Benny recommends I believe a certain prop for my boat but open to spend some extra $$$ if there is a better prop out there that will offer more performance. I take delivery of my 2013 qcw 25 with f300 yami outboard in a few weeks. Just a few more mph is worth it to me to spend the extra funds. Thanks and thoughts???
 
Mercury Enertia.
 
I second Enertia. Great all around prop for pontoon boats
 
They might need to know what prop you are talking about to have any idea which is better. Just a thought.
 
Its a Yami prop I believe recomemened by Bennington 15.5 17 stainless SDS....
 
The Enertias come in 1" pitch increments but as the pitch goes up the diameter goes down. The 17p is 14.5" diameter and the 18p is 14.25" diameter. I believe the 19p is 14' diameter. Try the mercury prop selector. I just looked and the prop selector won't work for you. It doesn't list your engine. You might want to give them a call as well as the Prop Gods in Florida.

Recommend finding the oldset/respected dealer in your area. The variables (speed, hole shot, GPH, etc) for prop selection are too numorous to say "This works on mine so it will work on yours." I live at 3900 ft. What works for me will be significantly different than someone at sea level. My dealer nailed the prop size on the first try because he has tried hundreds of combinations over the last 25 years and is pretty good at it.

I researched for two weeks before my boat was ready and I was all about discussing with my dealer. His combo wasn't even in my selection matrix but he put it right between the uprights first try.

Learning the physics is one thing. Applying it to your boat on your lake is something else entirely.

Good luck and let us know your outcome.
 
We don't see many Q's with 300 hp on this thread. Yamaha thinks enough of their Saltwater Series II propellers to put them on their high horsepower tritoon performance tests @ 17 pitch.

Depending on slippage, you might see as much as 49 mph. That motor ought to really be something.

Yamaha says:

Saltwater Series II Propellers A powerful choice for today's larger offshore boats. Saltwater Series II propellers are a highly-polished, larger diameter design. Aggressive rake and extra cupping on the blades provides superior midrange fuel efficiency, along with excellent anti-ventilation characteristics. For offshore fishermen, that translates to longer cruising range and better handling in rough seas. Available in four pitch sizes and matching right and left-hand rotation for single or multiple engines. For 2-stroke V-6 150hp - 300hp, and 4 stroke V-6 F200 ~ F250.

Thanks. Great data. Makes me feel the yami recommended prop and this engine combo set forth by Benny maybe a good call. I want to break 50mph but will be happy with 49 mph that's for sure. I wonder why we don't see many Q's with bigger outboard like the f300. I feared I was leaving much on the table not going with the f350 but beyond some torque the added weight plus gas thirst plus added cost I passed. Thanks again all for the advice. Much appreciated.

We don't see the 300's because it's a matter of money--and not enough of it. The boats are absolutely knocked dead gorgeous--simply put. You'll certainly be satisfied with the power you have Get much over 30 mph and your passengers get a little excited. Go over 40, and they're scared. Run 50 mph, and I don't know how your passengers will feel.

Well if I was Newport's passenger I'd feel GREAT!!! Especially if he let me drive!!!! Woohoo!!! I miss Ccando talking about his big power, I'd LOVE to go for a rip on one of those boats!!
 
Just remember that pontoons a short time ago were a bunch of 55 gallon steel drums welded together. They've come a long way, baby.

And now they're often running 45-50 mph, handle great and haul large numbers of partygoers.

And pontoons/tritoons are really the only segment of the marine retail market that's doing well. And Bennington is now the leader in the market for pontoons/tritoons and their sales continue to soar.
