I have a Yamaha F 70 that I bought new in 2011, all maint up to date no issues until this week. Motor starts and runs fine until 3000 RPM then there is no power and the RPM shoots way up. If I lower the speed below 3000 RPM it works fine, Any advise would be appreciated. I use non ethanol gas with marine stabil every time. The water jet (pee stream) seems the same as always. I even flushed out the water hose. thanks

I had placed a work order with Texas Boat World in Killeen about the problem the same day I posted this. Wes Walker from boat world replied back. -Sounds like the prop hub is spun. Bring it in anytime. And thanks. I had another prop changed it out and the problem was solved. That's integrity right there. Thanks for good advise.
