[natedog337]

Hey guys looking for some advice. I have a 26 ft pontoon with 4 stroke Yamaha 2011 with 38hrs on it.. Last year my first season I upgrading to a 4 blade prop with no issues... Prior to this season I removed prop to grease and reinstalled correctly.. It was installed and torqued properly.. Well took it out for its first tide this year and when I get to 3000-4000 Rpm it blows out and revs high and appears to slip.. Thinking I hard a spun hub Ireinstalled
My original prop and same issue except not as noticeable until about 4500-5000 rpm

Any advice on what my issue may be

Thxs everyone

Anything different with OB height? Trim? Bottom condition(s). Weight balance?

Well I feel pretty stupid. I've only had the boat 1 year and I found the sweet spot on my trim last year and used the gauge this year to set it exactly in the same place. Well i took a ride with my mechanic after trying to figure it out all day and the gauge or trim sensor is nit reading properly. Motor was trimmed to high. When I put it all the down and eye ball the trim, off she goes with no problems... Well it worked out with minimal aggravation thxs again

My first post here, seven years ago, was something stupid. Easy to get sucked into your own BS if you don't always doubt things. I usually do, but that day . . . Live and learn. Your situation sounded like typical high trim blow out for sure. Thanks for the follow-up.
