    18 HP Tohatsu 2004 18B Link rod removal on carburetor

    On the MFS15/18B2 carbs, it takes time and patience to disassemble the pump rod and boot, but I have done it. No special tools or force needed.

    tohatsu 9.9HPEFI converted to 20HP issue/question

    There is indeed a different part number that gets used when the restrictor is removed. 3RS024180M GASKET (MFS20) $5.63 Probably a bit longer to make up for the missing restrictor. I believe the real issue is that you now have double the power, so need some more pitch.

    2006 Nissan 9.8 NFS9.8A3 Revival

    If you have compressed air, blow that in the pee tube while the motor is idling. That will help dislodge a bunch of crud.

    07 Tohatsu 3.5 4stroke...overheating?

    Anything around 150F is fine. When was the last time the wp kit was done? If run in salt and not flushed regularly could have buildum in the head areas.

    What's wrong with my new 6hp Tohatsu?

    Not familiar with that model. if air from intake, there is some valve leak... if crankcase, likely rings. Re seafoam; it's just mineral spirits, so your mileage may vary. I prefer real carb dip in gallon cans from the auto parts house.

    NSF18b2 oil light issues

    Pee hole only dripping water --- 15hp Tohatsu

    Rule out (or in) overheating. Use a gun type IR thermometer. Cheap at HF and other places. Engine should not be going over about 150F. Stat has NO effect on the pee tube. I trust you did an OEM WP kit, not some cheapie impeller that may fit incorrectly. What is your actual model (not year?)

    What's wrong with my new 6hp Tohatsu?

    If compression comes up a lot with some oil, yes, rings are leaky. Compression testers are notoriously way off, so don't trust that number. Tohatsu America denied the warranty in under 5 years? That sounds wrong. I've seen them be very generous with warranty. The seriaql number will allow them...

    NSF18b2 oil light issues

    The "plunger" is the pressure relief. Should hold about 40 or so PSI. It could be stuck partially open. I have seen that. 3V2076200M PLUNGER $26.35
