Default 22 Scarab 454 mostly stock

'98 22 Scarab, 454 (non-mag, carb), stainless marine exhaust, otherwise stock.

Currently, I run a 25P Mirage Plus 3-blade prop. THe max rpm I've been able to hit is about 4200rpm, which winds up at an indicated speed of high 60s (realistically, probably low 60s, based on other boats with GPS that I've run with). I've tried a Bravo 1 4-blade 22P, and while it gets up on plane nearly instantly, the motor winds out to over 5K and I only get an indicated speed of around 45mph.

With the Mirage 25P, I occasionally get some blow-out while getting on plane, especially if the water is a little churned up from other boats. It planes reasonably quickly, even with a full load, but not nearly as well as the 4-blade 22.

A friend has a few props I can try, but I don't want to waste my time with any props that are clearly not going to work well. I'm curious to hear any recommendations as to what props would be worth trying.

Thanks!

Andrew, you can try my(actually Rays) 23 four blade if ya want, it was(is) a Mercury Offshore, it says 23 on the hub, but it has some work done to it, Ray says its a 24. It is a smaller diameter than a bravo, not sure what it will do for ya, but worth a try one day. I may be interested in trying your 22.

I Think The Rev Limiter On On A Stock 330 Hp Is 4850..when I Was Stock Power A 23 P Mirage Labbed Was The Best. Did About 64. You Need A Round Ear Prop To Get The Bow Up, Bravo 1 Or A Old Mach Stern Driver . You Really Need More Power , Look For The Thread 454 On Roids

I'm not really looking to go a whole lot faster in terms of putting $ into the motor -- but if a prop is all that's holding me back from more speed, I'm all for trying it

You will like the Revolution 4 much better than the Offshore/Trophy Plus/Ven-Sura. (they are all the same)

We have the Rev 4 for testing if you would like to try one.

The Mirage Plus will have the best top speed. Especially if it is Labbed to the boat. The 4 blade props will give great all around performance.

Would that be a 25 or 23 in the Revolution 4 that you'd recommend I try?

I ran a labbed 25 Mirage Plus with a stock 454mpi. Ran 66-69 GPS. Same boat with a stock 502MPI ran 72-74 GPS. That was on a 1996 22 Scarab. I tried lots of props, the 25 Mirage was the fastest. The boat handles much better with a 4 blade , but it's a little slower.

I think the 23 would be a good starting place. Let us know if you would like to try one.
