looking for some insight on prop choice, I got a 2000 cougar 22mtr with 670hp 489 and 680tq. boat works awesome have owned it for 2 years now. boat will run 90-92 on gps with a 28 pitch bravo 1 prop labbed finished. boat gets on plane with no effort at all, just wondering if it could handle a 30 pitch or 32 pitch or if im just chasing more mph in the wrong places.

boat just has a bravo one outdrive 1:5 ratio with a imco nose cone


and if I posted this is the wrong place sorry. new to any kind of forum just looking for help before I order a prop

Call Doug at spinellie brothers and he will set you up right, great guy and great prop maker

For that kind of HP in that small of boat you should be over 100, need to know RPM of the motor with that prop and what the motor should turn at peak HP. That hull should have a lot of natural bow lift, I would think a Hydromotive Q4 would be a good prop.

Yes, we need the answers to those questions. The actual rpm when you hit 91 mph.
I think the Q4 is a good choice but on the 22mtr I reduce the diameter from 15.5" to 15".
Also, there is likely a adjustment to the B1 to help.
But, need the numbers JRider requested first as well as prop shaft depth in relation to the sponsons.

Boat runs 5300-5400
Sorry for no reply just gave up trying to get more top end everything works so well On it. I end up finding a buddy that had a 30pitch bravo prop, was beat up and old and not finished. And ran 96 with it. But had a hard time pulling rpm with any load in the boat

Now is the perfect time to have us Lab Finish the prop.
We are having a winter special the cost to Lab that propeller is $340. This includes a final adjustment if needed.

Thanks,
Brett
