    Rough running Evinrude V90

    Try this tester (open air adjustable -- and cheap at an auto parts store). Start at about a half inch or a bit more, and dial back if the spark intensity is uneven:

    Spark plugs for my 1973 65 hp Triumph

    I never contradict a man who wrestles alligators, but might add a suggestion. I would get an open air adjustable spark tester and test the ignition system before deciding on plug gap. I believe your motor would produce a 5/16 (?) spark if in good shape, although maybe less. If the ignition is...

    Top cylinder not firing Johnson 55ESL69A

    Remove the plugs, and test each lead with one of these:

    My 1977 Johnson 70 Horse Struggles All Combined

    Soak, thoroughly clean and rebuild carbs. Insure there is no water in the fuel (glass jar -- water will show up at the bottom). Resurface mating surface of the head. Assume it is warped.

    Johnson 25hp Rpm's

    ^^Agree. Combination of adjusting idle air screw and throttle idle. Make sure red valve on primer is set parallel to the solenoid body for running.

    1967 evinrude 80 hp need help.

    Rig looks to be well-kept and original -- right down to the air guide gauges and original controls. Think you need to preserve it.

    Idle surge

    Make sure all fuel hose connections are tight. Air leak can cause surging. If running dual tanks simultaneously, you presumably have a directional valve at the transom. That hookup may be the a source for air leaks.

    9.9 Evidrude stalls when fully excellerated

    Test compression and spark first. Look for compression in the range of 110-120 psi, and spark around 1/2". Can probably rent a compression tester from an auto parts store, and buy a $10 spark tester there too (open air adjustable -- not the inline type.) First carb might be a little...

    1987 johnson 70vro 8 years since start

    Fresh impeller, but I would clean and regap old plugs initially -- no sense in fouling new plugs while bringing it back. Use fresh mix. If permanent tank, switch to portable until it's up and running (50:1 mix), plugging the auto oiler. In the meantime, dispose of the fuel in the permanent tank.

    Rough running Evinrude V90

    no. Don't get into the reed valves yet. Test cylinder compression with a standard tester (reed valves have nothing do do with cylinder compression values.)

    Boat won’t start, I’m at a loss

    Key in run position when jumping?

    Rough running Evinrude V90

    Test run it with a portable tank and a 50:1 ratio. Testing on muffs has limited utility, as there is no back pressure. Further, water pressure from the hose substitutes for action of the water pump, so not a good test of cooling system.

    1980 35hp Johnson --Wont Pee

    Agree with above. But check the top of the head to see if it's overheating (i.e. too hot to touch for a few seconds). An IR tester is a very good investment.

    1994 Johnson ocean runner spark plugs.

    (I trust everything Vic S says on plug selection.)

    Put it in the lake or a test barrel (with water about half way up the leg.

    Big twin 40hp shear pin material?

    Och ja, as my Dad would have said. He would not have been a big fan of hole shots -- not much for WOT either, although he let me do it.

    Big twin 40hp shear pin material?

    I like brass shear pins for fishing -- trolling with smaller motors through weed beds and some shallows. I use stainless drive pins for larger motors -- never been sure that the torque of a 40hp wouldn't be enough to shear a brass pin, but not really aware of a case where that happened.
