    Power trim stalling motor (hpdi )

    he said they both raise and lower the motor ,but the one on the control causes the running outboard motor to mess up. Not the T&T motor

    Power trim stalling motor (hpdi )

    that does not make sense to me. Does the T&T work from both switches? You might try to measure the battery voltage while hitting each of the switches to see if there is a difference

    Power trim stalling motor (hpdi )

    Sounds like the T&T is pulling the voltage down. clean all battery cable connections and make sure your battery is load tested and good

    1992 yamaha 2-Stroke 85hp tiller handle lower unit

    someone trying to shift while motor is not running can cause the shift shaft to twist. found that on my brothers old C60, along with the bent pin. But maybe someone did not have everything in neutral when stabbing the lower unit in

    2020 DF35A 30hp conversion.

    title says change from a 35 to a 30. to change HP I would think you would need to change amount of fuel and air. and maybe timing advance at WOT Some may just change upper rpm limits I know nothing about the Suzuki's

    99 3.1l ox66 wont rev (what am i not thinking of here)

    hard to believe one cylinder would cause that much difference, but who knows for sure. I am not sure what a non-functioning Knock sensor would cause. but I would think the ecu would probably adjust (Back off) timing to stop a knock

    99 3.1l ox66 wont rev (what am i not thinking of here)

    Yep, think it was the Z motors that dropped cylinders at idle and dropped more if you revved it while in neutral

    99 3.1l ox66 wont rev (what am i not thinking of here)

    some motors limit RPM while in neutral, but have no idea if yours is one of them. I am not sure how the ecu limits the RPM, dropping injector firing or spark on some cylinders maybe. need to make sure the ECU sees it is not in neutral when in forwad gear timing light should show if spark it...

    reverse does not load it up as much as forward is my only thought on that. and a lot can happen in 2 years on the injectors

    have you monitored spark timing to make sure it is advancing properly?

    Yamaha F225 ECU Upgrade

    cool, let us know what you come up with. Alarm going off and not limiting RPM to around 2K makes no sense to me. I guess that is what that motor is suppose to drop it to

    Yamaha F225 ECU Upgrade

    do you know how the oil pressure and temperature is measured by the ecu? Are the sensors variable resisters that send back a variable voltage that the ecu converts to pressure and temp? seems the old school thing was just switches that connected to ground when they were out of spec. now a days...

    Yamaha F225 ECU Upgrade

    very strange it did not go into RPM reduction when the alarm was sounding if it was for low oil pressure or over temperature. not sure how that can happen if the ECU is the one that sees and responds to the sensors saying they saw a problem. could it be that the ECU just lost contact with the...

    1989 70hp Yamaha cooling system flush

    Pull the thermostat and leave the housing off so you can see what all come out when you (while you have the lower off ),hook a hose to the pipe heading up to the powerhead turn on the water and hope you get most of the pieces out of the cooling passages. On a motor that old you may end up...

    that is correct but the meter will indicate what the problem is so you don't have to guess
