Oil injection was removed and it's got the enrichner. It's a mid 80's merc.

Good point Ferm, If it bogs down the engine when you push in the key switch, then you know its not fuel, if it doesn't do anything, it could still be fuel, your not getting it to the enrichener as well as the carbs. If it picks up when you hit the enrichener, then you know its down stream of the enrichener

Ok I took the filter off and there was no water at all!!

BUT what I did find was a bunch of metal shavings??? When I say a bunch ity was not loaded but there were more then just a few pieces, and how much was stuck in the filter I have no idea??

I am waiting for a friend right now and we are going to take it for a ride.

But with metal shavings in the plastic bowl that you drain, do you think it got to the motor or fuel pump, and carbs??

not sure how these filters work?

How'd you get metal shavings in your gas?

Well I took the boat for a long ride and still have the same issue t times??

Quote:

then push the key in to chole the motor, if it picks up, you have a fuel issue between the fuel line and the intake, if it bogs down when you push in the key switch, it sounds electrical

when I pushed the key in, it bogs down and stalls if I hold it there long enough??

I am also still worried about how hot this thing is?? Even at a 7 miletun at 4500 rpm's as soon as you slow down seconds after there is steam coming out?

Did I say I love Merc's yet today

The steam isn't a big deal MJ, get a temp guage and check it. Anything under 170 is pretty well normal for a MERC at low RPM's. Even my EVINRUDE in 65 degree temps will have alot of steam coming off the water from the piss tube. Sounds like you need to get BS over for a ride though.

Have you had the cowlings off of the engine yet? Check it for any restrions or such in the cowling or by the carbs. You may have an air blockage to the engine causing it to run rich since you said pushing the choke bogged it down. Theres also a chance you have some trash caught in one of your needle and seats causing this since all of the debris you mentioned in your filter. How do the plugs in it look? Try running it in the water under load and shut it down while your running on plane. Then go back and pull the plugs out. This will help you to figure out if you have a cylinder loading up or not.

what exactly did it do today, leave the temp issues out of the description( I agree with Ferm, doesn't sound liek anything is wrong there). it doean't sound like its runnig rich, sound more like an intermittant ignition issue, but with out running it myself, it would be hard to tell

After finding the metal shavings in the filter I was thinking this was the problem? So I drained the gas from the filter to see if there was any water, there was none.

Took it for a ride, started right up, and we idled out of the harbor. Got pass the no wake area and opened her up, she went fine for like 2 mikles or so. Then I could feel her sputter a little and lose rpm's
At first I was thinking that maybe the shifter was backing down its self, but that was not the case.
drove out about 6 miles and it was sputtering on and off the hole way. Got out to a light house were some guys were fishing for tog, shut her down while I asked how the fishing was, They said it sucked and I wasn't missing anything!

So I started her up and she was on like a light switch and off we went. after about 1 mile we started the process all over again?? Then I remembered about the key switch, so I pushed it in and it got worse, I held a little long at one point and stalled the motor.
Started her right up and came the rest of the way sputtering all the way.

It would go again for a few seconds then it would start breaking up again, after a few min it would go good again then replete.

Thanks guys
