Re: Anyone know what a 1996 Yamaha 20hp 2 stroke short shaft motor weighs?
My 1998 book says 105lbs for the 25HP and 79lbs. for the 15HP, no mention of a 20HP. Just my guess, but I'll bet your 20HP is either a tuned up 15HP, or a tuned down 25HP. This don't answer your question, but 79lbs. or 105lbs. could be pretty bad on your back, if you're gonna be loading it on and off your transom very often, especially by yourself. I had a 4HP that was about 50lbs. and it was a grunt to put on the back of my canoe...at least for this old geezer!
