Question 1
Just wanting further advice on possible cause of engine buzzer going off continuously when we put the boat in the water this drove very nicely but then stopped and couldn't restart the boat as it did not fire. We had to get towed back into shore, We did start the engines again when we got the boat home. What would be your recommendation to go over to try and eliminate this problem I am in the progress on reconditioning them all for carburettors. What would cause the engine to shut down. Just wanting to know if I should be looking at other things.
