    Problem: Evinrude 120 hp (4cyl) 1994 outboard. Starts up great. Runs a bit rough at idle, coughs, but manages when cold. Runs great at high RPM. Very smooth. But after its warm, like running for 10-15 minutes at high RPM it won't idle. It starts runs a few seconds, then stalls. Sounds...

    Evinrude 120 hp loses cylinders and dies...why?

    This is a longshot maybe. But wondering if hearing the engine will help. It starts up fine. Fires on all cylinders usually, (not in the video though), then coughs, gets out of rhythm, then loses cylinders and slowly dies. Starts right back up and does this over and over. its a 1994 evinrude...

    Evinrude Carb Job gone bad?

    My 1993 or 94 Evinrude 120 HP engine was acting up on each start. It would crank over and start running then lose cylinders and finally stall. If I kept starting it, it would eventually run OK. SO I decided it was time to put in some new carb kits...especially since I knew one o-ring was...

    Rough Start

    I have a 1993 120 hp evinrude outboard. It required a lot of work to get it running a few years ago, but compression was good and it has run like a champ since. Lately though it starts up missing at least one cylinder. It runs rough for a bit before the others catch and then it usually runs...

    What engine do I have?

    My ID numbers are not on the engine mount. Is there another place to find them? I was told it was an evinrude 120 hp 1988, but the year may be wrong because I just ordered a starter that was supposed to fit (586283) and it doesn't. Thanks!

    Selling Merc 1400- where?

    I have a mercury 1400 that I gave up on. It has a broken crankshaft I think. I needed a quick fix and replaced it with another engine. Now I am trying to sell it for parts or as a project engine. It was in good working shape until the shaft broke. I also have a bunch of spare parts like...

    1400 Wire harness compatible with 1500

    I am trying to sell parts off my merc 1400 (1978) I6. One buyer wants to know if the wiring harness and throttle would be compatible on his 1500. He has power trim and I do not, but he says he doesn't plan on using power trim anyway. Is the plug compatible? thanks

    Leaking Carburetor in 1988 Evinrude 120

    I just cleaned all 4 of my carbs. The last one I did, I can't seem to get to stop leaking. It is the only one that I took the seat (below the needle) out. I don't know if there is a specification for how to put the seat back in. I thought maybe I had tightened it too much, so I took it apart...

    Hooking up Tach

    I am trying to get a tach from my old mercury engine to work on the newly installed evinrude 120hp (1988-v4). I believe it should work. Problem is the previous owner played with the wires a bit, so it is hard to know if things are hooked up properly. I read 24 volts AC across the A and B...

    Coughing 1988 120 hp evinrude

    I just relpaced my old mercury engine with an evinrude 120hp (1988). I had it running pretty well on a stand and now that it is hanging on my transom it is running poorly! Here are the symptoms: 1) At idle (on the hose) it coughs fairly regularly and almost stalls and then recovers itself...

    Is crankshaft too loose? - Videos

    I have been posting on my merc 1400 (L6) that had a thumping noise in the powerhead. I have followed up on a suggestion from chris to pull the flywheel off and look at the upper ball bearings of the crankshaft. I have done that and it looks like they are intact, but they seem to rotate off-...

    How much does a 1988 evinrude 120 weigh?

    I am doing an engine swap from a 1978 merc 1400 (L6) to a 1988 evinrude 120 (V4). Does anyone know how much either of these weigh? I don't want too much more stern weight and the evinrude looks a good bit bigger. They both fit a 21" transom. I have found it very difficult to find this...
