Check Engine Light and Warning sound at WOT

[know1]

So third trip in a row with a mechanical problem on my boat. This is getting old.

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).

[Embrey]

describe the warning beep...constant? or fast beeping? etc

[know1]

He described it as a beeping.

Is to oil injected? If so maybe. What is WOT?
Constant beep. Over heat
Beep every minute. Low ingection oil
Beep every 3 seconds. No injection oil

Not anything close to a mechanic but that is what it is on an 87 Johnson. If it's constant check the water telltale and make sure there is a water spraying out of the engine.

If it's not getting fuel check the connections on the lines to the tank and motor and the pump bulb. This sounds simple. I had both of the above cause my motor to cut out ay high rpm and not start because somebody put a cheap hose and bulbs on. Replaced with 60 dollar Johnson parts and everything is OK.

Thanks for the advice so far.

I wasn't on the boat this time, but here's what he told me:

He launched it, idled through the no wake, took off and as soon as it was on plane the light came on and the beeping started (I'll need to check with him as to the frequency). He brought it off plane and the light turned off and beeping stopped.

Put it back up on plane and it immediately started again. Brought it down and it stopped again.

He idled back and trailored it.

He told me that it wasn't overheating, but I'm not sure how he knows except by the gauge, I guess.

It is oil injected and there was plenty of oil. I know that doesn't mean the injector was working. With my very limited knowledge, I immediately assumed it was the oil injector, but wondered why it would stop when it was idling.

I guess it was misleading to me to say WOT.

I am not really for sure about the 98 model Evinrude 150's but I do know the 99 150's have a computer that store any alarm code that is tripped. Evinrude started using a computer on the early Ficht/direct injection motors so if it is a Ficht it will have a computer that stored a code fault to the alarm. If it is carburated it will not have a computer. If your boat does have a computer you will have to take it to a dealer to access the codes or buy the cable and software and do it from a laptop computer at home.

I am far from being a mechanic but my guess would be moisture in the fuel. If it has set for a long period of time I would drain the tank and try to dry it out. Then I would install a new fuel filter and add fresh fuel. That may not be your problem but that is something not so expensive that you can do yourself without taking it to a dealer any paying big $ for them to work on it. Plus the fuel filter needs to be changed on a regular basis anyways.

If you have water in the fuel at idle it is not using enough gas to pull the moisture that has settled in the filter or tank. When you drop the hammer then it will pull up the moisture and trip an alarm...like I said this may or may not be your problem but the symptoms sound like it is possible.

[know1]

If it is moisture, does the tank have to be drained or can I just add a fuel stabilizer, more fuel and change the filter? There's probably $80 worth of gas in the tank at this point.

It's been used about once per month for the last 10 months.

I REALLY appreciate the advice from everyone.

If it was me I would let the boat sit long enough to ensure that any moistire has settled to the bottom(couple days?) and drain the tank. Most all of the moisture should settle to the bottom because water is heavier than gas. I would drain 90-95% of the tank and run it in my vehicle. The other 5-10% I would drain and use to burn a brush pile or get rid of. If the tank was easy to access, I would remove it and clean it dry. My friend cleaned moisture out of his tank one time buy draining all fuel, then removing the fuel intake and ran a piece of pvc with a rag attached to the end to dry out the bottom of the tank.

If that is not an option, I would drain as much as possible and change the fuel filter, then add NON ethanol fuel and see what happens.

You said your motor was a 98 150...is it a Intruder or a Ficht?

It's an intruder, but now I'm doubting my memory of the year. It might possibly be a 96.

[CTFSHWHISKER]

if it is a 98 it can be either a dfi ficht,or carbed motor,even the dfi motors has intruder decals on them,so you will need to see which it is,96 would be carbed only.
1 check oil tank level,if it is close to low it will trip the low oil alarm when you take off,it will shut off once you get going and oil levels out,fill up tank.
2 if it is a fuel restriction,very good chance you have a bad anti siphon valve,in the fitting on the tank where the fuel line connects,remove fitting knock out ball and re install.notorious for tripping high rpm alram,usually 3500+ rpm and up.to get a portable tank,fill it and hook it to your motor,and run it.be sure to plug the line coming from the boat mounted tank.this is what i'm betting you will find.
3 while your in there check all fuel ine and oil line connections for seepage where they clamp.signs of places to suuck air in.
4 you should have the system check warning system,the gauge should indicate,low oil,no oil,in the tank only,over heat.check engine,it indicates fuel restriction if it's lit.
if not done recently i would change the fuel filter,add a water seperator and check your fuel lines for deterioration.as stated in the earlier post,if it is a ficht it will have the codes stored in the computer,you will need to take it and have them read at a dealer,1st thing then go from there.

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.

[Embrey]

just cause its peeing doesnt mean its working fine always. any idea what water pressure was? pressure could be down due to worn pump causing overheat issue. if its been over 2 years, it should be changed anyways regardless.
