    1975 135 HP Timing Issue

    I followed the posted 'substitute' WOT timing protocols and found that my current setting was around 18-19 (+ the 4 factor = 22-23). I wanted to retard the timing to 16 (equals 20 as per manual) but I ran out of adjustment possibilities (only about two turns left) and could not change the timing...

    Proper Plugs for 1975 135HP

    I have seen quit a bit of posts regarding which plugs to use as replacements in the older engines. There's enough variances in these to prompt me to ask this question. It seems pretty common to agree that the UL77V (or equiv) is not really optimum unless high-speed use is the norm. But with...

    Johnson Warm-up Lever Problems

    1975 135HP Johnson Following the manual my warm-up lever should be able to rotate the throttle cam to the START position. But it doesn't. Barely makes it half way even with the limit screw on the controller all the way out. Assuming everything else is okay, with the linkage and cable is there...

    1975 135HP Johnson Carb Linkage

    I've finally received my Johnson Service Manual and have read through it. I was getting ready to perform some of the basic carb linkage adjustments when I noticed a discrepancy. The manual shows a solid link between the two throttles, while the choke link is two parts with an adjustment...

    Help with Timing Light

    It's been about twenty-five years since I used a timing light. Now I find myself needing to use one on my outboard. I acquired a timing light a few years back when I inherited this old boat and now need to put it to use. It is an old Snap-On MT-215. The power cable has two aligator clips are...

    1975 135HP Johnson Fuel Line

    I noticed a crack in the fuel line between the engine cowling and the fuel pump. It did not go all the way through as best as I could tell by pressurizing with the primer. I cut off the cracked area (near the pump) and reconnected the line to the fuel pump, but it is now too short and runs the...

    135ESL75E won't run past 1/2 throttle

    Okay so this wasn't an 85HP. Now that that is settled, I have another question. Earlier I went through the ignition system, (back when we thought this was an 85) and the voltages and resistances were okay. I replaced the coils, since I had two cracked and one bleeding. The boat still...

    How do I assemble new ignition coils

    I just received my new coils (Sierra 18-5194). I've never assembled plug wires before. How does the conductor, boot, and spring go together?

    Is this a 135HP or 85HP Johnson???

    To date I have been assuming my motor was a Johnson 85HP due to the model and serial number on the stern bracket. But now I have uncovered the welch plug and find different model and serial numbers. Welch Plug: Model number is 135ESL75E Serial number J4333712 Stern Bracket: 85ESL-73M J3894160...

    Prop Strike 1973 Johnson 85HP

    I read that, "Any impact caused by hitting an underwater object is absorbed by the propeller hub" Which I assume means no sheer pin on my motor. So I am not sure exactly what will happen if I hit an underwater object with the prop. I've never taken the prop off myself so I've never looked...

    Fuel Line Hardening

    I have gone through several fuel lines in as many years. After sitting over the winter I find the lines become extremely stiff. The first two were Atwoods brand and the third was a brand from Bass Pro (I don't recall the Mfg. but they only carry one brand). All three were the grey colored...

    1973 Johnson 85HP Cylinder Order

    I need to confirm which cylinder is which on my 1973 Johnson 85HP (model 85ESL-73M). It has used head covers, put on due to stripped out spark-plug holes. These were off a different engine so the numbers are not correct on the covers. I found small numbers stamped on the heads as follows. Top...
