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"
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....
