Kevin McCready 83 Posted March 26, 2022 Share Posted March 26, 2022 The engine cranks but won't start. It happened rather suddenly. It's a Nanni 15, 2 cylinder 2-60he Does anyone know if the glow plugs run off the starter battery or off the house battery. I'm not on the boat now and didn't think about that until I got back to shore. A friend helped me spray ether into the air inlet but that didn't help the firing. I thought I'd replace the fuel filters to see if that helps, but I could be on the wrong track. We just discovered there are two fuel filters, one on the intake side and one on the overflow to take fuel back to the tank. But the intake one (see picture) appears to have a screw on glass at the bottom. I haven't fiddled with it because I want to know what I should do first. Any tips would be appreciated both on the failure to start and on the fuel filters. Would diesel bug cause these problems? Quote Link to post Share on other sites
