    8hp Evinrude running poorly.

    Careful with those bolts, they like to break off. Also, there is two parts under there so you will need two gaskets.

    1990 ish Evinrude 25 HP - Screeching from the controls

    High probability it's the pump but could be stuff inside starting to plug up....is it ran in saltwater? Also, could be a failing sensor but not likely. I wouldn't run it until you take a look at the pump, you wouldn't want to plug up your motor with bits and pieces of impeller creating a much...

    Flywheel is easy to spin without spark plugs

    Battery should be 12.7 volts or better. Also, you can have good volts but the battery can still be no good, hence the load test. You can take it to an automotive parts store and they can tell you but everything points to a low or poor battery issue. Motor is fine. Undervolting a starter by the...

    Fuel Pump Bad?

    Yes, center screw and you will find a screen inside. Most likely you will be able to re-seal but check seal. Good chance you will need to clean your carb as well.

    Alarm horn @ 4600 rpm

    Or spin the fuel filter out and dump it into a jar and inspect. Never know what gets pumped into your tank from the station.

    Fuel Pump Bad?

    Lol, yes I believe sometimes that's exactly what is needed. So the check valve is in the bulb....otherwise it would pump one direction (to the engine) the fix is a new bulb. But after thinking more, and Racer said it best, junk in the tank. If the draw tube gets filled with stuff the motor...

    Need electric start on my 30hp johnson

    I know the smaller motors better but omc had design changes between your motor (1990) and the other motor (1996) but it just a guess.

    Fuel Pump Bad?

    Or maybe the check valve in the bulb.

    Yamaha lf200 four strokes not planing out

    Seems pretty simple then. You or the mechanics need to go through the fuel system again. (Bad fuel) Unfortunate, buy it's what the evidence points to. I'm assuming after cleaning the tanks the main prime fuel filters were changed.

    8hp Evinrude running poorly.

    Boat is an issue but your right, might be something in the mid-range power. Or maybe not. As far as it shutting down coming down from higher R's? I believe that is because it's bogging down and not recuperating before you bring it to a slow idle. When I bomb around with mine, I slow down in...

    Oil mix ratio

    So there you have it....16 to 1 when they built it. Your call it looks like.

    I see your compression numbers so skip that. They look good.

    8hp Evinrude running poorly.

    I have a 92 that I bought in 92 brand new and it purrs like a kitten. I'm not sure about your meter but my ear says you idling about right. Pretty sure your bogging that thing down to much when you crank it up in the barrel...not made to do that. Big test tank maybe. The inflatable? Is it a...

    Have you tested it on a boat? Your revving it way to high in that barrel.

    Oil mix ratio

    Pretty sure it's 24 to 1 but you should plenty of opinions on this one.

    100:1 or 50:1?

    There is a little plastic clip that goes in the end of the tiller handel. It's also the kill switch. If that clip is in and you have good spark, then everything is working correctly. Parts 49c

    150 Johnson will not idle

    Yes, sounds electrical to me and might be challenging to find.

    Yamaha lf200 four strokes not planing out

    Did you buy them that way or did it just start happening? The most common thing of it happens to two motors at once would be fuel but you seem to have address that. What did your mechanics say?

    100:1 or 50:1?

    Retest compression with different tester.
