If you look on the top of the crankshaft (the part in the middle that’s pointing up) you can see that there are two small flywheel keys on the left. I needed to take out these keys in order to finish taking apart the rest of the motor, but I couldn’t figure out how! They seemed to be locked in place and wouldn’t budge no matter what I tried. WD-40 and 3-in-one oil didn’t work and I even went so far as to give them a knock with a hammer and chisel (this last option wasn’t such a great idea, as you will risked damaging the keys). I finally solved this problem by getting some help from an experienced engine ‘wizard’ who was a leader for the Saanich Small Engines at one time. He simply pulled some pliers out of his pocket and – hey presto! – the flywheel keys were out.
And that’s how to get your flywheel keys out of an old outboard motor. Just be sure you don’t squeeze to hard on the key or you could risk damaging them. Be sure that they are in a safe place where they won’t go missing. With some old motors you can never be sure where that replacement part will be found.
Pliers are useful for removing flywheel keys.
