    Reed/Leaf Valves

    Can faulty reed/leaf valves cause the fuel/oil mixture to seep out of the carbs? Could an overheated engine have caused damage to the valves? After a day on the water I have traces of the fuel/oil mixture seeping down from the lower engine cowl cover onto the mid section. I have checked hoses...

    2000 Johnson 150 hp Port side temp switch

    This may have been answered in my previous post but I was unclear on procedure. My port side temp switch (2 wire) is bad and it is no longer available for purchase. Can it be replaced with a one wire switch and if so what is the procedure? Thanks in advance.

    Temperature switch circuit 2000 Johnson 150hp

    When the temperature switch is activated and shows that the engine is hot is this just a visual warning or does it cause the engine to go in "safe mode" of operation and reduce fuel or spark? My engine overheated and I had no choice but to continue to run it until I got to an area where I could...

    High Speed Orifice Jet Size

    When an engine has been bored oversized (.020) should you increase the high speed orifice jet size? By model number my engine calls for #59D jets with other models listing #69D and #70D. Should I stick to what is recommended for my model engine?

    2000 Johnson 150 - Only 1800 RPM Under Load

    Per the OMC manual I performed a stator resistance test. Used a digital read out Fluke meter on the audible continuity/ohm setting and got a reading of 0.4, manual states for V6 35 amp stator reading should 0.12 +- 0.07. I also checked (per the manual) for a grounded condition but got no reading...

    2000 Johnson 150 Timing Pointer Check

    I am attempting a link and sync on a 2000 Johnson 150 Ocean Pro with the OIS ignition system. I bought the OEM manual P/N 787070 inside the cover it shows what models it covers, I do not see my model listed (J150vxsss). Would this still be the correct manual for my model motor? Anyway the first...

    2000 Johnson 150 OIS Spark Issues- New Problem

    In my previous topic you very knowledgeable people pointed me in right direction in diagnosing a bad shift switch cutting spark to half of the motor. As I stated in my previous post I bought this as rebuilt unit with only carb tuning run time on the motor. The motor must have been tuned to a bad...

    2000 Johnson OIS Spark Issues

    Need some direction on what would cause little to no spark on one whole side of the motor. Facing the motor from the front the right bank has little to no spark and as a result the motor stays in the high idle mode for about 5 minutes because that side is not heating up as much as the left side...

    1998 Johnson 150 Ocean Runner will not idle when engine warms up.

    Need some guidance / opinions on what is causing this engine not to idle when it has warmed up. It will stay running when cold started and after making a run at near full throttle it will come back down to an idle and stay running. After I turn it off and let it sit for a few minutes I can crank...
