when i turn key to on position I only get 1 beep not 2 like normal gauges on dash dont engage. Engine will turn over but dont start. It had been doing this intermittently but know it pretty much is out of commission. Took it to boat repair shop 2 hours away they had it for over 3 weeks brought it home put it on the fake a lake started it let it run for no more then 5 min. turn it off tried it again same problem. Oh by the way paid boat shop almost $1400.00 all labor no parts. any idea's thanks
