    1988 260 timing and idle variance

    Just replaced several parts including shutters, cap, rotor, plugs, ignition pickup module in the distributor, coil wire etc. The boat runs great, smooth, starts easy perfect temps, oil pressure etc. I noticed I am still about 2-3 mph slower than I was a year or so ago. I thought the tune...

    Help! I'm running out of parts to throw at it...!

    1985 Merc 90 inline6. Started running bad - missing fouling plugs. I rebuilt the carbs, replaced trigger, replaced both ign boxes with new cdi, new rectifier. Still runs like poo. If I disconnect the rectifier, it runs great and goes like a scalded dog - better than if ever has in my...

    Can anyone tell me if the LU from a 73' Evinrude 135 will work on a 78' Johnson 115 ?

    Hammering sound when I turn under power... ?

    Pulled the drive (2 year old complete new gen 1 alpha 1 SEI) Expecting to find bad u-joints or gimble bearing. Everything is clean, bearing is smooth as glass, zero noise. U-joints also feel great, I can't detect any notchyness or play at all by hand - very smooth and free, almost floppy...

    1985 Merc 90 (inline 6) trouble shooting help needed

    While out on the lake last week (boat running fine to this point) while throttling up (punched it) the engine "seemed" to foul a plug. Changed plugs, no difference. Carbs were wet, so I ordered some kits and replaced the needle-seat and cleaned them. (Though, they were ridiculously clean to...

    1978 140 hp

    Looking at a 78' 140 hp outboard. Sounds like it runs good, pumps water etc. Just wondering about these engines, I have zero experience with Chrysler OB's (but somewhat drawn to this since I'm a Mopar guy in the automotive world.) Had several Mercs and a few Evinrudes ... Is this a decent...

    73' 135 Issues, what should I check next?

    Recent purchase, 1973 135 on a Marlin Gemini. Engine looks great, doesn't appear to have been abused, never torn down except carbs. (Sat for almost 20 years in storage I'm told.) Carbs were supposedly cleaned and synched jsut before I bought it. I replaced the seals in the LU, and the water...
