Check the Mercathode system for power. Fused (20A) off the starter usually. Corrosion is likely from an underwater electrical leak nearby. Not likely corrosion from just being in the water at LOTO.

Had a nice test run this weekend. It was windy out tossing the bow of the boat around trying to maneuver in the marina, but once we got out on the open water it was perfect.
It appears one of my light blue butterfly caps on my CMI headers is leaking, but other than that, no issues to report before coming to LOTO this weekend.
Quick vid of her running this weekend.

Had ourselves a renaming ceremony at LOTO this weekend the last D got a little wonky when i trimmed it to fit over a snap for our cover. The boat ran great all weekend, only caught air once and the truck did a great job towing in back and forth. Looking forward to summer!

A friend of mine Brad Harrington is going to get out on the water with me to make sure I am driving the boat correctly. I cant seem to get over 68 MPH even with a light load. I talked to the previous owner and he stated he wasnt able to either, and he bought this boat brand new.
Thinking about purchasing a scan tool to check the engine out and see what RPM ranges were hit throughout its life. I am wondering if my RPM gauge is off or potentially the throttle body is not adjusted properly and it isnt opening all of the way. With the previous owner buying it new, I would have to think something was wrong from the factory, but who knows. I tried to contact Fountain to get the test slip and didnt get a response back. Of coarse this would just be me being an inexperienced boat driver and I am doing something wrong.
The plan is to run at the shootout, maybe go out a couple more times with the kids then pull the engine to rebuild the top end. Doing a full top end rebuild and not just springs and rockers.
There is another thread on the forum where the guy was down on power and it was a bad injector, just got me thinking. Let me know if anyone has any ideas, or if anyone has a scan tool that they could bring to the shootout if they are coming. I bought a slip at captain rons and will be down there from Tuesday the 22nd to Monday the 29th.

What prop/ rpm/ drive ratio? Also on trailer make sure you know where neutral is on drive tabs so you know for sure how much you are trimming it.

I am able to hit about 4900-5000 without trimming the drive, once I start trimming I have seen 5200 on the gauge.
Its a Bravo XR so should be 1.50 ratio, I have not taken anything apart to confirm for sure.
I typically get on plane and without any drive trim get to 60-62 MPH. Then I will start trimming until I start shaving off speed and cant seem to get anything over 68.

so what do you think it should be running ? 5200 @ 68 with that prop might be all it has, I think the limiter is set @ 5350 on that engine
