My opinion on the right motor
Charles: I have a Johnson 6 HP which is a 2 stroke, so I must mix oil with the gas. Last summer it needed some work after 22 years of use, and I was away on business, so it went into the shop for a few weeks. Someone let me use their spare Honda 5 HP motor. I always thought that I would replace my motor with one of these if I ever had to, but after using it for a few weeks, I can tell you that that is not the right motor for a C-22. My boat went about 1 knot slower with this motor, which if you ever have to motor 25 to 30 miles, makes a big difference. It was a 1 cylinder motor, and did vibrate, and was very heavy. It was quiet and very fuel efficient, but it had a very nasty habit of sometimes pulling back on the starter rope so hard that it could hurt you. This happened to me twice, and my son once.I recommend that you try to find someone who has the motor that Tom D mentioned in the previous reply and ask them to let you check it out thouroughly. I think that Taohatsu makes the same motor. If you could get it without the stickers on it, all the better in my opinion. I do think that a 6 HP, 4 stroke, 2 cylinder motor would be the right motor, unless you have great currents to deal with where you will be using your boat, then possibly an 8 HP, but this would add weight. Anyhow, make your decision carefully, I was happy to put my old motor back onto my boat. At the shop where they repaired it, they said that they could keep it running forever. I would still like to replace it in a few more years. I still don't like mixing oil with the gas. I think most of it ends up in the water, and I could carry much less gas if I had a 4 stroke motor.
