Back in my younger & stupider days I built a screaming hot Evinrude 235 and sold it to a dude that wanted it installed on a 17' Ranger. After installing it I took the rig and 4 different props out for some runs to PROP IT OUT and to set the jackplate.
Once I felt that I had it set up, as good as I could get it, I cracked her wide open and just let her wind up real good.....Holy Mother Of God ! 😬
When I set that boat back down it bow-hooked, I over compensated, and ejected myself over the port side into 48° water. When I climbed back into the boat I hooked the kill switch back up and tried to restart it.....Nope. Dead. The battery had come loose and ripped the terminal off the cable. I half-assed that back together, started the motor, and idled SLOWLY back to the trailer..... which luckily I had left in the water, because nobody else was at the ramp that day.
Didn't realize how cold I was until halfway back home. Got undressed in the shower under warm water. Busted a rib (bruised from my belly button to my left nipple), and lost my glasses, but bygod I was ALIVE !
Never again!
