My brother used one all last year (May-October) pushing a Pelican
International Intruder 12' jonboat. Probably has 100 hours on it so far.
Not a problem. Doesn't sound like your typical 1 cyl. outboard... much
lower revs.
I have a 3 year old 5 hp Tohatsu 4 stroke motor. It has about 200 hours
on it. Cost a little more than the B&S. Burns less fuel. Accelerates
slightly better. A couple pounds lighter. About 30% louder. Not a bad
motor for the money. Better than the B&S, but that should be expected.

I might want to get one of these on my
next small boat for river and small lake
use. I like the idea of not having to
change the impeller(not fun) or mix gas
and oil like my old mercury.
I like the idea that any Briggs dealer
will service it and would have parts way
cheaper than the marine dealers.
I wish that the Mantis Tiller company would make an outboard attachment for
their mini tiller. Those things start so
easy, weigh nothing, have good power
and already are set up to interchange other
attachments like a hedge trimmer bar.
Fish with it in the morning, till with it
in the afternoon...
