    1989 Force 5hp - The lever handle sits level for neutral, and down for forward. It does not look like it has reverse, am I right? Never had a small hp motor, never saw an outboard without reverse, is this normal?

    I have a 1989 Force 5hp Mercury Model H0052F89A. I'm trying to remove the flywheel, since I'm getting no spark. Is the flywheel bolt a left handed thread? I'm treating it like a regular right hand thread and it is not budging.

    Engine Cover Disconnects Cables

    The engine cover on my newly acquired 1990 Johnson 115 Crossflow Bubbleback V4 has to be put on very carefully from the rear or else it'll disconnect the spark plug and coil wires.
