Hi All,
New to the forums here, looked around a bit and this seemed like a perfect place to ask!
I have a 1992 15 hp Evinrude that I purchased last fall. I've been having issues with it bogging down under load, but it happens sporadically. It's happened several times now where I launch, I run upriver for about a half hour with WOT and it runs fantastic. I usually fish for awhile, and while running back down, the engine starts to bog down under WOT. If i back the throttle off the motor stops bogging down, but when I increase throttle again, it bogs once more. Sometimes it dies at this point if I keep the throttle going, and sometimes I can back it off so it just idles. If i shut off the engine and let it sit for about a minute or two, I can restart and get another five min of good running at WOT or so before the whole process repeats itself. Priming the fuel bulb while its bogging downg (sometimes) helps and RPMs increase. (and sometimes doesn't).
I know some basics about 2 strokes, and this is a list of what I've done to the motor so far in order of how I've done them.
-New fuel lines/primer bulb/fittings
-Put new ethanol free gas in tank w/ 50:1 oil mix
-Compression test. Both cylinders at 125/127
-new spark plugs
-spark test. Jumps gap correctly.
-New fuel pump
-Pulled off the carb and did a complete teardown and cleaned all fittings and jets and put new seals in it
-Did a "lync and sync" to adjust timing of butterflies on the carb in relation to throttle
-Adjusted fuel/air mixture and adjusted idle speed to optimum.
So as you can see, I've tried a few things, but am still having the same issue. I should mention that so far since owning this outboard, I've only run it in cold water (32-35 deg) since I live in MI. Not sure if this plays into it at all, but I am curious to see what happens when the weather/water warms up.
Is there anything I'm missing here or any thing else I could try? Anything obvious that I may have missed?
Thanks in advance!
