I have a 2015 225 Pro XS (Serial #2B122654) that runs out of warranty next month. All cylinders still test perfectly and I haven't had any problems with the engine but since I'm approaching 800 hrs I'm thinking about repowering. Anyone know the cost of getting a new powerhead (not a rebuild) if a worst case situation arises in the future? Or will it be impossible to get new factory powerheads given the transition to 4-strokes now?
