F Q these folks are giving you good advice on this one near as I can tell. Basically save your current motor even if it isn't working so you can upgrade the 220 as you go along. If possible find out what is wrong with current motor and fix it instead of buying 220. It seems like the price is right I don't know how you could lose on that one. You can get a trailer on airboattrader.com and you can get more advice on here than you could ever decode and use. You have to be careful what you ask on here because opinions are offered freely and sometime sthe really good advice given, and I mean that, actually overwhelms the asker to the point of actually stopping the project.
You will never have access to as much quality information anywhere else but here and the price is good also. SO GET GOIN, GITTR DUN
