No and I think you guys and girls are the fortunate few who know the Truth about Sharrow on a pontoon. I spent lots of time, gas and trips to the lake and really wanted it to work but unfortunately it did not and was not even equal to an SWSII. JDB

No Data points on the exact boat but on my 2010 Bennington 2275FSI ESP with a 250 Yamaha, The Sharrow Props (They Tried Several) were Not Even Equal To the SWSII. Eric with Sharrow was in my boat on my lake doing the testing. He has the numbers and I have the numbers and they refunded my 5k...

The "Traditional 15.75 x 15" prop they were using must have been the worst performing prop they could find bc compared to an swsII the sharrow was inferior on all data points except one. Either 5 mph or 10 mph it was slightly more efficient. All other data points it was inferior to the SWSII...

Sharrow Testing

Top Speed Jan1 cool air slight tail wind

Best cruise fuel economy 3.7

Sharrow Props are essentially a Stern Lifting Design and that's not what we are looking for on a pontoon. Where you see them really shine in a performance report or boat test is in the cases where they are able to lift the stern and get a heavy boat on plane at a lower mph and then show numbers...

That's a great question and TBH I didn't know there were different options on the plastic rubber parts but this is what I have left from the testing so I may have misplaced one box but I can study the pieces closer if there is some useful info on them.

i Have now tried several Sharrow props ,Merc Enertia, Enertia Eco, several SWSII and one SWSII HP. The SWSII or SWSIIHP beats them all IMO and the quiet engagement SDS is a plus. Best cruise efficiency + top speed came from the SWSII for me and I hated the clunk on the Mercs. JD

I agree that the problem is something other than balance as the prop is turning too slow for imbalance to really show up. Prop imbalance that could be felt at idle speed would likely be really bad at midrange and top RPM. Slight contact with the bore in the lower unit housing can certainly feel...

Dry Hull weight on my boat is actually 300 lbs less than the 247 Sportsman Yamaha apparently used for testing and advertising the props. We also tested with a Light Load - 2 passengers and one ice chest and a Medium Load (for a pontoon) - 4 passengers and 2 Ice chests with very little change...

Have run the Enertia but unsure on the rake difference. The SWS 2 HP is a full inch larger than the Enertia contributing to the contact from the higher rake. Low speed vibration and bumping feel are noticeably worse. (No,Nothing was hitting) I'm one hole up from lowest. Water surface disturbance...

No pics yet but disappointed in the performance and fitment. It has so much rake that they hit the steering trim tab which had to be notched. It also has an increased tendency to porpoise that feels like it stops short any attempt at a top speed run. Certainly not impressed thus far.

I will argue thats not the perfect scenario if the fully loaded boat only pulls you down to 5600 but that might be a topic for another thread.
