If the gen is not set up to run off the main ships tank I don't think it's made for that. I hope I'm wrong about the design.

Sparks are obviously an issue with any gasoline engine.This is why I have the vapor sensor alarm (Fireboy-Xintex MB-1),the blower right over the generator (that will run at all times with generator) and the fuel cap on the generator has an open (run) and close switch on the top. Not to mention I am going to crack the hatch open while in operation. Bottom line, you could say that it having the generator fuel tank in the engine compartment is dangerous, but if it is not running ,it does not pose a spark danger in itself, and the drive engine starters and alternators are spark suppressing.So the only time it is an issue is when the gen running and at that time the blower will be running and the hatch is open.Also, the generator will not be running while under way....Make sense?Sorry so wordy Mike

Not trying to ruin the project, but there is a reason diff types of gen's are made. It's all about safety and with gasoline engines, safety is number one.

I'm speaking from several years of experience having owned a very large marina and done everything from a tune up to a $1MM repair on Dave Thomas' Sea Ray 680SS.

Personally, I wouldn't go near that with a 300' pole. Better check with your insurance too.........................???

I own a Honda 2000i generator. Nice and light. Quiet. But not designed to be run in a closed space. I have two questions for you. How did you determine the temperature of the exhaust gas? And, are you sure a 2000 watt generator, rated at 16 amps max, can run a 10000 btu ac unit? And other accessories?

I started a deck railing ON FIRE by running the EXACT same generator you have too close to the ballusters. And this was outside. I'm assuming that it takes more than 180 degrees to start wood ON FIRE. And, I was running the geni in the Eco throttle mode, which is idling most of the time. Your generator is going to be at MAX while the ac is on. I think that silicone hose is going to melt.

I'm not trying to be a dickhead, but I'm really worried about this exhaust thing. I'm telling you straight up, the fire on the deck scared the pants of me. I couldn't believe it.

Good luck and please be safe!

You would have been better off and safer just running the generator on the swim platform, with a heavy gauge pigtail cord, since you're never running it while underway. Why go through all the hassle and the risk?

Michael,
That looks way to dangerous for a man with a new baby. I think you should ship the boat out here to me and I will test it for a few years for you. Free of charge even.

I think I agree with this, but I also respect the amount of thought that was put into it. If it were me (which it's not) I would only run it with the hatch up a foot or so at minimum.

Co2 censors in the bilge and cabin might be a good idea too.

I have other ideas about the exhaust too, thinking you could use a "venturi" set up to mix the (hot) exhaust gases with cooler air before it exits.

I agree, but if you are running the a/c, it must be hot out. If the hatch is up a foot in the air, or at all for that matter, how are you going to go swimming and get back in the boat? Unless you don't swim?
