Since the boat does not run inverted, then as long as he can get enough muffler pressure it should work. The distance is not anymore than when a model aircraft is pulling fuel from the back of a nearly empty tank when pointed straight up.
So should I just run onboard glow and a hotter plug? Maybe fuel draw isn't the problem, but I don't know why it won't stay running with glow disconnected. It ran with glow disconnected just fine on the stand and never flooded.
