    85' 90HP evinrude doesn't rev over 3,000 rpm's

    1985 Evinrude 90 hp E90TLCOS
    My outboard seems to not like running while once warmed up.
    So for the rest of spring and summer I never had an issue with the engine at all until last September while at Leech Lake in Minnesota with my dad and brothers. One evening I was just cruising around at 30 mph and the motor started to lose power and came off plane and went right back down into the water and wouldn't rev up again. I could get it up to 3,000 rpm range again but not any higher . All I could do was head back to the cabin with the bow straight up in the air at full throttle because it wouldn't go over the 3,000 hump and take off and plane out. So next morning I went to a marina in Walker and bought new plugs and fuel filter knowing damn well this wouldn't fix it but the old people I was with insisted that I should try it. So it fired up and after 3 attempts at full throttle it finally went on plane and the tach hit 5,000 rpm's. Headed back in, ate breakfast and then headed out for a day of perch fishing. This was very short lived though. Not more than 15 minutes after heading out across the harbor to go fishing it lost rpm's again. So I tried starting and re-starting and full throttling the engine several times just for the hec of it with no avail. All this got me was a messed up bendix on my starter. Man was it jacked up, the teeth were all but gone. I had to use my trolling motor the rest of the way back to the resort and call it
    a day.

    Once back home I took it to my mechanic to have the steering looked at as well as the rpm issue. The steering cables and whatever it is that goes under the dash were all replaced. However the shop couldn't get the motor to not rev up. Granted they only had it in a tank but he did say they let run for 45 minutes and got it hot but it purred just fine. Who knows?! Got home and took it to the Rock River to make sure it would run alright before my last bass tournament. Here's how that little test run went. Loaded in the river and headed up stream....took off just fine and drove it around 4,200 rpm's all the way up stream for a good 10-15 minutes. As I turned around and headed back down stream and punched it....boom, only could get to about 3,000 rpm's again. Lucky for me I had the current to help
    get me back or it would have took forever.
    So the boat is somewhat stored behind my garage waiting for spring to come around. What sucks is not knowing whats wrong with it and that no one I have talked to has any ideas, not my regular mechanic, not Anglers Edge or Jerrys Sport service in Beloit. My conclusion is that this issue it has now only occurs after the engine is hot and under load. I have considered ordering 2 used power packs from Minnesota and praying for the best but no one else seems to think that could cause it.
    What your first thought? If I could afford a new engine I would but that
    isn't going to happen. Any ideas?

    well I am glad I got so many replies. Not sure what I did wrong.

    Anyways I got it fixed. It was a solenoid. Yep that simple, I kept dropping a cylinder when it would warm up to operating tempature.

    As of your last post on the 17th you were taking it to the shop. No need for us to get involved once it is in the hands of a trained mechanic.
