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.

The problem is you are against the rev limiter so hard its difficult to say how much power its costing you. The RPM range for WOT is 5000 to 6000. Max power is 5500 - 5700 and its dropping off after that. If its a salt water Series 2 something is not adding up with that small diameter. You...

Not unless you want to fix most of your problems like over revving, excessive fuel burn and low top speed.

A quick update on this back ordered prop that was delayed an additional 2 months after the first 3 month delay! My 19" and 20" versions are finally scheduled to arrive tomorrow 08/09 and I will post pics of one next to an inertia for comparison followed by lake testing hopefully in a couple of...

Assuming the tubes are clean - re prop for that extreme load and you will definitely see an improvement. Multiple Large Ice Chests and Multiple Large Peeps are not the friend of a 150 shod Toon but getting the engine up to 56-5800 will at least get you close to a happy skier situation!

I couldn't agree more. They've got the MSRP so jacked up now that they can play every financing / trade in, extended warranty game in the playbook and still clean your clock! Who will be too big to fail this time??

Thanks Alot Potomacbassin' I had not seen anything on this and it could very well be my perfect prop. I'm guessing they finally built us an Enertia with slightly more diameter And SDS! Bravo Yamaha! edit: Backordered till 6/10 - Oh well it should be worth the wait.

This is some of the ugly that will be under or inside your console and that might be the brain box you are referring to. Not hard to see why they don't show this spaghetti in the Yamaha Rigging literature pic above but it works like a dream!

Sorry PartyBarge I didnt mean to mislead you or anyone else. When I mentioned overdrive I was talking about the propeller itself, as that is essentially our final drive gear ratio and the 52 - 5300 RPM I'm turning at WOT effectively works like an overdrive.

Exactly !!
