I run an old honda 9.9 four stroke. It is great. Reliable, quiet, and cheap. I picked up mine used for about $400.00 USD. I have put about 150 hours on it and I love it. Starts with one pull. I did have some problems with corrosion on the kill switch and have disconected it. If you are like me and not made of money, do yourself a favour and spend a day looking at used 4 strokes.

I run a 22' glasply at about 3500 lbs. Top speed is about 5 knots.
