Hmmmmmmm.....
The Stiletto SS 3 blade 19X17.5 on my 5.0 Mercruiser/Alpha 1 WOT is
4600. 6,000 lb 25' boat. It has been o/hauled twice in 16 years; picked
up 150 RPM from the slight change in blade profile. I'd say your motor
is not performing up to snuff, or possibly the Gear ratio in the
outdrive is wrong... Plenty of C.I. to run your original prop at 4500+,
unless the props a dog and not designed well. (probable).

Thanks to all -- who helped with my initial question.

(Current: 22' cuddy -- HEAVY boat, 5.7 alpha1 3 blade SS, 19pitch,
4100 rpm
(should be around 4500)

After poking around mercury's website, and talking to a prop shop;
I've narrowed
down my choices to these:

Revolution4, 4 blade 17 pitch
Vensura, 4 blade 17 pitch
Enertia, 3 blade 17 pitch

I'm leaning towards the revolution4 -- but it is pricey; so I want to
get a bit
of real-world, non-salesman based opinions on it.

Thanks

I got an Apollo SS 13 1/4 X 17 it runs my little boat 40 mph with a 90
HP motor. IMHO They work great and are relatively inexpensive.
