    2016 Tohatsu 20 issues

    OK, model is critical; year is irrelevant. Is it an MFS20D? That's carbureted. The E series is EFI.

    No spark

    Nope. Verify no issues with the kill switch circuit. Also should not start in gear.

    Nissan 25 hp length short or long?

    Yes. Japanese motors are 2 or 3 inches longer than the old standard. It's a short.

    30 hp four stroke Tohatsu

    What is the model? Older models had carbs. If EFI, what is the fuel rail pressure? Is there spark signal from the ECU?

    Those props don't have replaceable hubs. Just install your spare prop.

    9.8 hp Tohatsu smokes on startup

    Yes. if the old 9.8B, it will smoke at initial fireup. If an MFS9.8A or B it might be overfilled with oil, or over choked.

    Nissan NS50D No Spark Issue

    That's the high speed esg (rev limiter) loop. It's a faulty CD.

    Tohatsu 9.8 one question

    The 9.8 does not have an oil filter. I like to change around 10 or 20 hours initially, then every 50 thereafter. Same for the LU lube.

    New to me 2020 Tohatsu 9.8 unable to go past 70% throttle, won't restart hot.

    Yeah, there's a lot of trash in the carb. set the rubber bits aside and ultrasound overnight. flush the fuel pump too. After the soak, I usually blow out all passages with generic carb spray.

    2012 Tohatsu 30hp 2-stroke jet bogging at WOT

    As I mentioned on that other forum, a leaky o-ring in the fuel line could cause that.

    2004 Tohatsu 90hp tldi error code 7000 and the battery light

    So it ran fine until you changed plugs? What the heck is a top float bolt? Gauges go on the schraeder valves on the fuel and air rails.

    The 3M3 is also used with the bigger carb to get 18 hp.

    honeymoon over...MFS6D

    How did they adjust the pilot screw when it has an EPA plug blocking access? It's a violation of federal law to take that out. If you can't idle down low enough, that really sounds like some varnishing in the low speed circuit. Do you run the carb dry at the end of each day, unless you are...

    Unreliable spark Tohatsu MFS6C

    The issue with intermittent electrical items is that you can't measure the failure unless they are failing at that moment. I have never seen a failed ignitor, but anything is possible. Make sure the insulation of the brown kill wire is not damaged.

    Tohatsu 9.9D2 after wrong modification?

    Apparently. Many upgrade the old 9.9s to 15s by installing that cam.
