    Can I use MMO as a top end cleaner??

    I'm going to decarb my engine this week along with many other things to try to get her to stop spitting fuel out one of the carb throats but while reading other messages here, the subject of stuck rings came up. I know on 4-stroke engines, we would pour some Marvel Mistery Oil in the plug hole...

    1985 90hp dead cylinder

    Hello again. While trying to figure out why my engine won't accelerate past half throttle, I pulled the plugs and noticed that the #1 spark plug came out clean as a new plug. Since the engine has been run and there is no fuel/oil on the plug, I have to assume that there is no fuel getting into...

    1985 90hp Evinrude bogs above half throttle

    I have a 1985 Evinrude 90hp engine that when I started it yesterday ran find and was running at 3/4 throttle for about 15 minutes when it suddenly bogged down and from then on it will run terrible above half throttle. Initially, pushing the key in (activating the choke) would allow the boat to...

    Powerhead identification

    I know the question of what year/hp an outboard is has been answered hundreds of times and I've determined from the model number that I have a 1985 Evinrude 90hp. My question is whether or not there is a way to identify the powerhead to see if it matches the numbers of the transom bracket??<br...

    Scored sleeve... Need to know why.

    Hello again. I am disassembling the powerhead in my 1981 Evinrude 115 because one of the cylinders (number 2) is scored and I'm trying to figure out why this happened. The rings are in tact (not broken) which leads me to believe that there was either debris in the cylinder or that it was...

    New rings... Old engine??

    My 1981 115hp Evinrude is in need of new rings and one new sleeve. Is this procedure any more complex than putting new rings and sleeves in a 2-stroke dirtbike?? The reason I ask is because I was told today by a marina that I'm better off buying a rebuilt power head than putting new rings in...

    1981 Evinrude 115hp won't start... again

    You guys were a great help several months ago when I was originally trying to get this engine running after about 5 years sitting idle. Since I got it running back then (April I think) it hasn't been started and when I tried starting it today, it won't start. <br /><br />I have fuel coming out...

    adding hydraulics to Evinrude 115hp

    I have the hydraulic tilt/trim unit to add to my 1981 Evinrude 115 but it appears to be missing a hose of some kind. You can kinda see it on the left side of the attached image. What I need to know is what ends are on the hose so I can have one made or if it has a name or part number so I can...

    Straightening a bent frame

    I know that it's possible to straighten a bent frame but can it be done safely?? Also, what is the best way to do it?? Heat it and straighten it or cut away the bent section and weld in new steel??<br /><br />Any help is apreciated.

    '81 115 Starter and charge coil

    Hello,<br /><br />I have a 1981 Evinrude 115hp outboard that I believe has a bad starter because it draws over 100amps from my battery charger and spins the engine very slowly. I ran the charge coil output test with this starter and it registered very low (65volts max) and I'm wondering if this...
