the Honda 2H long shaft is a great motor for the M15. my opinon is a 3hp motor would be a perfect fit. anything greater is more motor than necessary. the limit of all 'small' motors is none have a fuel pump so one must fill the tank while hanging over the back of the boat once an hour ... IF ONLY a building would make a 2-3hp motor with a fuel pump!!! dave scobie M15 #288 - SCRED visit Scred's www-site: http://www.freewebs.com/m15-named-scred --- On Wed, 8/6/08, Lou <capnlou@ec.rr.com> wrote: From: Lou <capnlou@ec.rr.com> Subject: M_Boats: M-15/Honda BF5A To: montgomery_boats@mailman.xmission.com Date: Wednesday, August 6, 2008, 10:44 PM Does anyone know if this 5 HP Honda engine ( BF5A) will work well on my M-15 with the lifting bracket mount. I believe it has a short shaft but I think my current Yamaha 2.5 also has a short shaft. Is the 60lb weight going to be a problem? Thanks... Lou (M-15 Still The One)
