I'm selling my Mercury outboard 15 hp motor and need to know what year the motor is. All I can find is the serial number of A197124. I am pretty sure it's an early 2000's but want to be sure as to not deceive the buyer. I have looked and looked online to see if I can find out any info on the...
It's my own fault but after winterizing my '76 85hp Johnson motor, I took it out one more time in December because it was warm enough to and forgot to run the gas out, pull plugs etc.. Now it's having difficulty starting go figure. After spraying WD40 in the air intake it started but putterred...
85 horsepower Johnson 1976. The high speed jets in the carbs were damaged so I replaced just the bottom bowls where the high speed jets are located from an exact pair of used carbs from a scrap motor. Now when I turn the engine on the idle rpms are way too high. So high that I am unable to...
I have a 1976 Johnson 85hp outboard and it is having issues getting to top speed at WOT. It should be going 40 which was normal but lately it will randomly drop to 26 mph and then after more riding around drop to 10 mph and not sure the cause. It's highly frustrating. The motor runs smooth...
I have a 1976 Johnson 85 hp outboard. The problem I'm having is that the motor will be running fine and then it will sometimes, rather spasmodically will drop 2 cylinders and run on 2 cylinders. My manual says that if it runs on 2 cylinders all the time it most likely will be the sensor coils...
Hey guys. I was wondering if these symptoms sound like a bad coil/coils. The mechanic just called and told me that my 1976 Johnson 85 hp was running great and that he was done with it. Then he called right back and said it started running on only 2 cylinders for the first time ever... He...
Hey guys and gals. I have a problem that nobody seems to be able to answer for me. My 1976 85hp Johnson seahorse is a great motor that has not given me too many problems at all. Unfortunately now on my first trip to the lake after taking it to get tuned up at a marina (probably my first...
On the lake right now, the boat was running great at WOT when suddenly the motor jumped out of the water and throttled all the way down. Propeller didn't hit anything I think it just jumped out of the water bc it throttled down so rapidly. Boat will not crank back up but is turning over and I'm...
Usually when I post on here, I'm asking for help because my 76 Johnson 85hp isn't running properly and I'm trying to figure out what's wrong. . . This time though I have a question about how it got running so good. I had tuned up a new motor that I bought and tuned and tested just about...
I just bought a 76 johnson 85 hp and can't get full WOT and noticed that the ignition advance pin, ( I guess that's what it's called ) about an inch below the fly wheel (runs parallel to the ground) that can be screwed in or out to control the firing and timing of the motor at WOT (I've been...
Hey folks,
I just bought a '76 85 hp Johnson and the guy had a new solenoid and starter on the engine. The first thing I noticed was that the new solenoid was not the right one for this motor. I have had it 3 weeks and been running it at home fine tuning it to get it ready for the water, when...
Hey,
I'm a novice at outboard repair but am learning. I have a 1976 Johnson Seahorse 85 hp. Does anybody know if rebuilding the carbs on this motor is the same process that "Tashasdaddy" mentioned under Engine frequently asked questions??? And if so what is the special tool that I need and...
Hey,
I just installed a 1976 V4 85 hp Johnson Seahorse on my 16ft aluminum Vhull 1971 Starcraft. I am having real problems with adjusting the throttles though and getting them to where it will run with full power with the throttle wide open. It's as if I am having to fight with the control box...
Hey guys! I just bought a 1976 Johnson Seahorse as a replacement motor. I just installed it. It trottles up real well and sounds good but the one problem that I can detect with it is that it misfires and sputters (sometimes cutting off) when it is throttled down all the way in neutral... I...
