    5hp hard start

    Model is likely M5B. Verify the fuel pump on the side of the carb. Use the carb drain to verify whether the carb is full when trying to start. If it smokes a lot, might be flooded. Do you choke it when warm?

    9.8 Tohatsu dies out after initial start

    The jets are not adjustable. I would check that you are getting good fuel delivery. A leaky o-ring in the fuel line could cause that symptom.

    Can you change a Tohatsu 9.9 hp to 20 hp?

    Exact model is critical to knowing how to upgrade. Year is irrelevant.

    Can you change a Tohatsu 9.9 hp to 20 hp?

    The 9.9/15/20 E are all identical blocks. I assume that is your model. EFI difference is in the air restrictor and ECU. You need to change both. Price about $1K. Better to sell and then buy the model you want.

    Motor swap limp mode

    Full wiring details are in the Factory service manual. If there are no warning lamps, the motort thinks the motor is not pumping water. If the lower oil level lamp is ON, there is low oil in the reservoir. See p. 61 of the owner's manual at Tohatsu.com.

    2010 25 toh 4-stroke head gasket help

    Seafoam is basically mineral spirits. Never had any luck with it. Your mileage may vary. Possible the rings aren't fully seated if it's never been run really hard and hot. I have checked valves on tons of these, but never found one that needed adjustment. A decarbonizing spray session won't hurt.

    2010 25 toh 4-stroke head gasket help

    The 25B is EFI... good motor, same as the 30 except for the ECU. I would do a leak down test, looking especially on that low compression middle cylinder. Also make 100% sure the oil is not over full.

    Tohatsu 4hp fuel selector switch stuck

    The 4/5/6 are identical except for the carbs. Easy swap. The fuel valve is fairly cheap. YMMV.
