Had my just finished restoring Penguin Phantom out in Cockburn Sound the other day when an alarm started sounding, thinking it was the overheat alarm there were a few worried minutes until it was established that the motor was not cooking itself, so headed back to the ramp at low speed with everyone within earshot hearing the alarm , at this point a bloke with "30 plus years in boats" gave me a lecture on why my motor was overheating and how he recognised the alarm from 50 metres away and how I should just throw the motor away because that particular make and model were just crap anyway.
Well dude hopefully you or one of your mates reads this this cause your full of S&*T and a moron (I counted 9 empty stubbies in your boat not including the one in yr hand).
Many thanks to Andrew at A&M Marine in Mandurah who was good enough to listen to me on the phone and not only diagnosed the problem but was good enough to tell me how to fix it.
Turns out it was the 2 stroke oil pump alarm, the pump is disconnected and I use Pre Mix, however the electrics to the pump had not been disconnected and when a new alarm buzzer was fitted it was sending a fault signal.
The moral here is Beware of dickheads trying to big note themselves and do consult genuine experts.
