Whats the biggest boat that a 6hp Johnson will work with.

I used to have a 6-horse Yamaha stick-steer on my 12ft. jon boat, but since I got a 14 footer a couple years ago I decided to sell it and just get a powerful trolling motor.

How about a 15' fiberglass?  I already have the trolling motor.

I;VE GOT A 14' LOWES THAT HAS A 6 H.P. ON IT BUT IT ONLY WEIGHS 240 LBS.  I HAVE WISHED I HAD GOTTEN A LARGER MOTOR FOR IT.  I DON'T THINK I WOULD PUT IT ON A FIBERLASS BOAT.

The motor will "work" on about anything; the question is, what are looking to do with it? It isn't going very fast no matter what you put it on. If you're a big guy, it's going even slower. If you're not overly large, I'd think it would do OK on a 15' fiberglass, my buddy has a 9.9 on a 12' fiberglass Sears Gamefisher jon-style boat. Just don't try to take it the length of Sam Rayburn or across Champlain, and you'll do OK.

I'd probably find an inexpensive 14ft aluminum. You might be suprised how well it pushes one of those around. When I was a teenager I had one of these with a little Mercury 4.5 horse and while it was no speed demon it got around pretty well.

A lot of the boat rental places have 6hp Johnson or Evinrudes on 16' V's. I have a 8hp that I have put on my 16' Jon and it does all right, just don't be in a big hurry.
