    40 hp johnson electric shift Model # 40ES 69R

    The proper Oil is marketed by BRP as Precision Blend. It used to be called Type C. Be aware though, that there are some 3rd Party Oils claiming to be Type C, but are not Compatible with Electric Shift . The proper oil is less Viscous than 75-90 gear, being that there will be some residual Oil...

    Deadman Switch?

    If you use a Safety Chain/Cable on an Outboard, it has to short enough that the Motor can not get more than 1/4" higher than when it is clamped to the Transom. The last thing you want is an Outboard, at WOT jumping around back there, tied to the Boat. You also have to rig it so the Motor can't...

    1979 Glastron T166 XL Sportster Bilge Holes?

    Water is/has gotten in there, be happy it has a way of getting out. You are going to have check the Hull, and anywhere where water could be splashing up along where the Hull and the Cap are joined. A 44 yr old Boat is liable to have a few leaks

    High compression in 1 cylinder - 7.4 carb

    Marine, RV/Truck are not the same Cams. Most trucks just use the regular Auto Engine so no "Truck Cam". RV cams, are still different than a Marine Grind. "Close" is really only Valid, with Horseshoes, Grenades, and Nuclear Weapons. If you need a Cam, get one from Mercrusier, a few extra bucks...

    over fueling at idle

    If the Injector isn't closing completely, it will drip. A can of Miracle Elixir might remove any deposits on the Pintle, but replacement is usually the fix.

    over fueling at idle

    I suspect that once the engine has warmed up, that ice melts and proper Airflow resumes

    over fueling at idle

    Okay the Injectors are higher up than I realized. That "looks like Frost" is exactly that, Ice. Humidity Levels must near 100% at the time

    Everything done but low rpm at WOT. Distributor spring?

    Means no Restriction in the Airflow, which means the Carb is not too small.

    over fueling at idle

    If it was a Carb, it would be easy to diagnose, EFI on the other hand, is the worst of Voodoo and Black Magic. If the engine is a 98, I doubt it would have O2 sensors, so it doesn't run a in a Closed Loop, but just uses basic things like Ambient and Engine Temps to adjust the AF ratio. Being...

    1986 90hp johnson primer bulb collapsing..hear me out

    If the`Primer Bulb is collapsing, then there an Restriction, in the Fuel Line, Fuel Pickup, Pickup Strainer, or in the Tank's Ventilation. Loosening of the Filler Cap, can verify/rule out Tank Ventilation.
