Mounting the outboard motor
This video is a good video tutorial on how to safely hoist your outboard motor onto your transom, boat it on and install your steering cable. It’s dangerous to put a strap on your motor and hoist from below but it can be done. The 3 fly wheel connections is how Johnson, Evinrude, OMC want it lifted. Other brands have loops built in to the block. A rented engine hoist will make this job go even easier.
Wiring it back on is a different story and will depend greatly on the make of you motor. Take pictures before you take it apart if you can. If you can’t, search the web for wiring diagram for your specific outboard manufacturer.
