Well fellas, I've read till my eyes burn and still cant decide wether to go with the optimax 150 or the E-tec 150. Sounds like the optimax is a little more complex with the extra parts (ie belt driven compresser and additional components, changing plugs yearly, extra filters) I have to wonder if some of this is hyped up because other threads stated opti and E-tec are very comparible. Problem for me is I dont hear any details on the E-tec other than "you dont have to service it for three years" So please lay your thoughts on me as to which is the better motor for my buck. Also the closest E-tec is 450 miles away as a package deal. I can get an optimax right hear in town on a new 18'6" fisher hawk186 sport loaded for 28,000 even. Thanks so much for your replys.they are greatly appreciated.
