87 Mercury Classic 50 wonbt throttle past 3000 RPM

"Bought a 1987 Bass Tracker with an '87 45 HP Mercury on it. Floats were stuck, so I had to have both carbs rebuilt. Took it out for the first time this evening. Went right up on plane, and I was running 5,000 RPM at WOT (about 30 MPH). All of a sudden, the motor bogged down, and died. Started right back up, but now won't throttle past 3,000 RPM in gear and won't plane out. In neutral, it is fine...throttles right up.

I pulled all the plugs and looked at them when I got home. The only one that was dry was the bottom one. Other 3 were wet w/ fuel and had a little black sludge pooled in them. Hard to really tell because the plugs are brand new. One other thing...my 6 gallon tank only had about 1/2 gallon of gas left in it. I was only out for about 1 hour, and 30 minutes of that was idling back to the ramp. Seems like it's pulling a lot of gas. Also, the bulb was soft when I got it home.

Photos of my plugs can be seen at the following addresses:

I suspect you need a new fuel pump kit installed. The bulb should always be soft when the motor is running.

"if we both pulled plugs and see fuel pooling dont u think were smart enough to check for spark, ya know since ive been on this forum , ive been given one helpfull idea other than that its been a place for me to type my frustrations, i built a escort cosworth and got a engine from japan and had no idea how to install a standalone fuel management system to stock wire harness, got on feoa.net auto forum within two hour i had over ten replies, and any other questions i had everyone had some kind of answer, or an idea something, i mean two heads r better than one,give us some answers jezzzzz"

"tim. have had a few ideas fro

"tim. have had a few ideas from a couple other forums. i am going to rebuild the fuel pump this weekend, and replace all of the fuel lines inside the motor. sounds like these old fuel lines start to break down and can plug the jets on the carbs. hopefully i don't have a bunch of gunk in my carbs again. just had them rebuilt on saturday. i should have rebuilt the pump and replaced lines before rebuilding carbs. hindsight is 20/20 i guess.

the marine doctor suspects a faulty stator on the high side. might want to look into that as well. for some reason i'm thinking i've read that my stator doesn't have a high and low side. i'll need to look into that.

i'll keep you posted on progress. AC."

"ya u werent talking to me tha

"ya u werent talking to me thats y i have to find other simalar posts just to try and get some kind of answer d#ck, ac ,so today went to libray and got a manual what i should of done a week ago instead of wasting my time on this forum, dude i got new stator , triger ,retimed, fuelpump diaframe, carb rebuild , but i took the carbs off today and no new problems same as always but putem to facorty settings and runs like a dream but still having fuel build up on plugs after shut down,but of course ill have to figure that out on my own ,, but like with u i would take the carbs off and just go throughem there picky, junk merc, and i live in fond du lac where most r built"

tim: fuel buildup on plugs is

tim: fuel buildup on plugs is normal. nothing you have to worry about. found that out from another mechanic. don't worry about fixing anything else if it's running good.

"ya good to know, thanks man ,

"ya good to know, thanks man , but she stillwont start after 20 min of sitting untill i wipe them plugs off then it pops right off,confusing, and it ended up being a piece of rubber from the line in the needle seat hole that was effecting my top end proley from takenem on and off so many times."
