Anyway.... as soon as it goes to WOT, a check engine light comes on and there's a warning beep.

It's a 1998 Evinrude 150.

Quick internet search suggests likely fuel restriction problem - fuel line, filter, etc.

I've only had it out a handful of times in the last 6 months - 3 of which ended quickly. So the boat hasn't been run a ton lately.

I know there are a bunch of knowledgeable folks out there (of which I am not one) who may have some suggestions.

(My brother borrowed the boat and I wasn't on it, so this description is from him).

Ok, so here is what happened. Picked the boat up filled the oil injection tank but was not sure how much gas was in the tank, so I stopped on the way to the lake and got gas. I prepayed for $20 just to make sure there was enough for the little bit of running I was going to do. The boat, as it turns out, was almost full and I ended up completely topping it off.

Launched the boat and it took a few tries to get it started (not all that uncommon). Once it fired, it ran great idle out of the Marina. It is about a 3min idle out of the "no wake". When we got it out of the no wake, I put the boat up on plane and as soon as the RPMs settled out there was a constant tone, not a broken beeping. I looked at the warning light panel near the ignition and the light by "Check Engine" was illuminated. I then took it back off of plane and the tone stopped and the light went away. At this point, I thought it may have been a fluke so I put it back up on plane. Same thing.

There are 4 lights on the warning panel 1)No Oil 2)Engine Temp 3)Check Engine 4)Low Oil. It was the Check Engine the was lit

The water pump was working fine

The engine has a carb, so I doubt it has a computer.
