    Reed/Leaf Valves

    That would be correct, this motor does not have the quick disconnect.

    Reed/Leaf Valves

    I do trailer the boat with motor tilted up slightly and fuel in the bowls. I haven't tried the squeezing of the bulb and checking for leaks yet.

    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

    Pulse limiter looks clean inside, vapor pump looks good externally but may have to disassemble to inspect it internally.

    Temperature switch circuit 2000 Johnson 150hp

    I performed the fuel pump test per the Johnson service manual 3 times, results say air motor diaphragm and/or vacuum rectifier leaking- replace air motor diaphragm. Would this be just a rebuild kit for the fuel pump? Also the two wire temp sensor seems to bad, "hot" light displays when key is...

    Temperature switch circuit 2000 Johnson 150hp

    Since the two wire sensor is no longer available, to replace it with a one wire sensor do I tie the 2 wires coming from the harness together and connect to 1 wire coming from sensor?

    Temperature switch circuit 2000 Johnson 150hp

    I am sure it is a worn impeller as the stream from pee hole is weak at low rpm.

    Temperature switch circuit 2000 Johnson 150hp

    I checked fuel pressure on this engine a couple years ago and it had about 5psi. If my compression readings are indeed low at 92-94psi would this not be enough to pulse the fuel pump causing it not to pump fuel? In addition to checking the fuel pressure I also removed drain plug on 2 carbs and...

    Temperature switch circuit 2000 Johnson 150hp

    It shows hot on the system check gauge, I can unplug the two wire sensor and goes away. Something definitely happened to the fuel system when it overheated, I can manually choke it pump primer bulb until I get fuel into the manifolds and it starts fine but I have no fuel pressure ( verified by a...

    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...

    1992 115hp Johnson Lower Unit Froze Up?

    I am working on a 1992 Johnson 115 for a friend, the engine has not been ran in about 2 1/2 years.I cleaned the carbs and got it started and idling good but when I tried putting it into gear I could not get the shifter to move out of neutral. I disconnected the shifter cable and tried to...

    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...
