I could be wrong but sounds like you have have something in the Starboard Pump/Impeller. Have you looked?

 

[CDubya]

Yes, I looked, and nothing. I Was even stoped at a boat check for invasive aquatic species. They looked thoroughly through everything right before we launched. Usually get on plane almost immediately even with 10 people in the boat. I looked up the altitude of the lake, 4580’
that doesn’t seem that high to me and it would effect both engine’s the same wouldn’t it?

When one of my engines runs up to 8000 and the rev limiter kicks in, it is because the engine is having issues with thrust do to weeds in there. Once I do the reverse maneuver to clean them out I don't have an issue anymore.

Was just taking a shot at it for you.

Yes it would affect both engines, you are way to low on thrust.

I would say 7200 RPM at high altitude sounds right. Black Hills must be 4000-5000' right?

Just saw the previous post. Oops. Anyway, sounds like you are describing cavitation in the starboard engine.

You could also look at the sealant in the gaps in your intake. Mine were crap from factory, I ended up resealing them with life seal caulk. It seemed to give me about 2-3 more mph on average. But I boat in a lot of wind and current so it's hard to calculate, but I believe it made a difference. In your case it could be cause for cavitation.

It sounds like I have cavitation

It certainly dosen't take much to get cavitation on these pumps. We were out yesterday and got stuck in the river waiting for the bridge to open up. Lots of duck weed floating around. Once on plain you could hear one of pumps just did not sound right. Ended up stopping and pulling the plugs and there was some duck weed still churning around. Also make sure there's not a small stick wedged on the prop. Removing the pump is very simple. Maybe worthwhile to simply pull it to check things out?

So I got under the boat and took a closer look at the intakes. Port side looks pretty good but the starboard side has minor damage to the prop. It must be from sucking up small rocks off the bottom.

 

[Tailwaters]

That certainly could be your problem

So I checked the props and they had nothing wrapped around them.
I did a GPS check with my phone we where traveling at 35mph.

I did notice that my RPM maxed out at around 7300/7500.
Do you guys hit the 8000 RPM mark?

Thanks for all the feed back on my questions.
maybe I can buy you a beer someday.

Just curious if you found your issue?

Thanks,
