    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...

    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...

    8hp Evinrude running poorly.

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

    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

    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.

    100:1 or 50:1?

    Not that it matters but that is an 1988 not a 1989. Your knob is still missing, did you plug all the lines coming and going from the primer? Those were excellent running motors but if you have bad compression or bad spark or fuel issues it's not going to run.

    100:1 or 50:1?

    That's a lot of questions. When transporting, you can set it anyway you want. Take a picture of the front and the id tag and post.

    6hp evinrude compression?

    100 or better. Seen them run at 90 or so and I purchased a late 80s one once and it tested at 140....basically new. Hopefully there fairly even.

    96 150 Faststrike puzzler..

    Probably limp mode or slow mode from a failed temp sensor or it's over heating. Lots of posts on this so you should get more opinions. Brown wire on the port side temp sensor sends the signal to go into limp/slow/safe mode. Posts say to unhook brown wire and test but you should make sure it's...

    2000 Johnson 15hp wont pump water

    Well if you had it at professional mechanics like you said and they couldn't figure it out then pretty sure no one on here can. Sorry I couldn't help.

    100:1 or 50:1?

    Scott, you would have to re-read the very long post (and he has two posts for the same motor and issue)and look at what he's done. Sometimes he could start his motor at home but not the marina. He didn't know what a primer was and pulled the plunger completely out and lost it. To top of off...
