, but to work the 25 Tempest. 26 Tempest are usually not right out of the box. The Fury is a good prop, until it wears the cup at all, then it has no lift.
Tempest is great all around prop and if you tell a prop
shop all the right info, they should be able to add some cup and get you where you need to be. I would prop that motor to run right at 6000 rpm light. That way you are still turning enough when you have a load.

Send the tempest to mark croxton with your numbers. He'll make it work. Night and day difference in the 2 I've sent him..

Check your prop slip numbers. Prop slip% = 100 - 100( Actual speed (GPS)/Theoretical speed)
Theoretical speed = RPM x Prop Diameter/Gear Ratio x 1056
Using your numbers, we get 5900 x 25/1.87 x 1056 = 147,500/1974.72 = 74.6
Prop Slip% = 100 - 100 x (66.8/74.6) = 100 - 100 x (.895) = 100 - 89.5 = 10.5%
10.5% slip is not too bad on a bass boat. If you can turn a 26 prop to 6000rpm, your speed would be ~ 71 mph assuming you keep 10.5% prop slip. I know the numbers are not gospel, but you can get a good idea of how your boat is performing with different props. PM me if the calculations don't make sense.
