    96 Johnson 150 fuel delivery issues

    If you can see clear thru the fuel pickup tube, I am not sure what to suggest. Alternatively, sometimes the fuel pickup tubes unscrew from the elbow fitting, and there is a filter under the tube. Have you located the antisiphon valve? If not, that would be a good idea. They can clog.

    outboard motor mounting height?

    OK, if the A-V plate is 1.75" below the water when on plane, that is causing a lot of drag. Raise the motor 1.75" and see what happens.

    Johnson 150 V6 Ocean Runner - not starting

    Have you tested for spark? That motor likely has a shift assist switch that kills spark to 1/2 the motor. It also has overheat sensors that kill spark. If either malfunction, spark is compromised.

    96 Johnson 150 fuel delivery issues

    The Antisiphon valve is somewhere on the fuel pickup tube. Most screw into the elbow of the pickup. They look like aluminum or brass hose barbs, but have a spring and ball inside to effect the valve operation. Some A-S valves are located in the fuel pickup tube itself, as sometimes filters...

    96 Johnson 150 fuel delivery issues

    Check the fuel tank vent and the anti siphon valve in the fuel pickup tube. Some fuel tank pickup tubes have a filter that can clog. The A-S valves can clog. Fuel tank vents can clog as well. Were you using the water separator with the external tank? If not that needs to be checked for...

    Cleaning aluminum gas tank

    A hair dryer has a red hot element. Although sparks are unlikely, it is still a possibility, and real bad if gasoline fumes are still present. A lot of shop vacuums use motor brushes. These always spark, so don't use them either.

    The internet has a ton of supply places for nuts. Verify the thread size and see if you can find a thin brass one.

    Current Draw from Mercury Outboard Voltage Regulator

    A resistance of 1.6MOhms will allow .0000075 amps flow. Not very much current and 9 hundred thousands of a watt. Virtually nothing. Since you are seeing 1MA (which is still nothing), either your ammeter is not accurate, or you have some very small short somewhere.

    Cleaning aluminum gas tank

    After you remove the fule gauge sender, you will have a reasonable hole. You can use purple stuff cleaner, a swab, pressure washer, nuts/bolts/chains etc. What kind of debris are you trying to get rid of? Use some alcohol after you have all the water out to dry the tank.

    Boat hit 200 degrees engine temp

    Thermostats do not last forever. Did you change it? Ditto water pump impeller. The other thing is the rusting/clogging of the risers/manifolds. Saltwater means you are due to change them.

    Anti Siphon Valve on Fuel Tank Pickup?

    Dingbat, as long as your fuel line never dips below the top of the tank, even if it breaks, you will have no issue. Not sure your reference is complete However, most below deck tanks have a flexible fuel line that runs under the deck to the transom area, and then up to the engine or a filter...

    Mounting Nut for an Ignition Switch

    Is this ign switch for a MerControl? If so, that nut doesn't do much. The old ones were recessed with a lip, which I thought was really there to protect the key from being broken when hit with your arm or leg. I guess they held the Ign switch from being pushed it. You could take the new nut...

    Water line runs to backing plate drum brakes ?

    Some trailers had the ability to wash out the brake drums. Very useful in salt water. I would expect there to be a hose to both brake drums, unless it was "modified".

    2000 Johnson 150 Issues Running

    You do not need to pull the idle mixture screws out of the throttle bodies. They have a side cover over them. Pull the cover, spray 'em down with carb cleaner and install new cover gaskets. There are no other adjustment on the carbs, except for making sure the throttle plates open at the same...

    Water in foot

    Water can only get in via shift shaft seal, driveshaft seal and propshaft seal. First drop the gearcase and drain the gear oil. If you have a gearlube pump, take the hose and fitting and connect it to a bicycle pump and pump a couple of PSI into the gearcase. Use some soapy water on the shift...

    Won't go in park or reverse. Stuck in forward position

    You should have this moved to the MerCruiser forum. Those guys are experts. From my failing memory, when you install the drive, the shifter needs to fit into the yoke. The yoke needs to be parallel with the boats length. The outdrive has to be held in the correct gear to make that happen...

    2000 Johnson 150 Issues Running

    Sounds like the carbs are still dirty. Firstly clean the main strainer and make sure the oring and rubber gasket are good and inplace. An air leak into the gasoline line will cause more oil to be pumped into the gasoline, which is what you are seeing. The main jets are easy to clean. They...
