    Timing question 1986 70 hp

    I have a nice 1986 evinrude 70 hp I picked up. Going over everything the timing plate doesn't seem like it has a lot of range from idle to full throttle. It is contacting the rubber stop at full throttle but when I move the throttle back to idle the timing plate only travels maybe 1 to 2 inches...

    Nissan 25 hp length short or long?

    I bought a 1988 Nissan 25 hp ns 25 c2. Not sure if it's a short or longshaft? Measures 18 inches from where it rests on transom down to cavitation plate. Seems too long for a short shaft but too short for a longshaft? Thanks

    Disable oil level sensor 2001 yamaha 50 hp

    Looks like to me that the oil sensor connector remains unplugged? Just the pink wire is used. The other wires in that connector are for a Guage if being used. As for the trim sender, the connector also remains unplugged. To plug into those connectors you use 2 harnesses that would lead to the...

    Disable oil level sensor 2001 yamaha 50 hp

    Maybe it's just coincidence that the oil sensor plug fits into the trim sender plug? Maybe missing the wired that would have the connector for the oil sensor to plug into? Makes no sense to me either why the oil sensor plug would plug into the trim sender

    Disable oil level sensor 2001 yamaha 50 hp

    Finger points to the Grey (may have been white when new) wire that runs to the connector that goes to trim sender. There is a pink wire from the low oil sensor that may have gone to an unplugged pink wire I found.

    Disable oil level sensor 2001 yamaha 50 hp

    So the 1st pic is near the main harness connector. There is a Grey (might have been white when new now faded) wire that comes out of the bundle in 1st pic and runs to connector in 2nd and 3rd pic. The connector in 2nd and 3rd pic has red and black wires leading directly to trim position sender...

    Disable oil level sensor 2001 yamaha 50 hp

    So unplug the whole connector? Looks like the power trim position sender is plugged into the oil level sensor? Seems strange. I don't need the trim sender to work.

    Disable oil level sensor 2001 yamaha 50 hp

    I am removing oil injection system from 2001 50 hp 3 cylinder 2 stroke. Will not having the oil level sensor plugged in cause the engine to go into limp mode or cause a warning horn to sound? Finding mixed answers to this. Thanks
