Taking delivery soon and have a prop question

We placed an order back on October 1 for a 2021 23LSNPAPG tritoon. This is the 23' model that has the traditional couch seating up front, L shaped seating across from the helm and the 2 fishing seats and a livewell in the rear with dual stern gates. The boat is being equipped with the SPS+ package and a Yamaha 250 SHO VMax with power steering. The dealer invoice just shows that the rigging includes a Solas stainless steel prop. We will hopefully be taking delivery in the next 2 weeks and I was wondering what everyone's opinion was regarding prop diameter and pitch for my setup. I understand that I may have to try a few but the dealer is an hour away so I'd like to have it rigged pretty close to perfect when I pick it up. We will normally have 4-5 people on board and the kids like to knee board and wake board and occasionally we will pull the tube. I had an Aqua Patio tritoon a few years ago with the same motor and it would run about 45 MPH but I don't remember the prop specs. I'd like to keep my top speed around 45-47 MPH. Thanks in advance.

I'm surprised you haven't gotten a response by now. I don't have a combo anything like yours, but there are plenty of suggestions in this forum. More than one prop that will work. Yamaha Performance Bulletins (search for them) frequently get excellent results with the Yamaha Saltwater II prop and a pitch range of 16 to 18. Of the ones I've seen, 17p is the most common. I recently sent a 17p to one of our sons for his 23' CC (They frequently have a drag/performance profile similar to a pontoon boat of like size. He is very happy with it.)

The Solas prop may be great...hopefully your dealer can provide performance data...although it's pretty tough to match the Yamaha Bulletins...

For top speed I think 17p 3-blade will be your best best. I'm running a Q3/Enertia 14.5 x 17 and it's been very good (max 51mph). Motor is F250 and also have the SPS+ in a 23' model.

But given your desire to pull tubes and have 4-5 people aboard you may have to give up some speed to get that bite in a larger diameter or more aggressive ear. 16p will probably move you up to a 14.75 or 15" diameter and should give you that pulling power and hole shot, but not sacrifice too much speed.

I don't know anything about Solas props, so will defer to others. But the recommendations from "the prop guys" that I've seen or talked to are the Enertia, Mirage Plus and Salt Water Series II. These designs tend to be on heavier boats and more all-around performers so perfect for pontoons.

Also consider adjusting motor mounting height as that can yield a few MPH and better fuel efficiency.

Please let us know your numbers when you're able to run her!

I checked the Yamaha Performance Bulletins for the VF250 engines fitted to pontoons, and the most common are:

Yamaha Saltwater II Series
15.75x15
15.75x16
15.5x16
15.5x17

Top speeds are in the middle to upper 40 MPH range for 22-25' pontoons.

I was not happy with the Solas prop. It had a lot of cavitation problems. I went with a Mercury Enertia. Night and day difference!

I had the SWS II 15.5x17 on my 250 SHO, worked well for me. Granted I didn't try anything else, I originally just went based on the performance bulletins

I have a 14.25 18 pitch on a Yamaha 300 and I'm unhappy with it, I feel certain that it is not the best option

I was perusing the Performance Bulletins for the F300, and most of them (pontoon) have the Saltwater II Series 15.75x15 or 15.5x16 - may be something for you to look into.

Yamaha SWS II 15.5 x 16 or 15.5 x17. I have a gsr 2250 with ESP and VF 250. Have run all the above on my boat (solas Lexor 17, sws 18, sws 17. The 16 is slightly slower 48ish but better bite for pulling skiers and tubes. Solas is efficient but the sds hub on the Yamaha props is much nicer/smoother to operate. Even my wife could tell the difference. That VF likes to run on the upper side of its rpm range so I’d guess you may end up with a 16. Good luck
