HELP - Flushing a 3 cylinder Mariner 50hp

Hi There,

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?

How are you trying to start it? I've never had a problem starting one of those on muffs.

Might be worth sticking a rag into the prop centre to restrict (NOT block) the exhaust a bit to simulate being in water.
Need spares,consoles,consumables,hire,training or even a new boat?

One other thing: My Honda used to act as if it was in the arctic when flushing in the driveway. Took a lot more choke than when it was in the water (flushed the motor after driving home, so it was out for a good 3 or 4 hours.) Not sure why that was, but there you go.

Take the foils off and use one of those blue plastic drums with the end cut off.
You shouldn't have any trouble starting it on muffs tho'.
