    Incorrect Spark Plug? - Evinrude Starflite 100hp 1972 - 100293R

    Hi All, I purchase an 1972 evinrude starflite 100hp (model 100293R) a couple of years ago and have been using NGK B9HS spark plugs in it as that was what was originally installed in it when I bought it. I checked the manual and it calls for a Champion L77V which apparently converts to an NGK...

    Trim tab hydraulic lines

I have attached some photos that show the connections on one my trim tabs. As you can see it is a plastic hose (it...

    1972 Evinrude 100hp Tilt motor wiring

    Hi All, I recently purchased the motor stated above and the tilt motor was broken. Assuming that all I had to do was buy a tilt motor and hook it up to power via a switch, I did not ask how it actually hooked up. I have since realised that there is either solenoids or relays associated with...
