Formula PC 29

I purchased this boat two years ago from a friend. The boat needed a starter, so I paid a mechanic to go through the boat and make sure everything was alright. The right motor was removed and the bilge was pressure washed. Both starter motors, alternators and wiring harnesses where replaced. He also replace something on the exhaust, not sure what it was. When he installed the motor, it ran for five minutes then stopped. The left motor ran fine with no problem. He said that there was a problem with the right motor, but it was never investigated any further. It had taken the mechanic all summer to do the work, and to be honest, I lost interest in the boat. It sat all last summer, and I moved on to building a house and have no further interest in this boat. I paid $18,500 for the boat and spend $3,800 with the mechanic on parts and labor. Hopefully my loss will be somebody else's pleasure. I have never put the boat in the water, but my friend ran it the summer that I bought it from him with no issues other than the starter that I had replaced. As for the right motor, I have no clue what is wrong with it, but I would suggest either looking at it before you purchased it, or plan on a major repair cost. I never had it diagnosed and the mechanic who worked on it, never returned to fix it. The boat is all together right now, but does need some cleaning, as it has sat for 2 years. Arrangements must be made to move boat by winning bidder. Storage is not available.
