I do it all myself. I've owned my boat ('89 centurion falcon) for 20 years. These inboards are incredibly reliable. Oil change and impeller every year. Outside of that I've replaced my starter 2 times, new dampner plate, new seals and bushing in rudder box, new steering cable, new shift and throttle cables, replaced all hoses, and a stringer repair that had to be dealt with. I did do several upgrades over the years that include new propeller and shaft, upgrade to electronic ignition, and added Stargazer. All in all i'd say that was pretty minimal over the course of 20 years. It runs very well and in my opinion it skis very well too. I don't think the wakes give up anything to the newer boats. Tracking isn't as good but I mean a little input from the driver solves that. It is a wood stringer boat and that is it's downfall. If i can upgrade to a newer boat with composite construction for a reasonable price I would consider it, but at this point the boat owes me nothing. I could redo the stringers and floor, and foam for relatively cheap and enjoy this boat until i'm too old to ski anymore. Not bad for an original purchase price of $7500 for a boat that was 12 years old at that time.
