    '95 Twin Johnson 175's

    I have a pair of subject motors. They have decent compression across all 12 cylinders, 95-105. Thermostats replaced last spring along w/ rebuilding all 12 carbs and new plugs. VRO's are still in use. For the most part the motors run well except the port shows an oily residue at the...

    Decarb

    Would it be a good time to decarb right before winter storage? Planning on pulling the boat next Saturday for winter storage. Was thinking of decarbing the night before, let it sit overnight and then give them (Twin '95 Johnson 175's) a good run before pulling the boat on Saturday. Plan on...

    Exhaust Discharge

    I have twin '95 175 Johnsons. Both engines run well, start well, idle well, reach ~5200RPM. VRO's are still in use. The port engine has a discharge coming out of the exhaust.......see pic below. Seems to smoke more than the stb motor.........didn't think much of it until I noticed this...

    Yamaha ox66's

    I have been doing some research in purchasing early 2000 ox66 200's to replace my aging/thirsty '95 175 Johnsons. Looking for twin set-ups ultimately. I'm finding that the general consensus is that these are GREAT motors and the only time they seem to come up for sale is when one has "1 down...

    '95 Johnson 175 Replacements

    Probably gonna open up a can of worms here........... I currently have a pair of '95 Johnson 175's, powerful but thirsty engines. Beginning to investigate what I would replace these motors with. I'm limited to 400HP total and the weight of 4-strokes would be too much, not to mention the cost...

    '95 Johnson 175

    Have twin '95 175 Johnsons. When trolling 1 engine seems to "load-up" and start to sputter and smoke more while in gear. if I shift into neutral the idle rpms shoot to ~2K.......and eventually "clear-out" and will run fine at 4K cruise again. Any ideas on what this could be?

    Compression

    Considering the purchase of Twin '01225 Optimax's. Owner claims compression #'s to be 85-105 on one engine and 85-100 on the other. ~900hrs. Price is VERY reasonable....... Any opinions? Usable as is or not?

After replacing voltage regulator, burned wires going to the power pack and cleaning the optical timing sensor and underneath the timing wheel the engine started. Also wound up replacing the started......it was...

    Regulator Failure '95 175 Johnson

    Went out early this morning to go fishing.......while crossing the bay I noticed the Port Tach (twins) was behaving erratically, went to 0 back to normal and back to zero then the engine died.
