Re: About the time it takes to fix engines
There is so much wrong here I don't know where to start. I'll start w/ your engine problems.
1. Exhaust manifolds don't get cleaned. They get replaced every 7 years. Risers every 3. If one exhaust hose was bad, they all are bad. Replace them before the boat sinks.
2. Your fuel is now a year old. I hope it was stabilized.
3. Your engine problems are most likely fuel related. Bad gas, water in gas, fouled carbs.
4. An intermittent short at the distributor could also cause the problems.
If a yard has been working on your boat for a year and hasn't sent you a bill I'd be asking myself how do they pay their mechanic. Next I'd be looking for a new mechanic. This is rocket science.They should be able to diagnose and fix the problem inside a week.
