    Crank seal issue?

    spark timing at idle is about 7 I guess, but you need to see if it advances to maybe 25 if that is what your service manual calls for just disconnected the pointer on the cdi at linkage and moved it by hand while motor was idling to see both were in spec, on my 1999 C40 I guess your 70 is like...

    Crank seal issue?

    I would make sure the spark timing is in spec and that it advances in spec also, by using a timing light. If a cylinder is not burning the fuel properly there will be some fuel/oil mix going out thru the exhaust. very hard to make sure spark is happening on all plugs when there is loss of power...

    I wonder if being tilted up allowed the oil pump pick up to suck air. also does anyone know if the oil pressure sensor is a switch or maybe something that sends a variable signal telling how high the pressure is. could be mapped to RPM and pressure being within a certain range this motor has...

    2004 Yamaha 150hp oil sensor light

    I hope it was a wiring connection problem or bad sensor and not really low oil pressure. that would be bad on the power head

    89 Yamaha 70hp two stroke opinion

    I would think you need to find out what the problem is. something it leaking. my guess is check valves on the oil system as far as running the fuel out of a multiple Cylinder motor with multiple carbs means that some cylinders will be running lean or without oil and fuel because the lower...

    Yamaha F70LA Tilt Not Working

    my guess is the contacts inside the relay are burnt and not making good contact, but it could the brushes or other things in the T&T motor/pump binding up.

    Yamaha F70LA Tilt Not Working

    since the relay is clicking it seems the controls work ,I was talking about jumping the main power wires to the T&T motor But you do need to disconnect those wires from the T&T relay since in the none energized state they go to ground. this is for My 1999 40, but I quess it would the close to yours

    2018 Yamaha 115hp Spark Issue

    I have no idea, since I never owned a 4 stroke Yam but I would think it would not be the same as a suzuki as far as specs but I could be wrong. kills switch should take out all spark not just some there should be stuff to charge up things and others to tell it when to fire the plugs

    2018 Yamaha 115hp Spark Issue

    how did you check spark? Are you not getting spart to any of the plugs or just some of the plugs? you need to monitor the inputs to the CDI and the out puts to find out what is going on. I do not have a manual for your motor, do you so you can look at the specs

    OEM Yamaha aerosol paint code for 2000 0x66
