HELP - Flushing a 3 cylinder Mariner 50hp
I have a 3 cylinder mariner 50hp (Clam shell) outboard. Unfortunatly I can't find a big enough barrel to flush the outboard in as it is fitted with hydrofoils. I went out and bought some flush muffs. However, the engine will start fine when the whole boat in in the sea but it will not start when only the flush muffs are connected when the boat is on the trailer.
Is this just a fluke or is there a float switch/water sensor in the leg to prevent the engine form dry running?
