Let me get this straight...
You had some work done on your boat and it was $370.00.
Whether it fixed the problem or not consider yourself lucky that someone even looked at it this time of year for $370.00.
Most people wont get off their ass now a days for that kind of money.
It's a boat right?
Anytime I have anything done it's a $1000.00 minimum, I just plan for that and if it's lower well then I got the "deal of the day"...
