I have one in aluminum 13.75" 3 blade 21P. I can find out what there are worth and work you a deal if your interested. Where are you at?

I just saw this.. I am in Barrie, and I would be interested in a prop. I need to see if there is a spare in the boat when I pick it up on Saturday regardless...

Re: buying a prop need help
 

Just to throw this out there because it happened on my bass boat! My prop was slipping and after some discussion and looking from a local prop guy (Old guy with lots of knowledge), all he did was put a lip on the backside of every blade which in turn caused the prop to catch more water, in return no slippage!

Yep, i've seen that work. That's why prop blades with more pronounced 'cupping' tend to perform better. You can go too far though.....

Re: buying a prop need help
 

One more question about buying a prop. Do i need to take the prop off and determine how many splines there are or should it be universal for a set type of outdrive? And also when i order one does a hub come with it to match it?

Re: buying a prop need help
 

It depends.....some places sell the hub kit as part of the prop package & some places separate the two. If you look at the i-boats site, they tell you what hub kit you need for each prop and application.

Hi,

I have a 1993 2350Z with Merc 7.4 and Bavo 1, but unusaul outdrive lower with oil drain hole behind prop/ It had a 4 blade 15.25" dia 15" pitch prop. The max rpm is quoted at 4800 for the engine, but it will easily exceed this if I let it. Does this mean I need to go to higher pitch? I am relatively new to baits and am learning as I go. I forgot to mention that the boat also has the switchable option for through transom exhaust. Any advice is welcome. I guess I should also mention that I am in Utah and the altitude where we sail is usually around 5000 ft.

Yes, that makes a big difference. My boat was from CO where it had a 19"p prop. Here in IL I use a 23" You may also have a 1:1.65 gear ratio also. It does sound like your under pitched on that prop, a 17"- 19" may work but in hot humid weather you may need to switch back to the lower pitch.
