    1984 40hp Evinrude, shut down suddenly, now no spark

    The motor was running fine. While cruising along at about 80% throttle it suddenly dropped the RPMS by at least 50%. I throttled back and it ran OK for maybe 10 seconds until I tried throttling back up. It sputtered a bit and shut down completely and would not start. Got in on my spare. Back in...

    1984 40HP evin. manual tilt problem

    Tilting the motor (manual) is getting very difficult. I've greased everything in sight. The one thing I'm starting to suspect is the center tube where the steering cable goes through. One of the grease fittings there will not take grease. It's not the fitting itself, because I've taken it off...

    spark plug wire popping off

    1984 40HP Evinrude. Strange problem. Twice in the last three times out I've suddenly dropped to one cylinder and when I opened the cover I found that a spark plug wire popped off a spark plug. Top cylinder first time, bottom today. Reconnect and all is well. What could be causing this?

    cooling problem solved, lessons learned

    Despite good flow out the telltale on a 1984 40 HP Evinrude, the engine was not cooling properly. I had no cooling water exiting anywhere else and my temperature warning alarm went off. Given that this is a salt water motor that sat all winter and most of last season, I suspected and changed the...

    flushing through water tube

    I'm having cooling problems with a 1984 40HP Evinrude. I have good flow out the telltale, but I get barely a trickle out the prop hub, and if I run the motor at just above idle for more than 10 minutes, the temperature alarm will go off. I've changed the thermostat, but this didn't correct the...

    pressure relief question

    I've removed the water cover on my 1984 40hp Evinrude electric. Above the thermostat is a red plastic thing on a spring that the manual has labeled as a relief valve. Can someone explain how that functions?<br />My understanding is that it functions when the engine is run at higher speeds. I can...

    re-installing bolts

    I hope to be re-installing water cover bolts on my 40hp evinrude soon. They're no fun removing. What's the best product to use for reinstalling the bolts so that they'll come<br />out easier the next time. I've searched the site and seen references for "anti-seize" but some concern that<br...

    removing tight bolts

    I need to remove the water cover on my 1984 40HP <br />Evinrude Electric so I can change my thermostat.<br />A couple of the bolts near the bottom of the block<br />seem like they're going to take some effort to remove.<br />They're hard to reach, so I can't tap them with a hammer. <br />I've...

    40HP Evin. Cooling Question

    I recently bought a 1984 40HP Evinrude Elec. It pumps like crazy out the telltale. I'm a little concerned because I don't see water coming out anyplace else. I thought it would come out through the prop like a 35 I once had. I only ran it at idle for a couple minutes. The water coming out the...
