    1992 - 2002 Tohatsu/Nissan 25 Cylinder Boring Question

    Lukus, Can ask whatever question you need to know, nobody was born with boating skills, it's a learning curve. Exhaust chamber creates excessive heat buid-up, needs to be properly water cooled. This pic corresponds to my 2 cylinder OB, although cylinder head and front crankcase water...

    Tohatsu m18c need carb kit and fuel pump kit.

    Personally before investing on a carb & fuel pump kit, would invest on a cylinder head gasket along a thermostat if in bad shape. Gaskets don't last that long if cylinder head has not been re torqued sometime after break in period ended and from time to time. Gasket cedes, compresses, and...

    With OB constantly use, will see white lines forming on cylinder head gasket and water droplets leaking in middle gasket metal ring. OB will miss/hesitate when on cold starts. Warming OB more won?t cure the symptom, will just remedy it shortly to miss again when cold. This head breaking symptom...

    Deezy, Trim OB to 90?, this is the ideal leg height when middle water flow passes (yellow line) at fast displacement speed. Check if flow passe above yellow line, how much under towards larger lower anticav plate, report findings.. Height must be dialed spot on before passing to a prop...
