    Mercury Outboard 850 thrust washer behind reverse gear seems loose/too much play

    Rebuilding my Merc 85hp's gearbox and the reverse gear thrust washer seems to have more play than 'normal'(?). I'm concerned that it won't hold the o-ring proud enough for a positive seal, since it presses the ring back against a sloped surface that forces it out against the inside of the case...

    '68 40hp Johnson Hydroelectric shifting strangely

    While testing the gearbox on a 68 Johnson electric shift I found that when I put 12v to on wire it would shift into fwd gear, 12v to the other wire put her in reverse, no voltage to either would give me neutral-- and 12v to both wires would lock the gearbox. Something seems to be working, just...

    Firestone Scott Atwater 3.6 hp model 10a51 1949 water cooled? Impeller probs?

    I just got a Atwater 3.6 motor from a bud's garage and was wondering if these things are water cooled. In vids I've seen similar models spitting water from the back center of the exhaust housing. From other vids it appears that if there was an impeller, it would be located under the motor in the...

    mid-70s? 6hp Johnson no spark bottom cyl. -- where to start?

    '93 Force 90hp Kill switch wire question (no spark)- black/yellow seems to be grounding somewhere...

I ran some tests on the wiring and found that the black/yellow (from kill switch) seems to be grounded regardless of kill switch position/status. Just to make sure I have this right...

    85hp V4 1974 Johnson- new throttle cable, made some adjustments, trouble starting/running

    So I think I might have gummed up the timing on my motor, or maybe the idle throttle- I don't know. Three days ago she started up without any trouble, and ran like a top. Compression is perfect, solid spark on all four. What happened was I was having trouble getting the throttle up to wide...

    Years of work, engine won't run. Running out of options and about ready to sell.

    72 Evinrude 50hp Lark, 50273c I've been working on the damned engine for years and it just refuses to run right (or maybe I refuse to fix it right, anyway..). The previous signs were low power output, poor fuel economy, and intermittent hard starting. Recently I discovered a crack in the fuel...
