    2005 Johnson 115 minor annoyance this time

    That works fine on a trailer, but I can't hear trim motor over the engine on the water.

    Heh, that would explain why manual is silent on the subject..

    2005 Johnson 115 minor annoyance this time

    When I trim the engine in, engine comes to a stop, but the trim motor keeps running until I release the button. Faulty switch? Where do I look for it? Come to think about it, the boat did not come with a trim angle gauge. Is there a way to hook up an aftermarket one? I suspect the sender is...

    2005 Johnson 115 with low compression: noob seeking wisdom

    MMVZ 3.115 Minsk. But that was an early 80s motorcycle I was playing with in high school. Previous 2 stroke outboard was a 15 hp Mercury (on a different boat), not a drop of oil. Looks like I found my problem, though, you were right about the carb. Scum is down to believable level, a lot less...

    2005 Johnson 115 with low compression: noob seeking wisdom

    That much I know, but back in my days they didn't have reeds. :) My previous 2 stroke outboard did not make this kind of mess, either.

    2005 Johnson 115 with low compression: noob seeking wisdom

    Yep. Nothing obvious, except that the bulb doesn't go quite as firm as I thought it should, but if I tilt the engine, gas comes out of bottom port carb throat. Looks like a float valve to me. Let's see where I screwed up on rebuild...

    Last December. Replaced warped bowls and maintenance items. Primer bulb replaced with OEM around the same time.

    2005 Johnson 115 with low compression: noob seeking wisdom

    I probably don't - still learning. That's why I'm here. Not that I want to mess with them if I don't have to. What else is possible? Carb flooding? Fuel pump diaphragm leaking? Thanks!

    2005 Johnson 115 with low compression: noob seeking wisdom

    Way too much even for a two-stroke, IMO. Any thoughts on what should I check to see if it is normal/not normal? Thanks!

    2005 Johnson 115 with low compression: noob seeking wisdom

    True, but I am hearing they could cause trouble with raw gas/oil in exhaust, which was my problem in the first place. Not that I know much about two-strokes; haven't messed with them since high school.

    2005 Johnson 115 with low compression: noob seeking wisdom

    On the muffs, oily scum floats on top of cooling water, and a few minutes later a good size loogie comes out (couple of tablespoons, maybe more, stinks like gas); lots more than one would expect even from a two-stroke. Bad fuel economy even for an engine this size. Bad smell of gas, with no...

    2005 Johnson 115 with low compression: noob seeking wisdom

    Thanks, that's what I was thinking. If the compression were all over the place, I would have been a lot more worried. The only reason I started messing with it is because of snot in exhaust (and lousy fuel economy), but I think I narrowed it down to reeds.

    2005 Johnson 115 with low compression: noob seeking wisdom

    Here is that 2005 2-stroke 115hp Johnson (PLSOR) that I am goofing around with. Compression seems consistently low (90 psi +/- in all 4 cylinders), but starts/idles/runs OK. Any thoughts on how to proceed? Leave it be and deal with it when real trouble starts? Tear down and rebuild now...
