Montgomery 23 Motor Question Answered
I asked the question a few months ago about what motors folks had on their Monty 23's. I got a lot of answers, most of which led me away form the 6 HP motors. After carefully researching, I found a surprising thing. The motor that I thought was best was also the cheapest. I ended up getting a Nissan 9.8HP 4 stroke. In CA 2 strokes are no longer being sold. I chose this motor because it is the lightest in the class. Most of the other's (Nissan 9.9HP included) are detuned 15 HP and weigh a lot more or they just weigh more. The motor is very quiet. At an idle you can hardly hear it running. The motor is still in its break-in period, but at 1/4 throttle it pushes the hull along nicely. I doubt I will use it much above 1/2 throttle unless fighting a strong current and wind. I would have run it longer, but the wind picked up to 12 knots. Let's face it, I'd rather be sailing. With a reefed main and small club jib, we were heeling at about 30 degrees with big smiles on our faces. The break-in will have to wait until the next time. _____ 73 de AC6KW <mailto:jeff@grudin.net> Jeff Grudin, DVM Web Add: http://www.grudin.net Ocean Animal Clinic / Cat Clinic of Santa Cruz - Santa Cruz, California Montgomery 23 Hull #072 Norcal QRP * QRP-L * ARS * AR Qrp --- Outgoing mail is certified Virus Free.

Jeff: I think the Nissan/Tahatsu 4 HP will be my next motor if I ever give up on the old Johnson SailMaster. They appear to be very good motors. It would be interesting to see the difference between your 9.9 and a smaller motor, say a 4 or 5 HP, both from motoring performance, as well as sailing performance with less weight on the transom. At 12 knots wind you were heeled 30 degrees with a reefed main and small jib? What are you going to fly when it's blowing 30? At 12 knots of wind, I'd be doing 5 to 5.2 knots boat speed flying the full main and a 150% and maybe heeled 10 to 15 degrees and hoping for a bit more breeze. Somewhere in there, the rudder and boat in general start to hum and quiver as the boat starts to plane and the speed jumps up to nearly 6 knots. Too much fun!! But at 30 knots, that all changes. By that point I'm down to a double reefed main and storm jib, and still heeled 20 degrees or more. Things move fast and with force. It's still fun....but in these conditions, one better pay attention to what's going on or the pucker factor may get tested!

Sadhana, my M23 would heel about 15deg at 12knt true with full main and 110 jib. You must not have the draft far enough forward and are getting more drag and less drive. Dick Howard Audsley wrote:
