Default Prop clearance specs?

And you like it? How does it compare with a regular prop?
they do have a 17 in 3 & 4 blades that'd fit / work for me.

I had been running the traditional merc props before I went with these
guys. So that is the only type I can really compair them against. Finish
is excellent and they are very smooth running. On my current bowrider I
have used their 19 inch 14.5 aluminum and currently have a stainless of
the same size.

The boat is a Crownline 225 w/5.7 efi rated at 280hp w/a Alpha genII
leg. This give the boat good hole shot for skiiers and the boat tops out
in the 50's on the speedo. That is alot faster then I care to run it. To
me the hole shot is more important.

They are made locally in Georgia, thus they are not cheep a imported
type. I will switch back to the aluminum if we have a dry summer as
predicted and the lake get as low as it did last year.

I like the traditional rubber hub over the merc plastic core type. But
that I guess is just a personal preference. I really can't think of why
I would try anything else.

I hope this helps, good luck on your search. Oh the local Bass pro Shop
carries them. But I have always purchased mine direct at the boat show
and saved a few bucks.

On another note, When I had a Crownline 210ccr w/5.0LX merc I had tried
a four blade as well. It was a 16 as that was the smallest diameter that
merc carried at the time. All boats are different so it is hard to say
if the results would be even close. But it tended to made the stern run
higher resluting in a rather flat running angle on this boat. So I went
back to a three blade. since the boat had tabs It was easy to bring the
back up if the cod=nditions made it desireable.

Just out of curiosity. What rpm are you turning at wot with the prop
you have? And what engine do you have?


4100 RPM -- should be 4400-4600
That's in a PERFECT day.. flat water, no weight, etc etc etc.
Hole shot sucks.

5.7 gm based mercruiser (350ci) Alpha1 1.47ratio, 19" pitch 3 blade

Regarding the prop -- yes; I can find a 14" 17pitch prop; but they're on the
cheaper side of performance... When I get into 4 blades, they seem to get bigger
as the pitch is decreased.

I'm sure I'll find it.. the prop shop said they wouldn't charge me much to take
some off the edge if I need them to; so I'll probably go with an aluminum and
have them shave it if needed.

Since you have a merc

they use a traditional rubber hub.

Good Luck
