Hi Craig, A few more thoughts from my point of view. On an M15 you aren't going to run the motor at much more than half throttle to achieve hull speed. Any more, and you just dig a big hole in the water and make waves. The waves show you how much horse power you are adding to the water. Fewer waves are better.......... All motors have a little vibration. Single cylinder a tiny bit more than two cylinder engines. It's only when you get to a 6 cylinder car engine that you find engineering harmony and a totally balanced engine. Manufacturers do a good job of balancing engines. My single cylinder Honda is delightful: no nits to pick. I have a Fulton lift mount - installed last year - and have no problem with the engine and vibration whatsoever. If you are only using your engine on the M15, there is no need for a break-in period. That idea is to keep you from taking it out of the box: putting it on the stern of the boat; filling the boat with 6 people; and then trying to pull a water skier.................. i.e., full bore operation without a break-in period. Since you are only using it to move your M15, and half throttle is about full hull speed for the M15, you are well below recommended break-in RPMs for the engine. So, just hang it on the stern, and if you have no snow, go out and play......... Connie
I agree with Connie. I hung my brand new Honda 2hp on Poco's motor mount and, on a windless day, cruised up the lake for 10 miles at about half throttle. No problems then or since. My advice: put gas and oil in your Honda and use it... sensibly, of course. Up here in the Sierra Nevadas we've had an unusually mild winter, so I've been fishing a lot lately... mostly trolling in our aluminum fishing boat. I've caught my limit of rainbow trout every time I've gone out during the last month (all of them 12-16 inches). By mid-day I'm usually down to my shirtsleeves and remembering what January and February were like in West Virginia. That's when I say to my self, "Self, you certainly did the right thing when you moved west 35 years ago." We do get an occasional picturesque snow storm, but our 4x4 SUV plows right through it. To all you snow and ice bound Montgomery friends back east, our deepest sympathy. Joe Kidd M15 #207 "Poco A Poco"

Thanks, Connie! My Monty is a 17' and my motor is a Nissan, but I'm sure the same principles apply. Now, as for the probability of no snow . . . I do live in Michigan . . . :-( --Craig ----- Original Message ----- From: <chbenneck@juno.com> To: <montgomery_boats@mailman.xmission.com> Sent: Thursday, February 20, 2003 9:37 PM Subject: Vibration Hi Craig, A few more thoughts from my point of view.
