I've removed a lower unit , by using a drill&hole saw to bore a hole in the tower ;then used a reciprocating saw in the hole to cut the drive shaft , then later pull the drive shaft and re-weld the drive shaft back together. That was on a 20 horse merc. Then replaced
the piece that was cut out ,using Marine Tex.
You want a Yamaha 50 3 cyl

Go to smack boat section, Yamaha 50 triple with moded intake/head & low water p/u will
easily get you in the 50's++ with bolt-ons!
Let me know how it goes?
