I'm task with buying a small HP outboard engine ( under 10hp) for a 14ft jon Tracker boat. I was looking for the simple and easy to fix 2stroke motor. Any pros/cons for getting a 4stroke job.? Once again I was looking for the best $$$s spent per HP and easy in repair. I also have no problems with pre-mixing the oil & gas.Any comments? As a side question have anybody had any bad reviews on buying a used marine outboard? and/or can reccommend a good engine rebuilder that provides at least 3-6months warranty?
