I am running a 25P on my 99 225EFI on a 99 Cobra Viper boat.
I have a really hard time getting on to plane when I have a full tank of gas, or livewells full, or just a load heavier than only me.
I have tried adjusting my vents. There is no combo that helps, from 1-2-3-0-med sized plugs/large plugs, etc... I either bog down really hard around 2400ish rpm until it FINALLY pulls over and drops down or the prop spins out if too much is taken out of the vents.
Once I am up on plane, the boat performs good. I run about 5800 RPM and about 68MPH on GPS with a heavy load.
Prop/pad is about 3.5" below on the manual jackplate.
So-- I feel like I need to experiment with different props. But I do not have the time, money, want to/desire, or convenience to buy and try, borrow and return, etc...
I'd like to narrow down my options and see what prop I need to try and why?
I have been told a 24P tempest plus.
I've also been told to go to a 4 blade....but noone can tell me what pitch I should try.
Can you guys offer some options?
