I would think you would want YOUR cabin VERY cold, if you know what I mean.

Tough to run AC on 12v alone that is why most have them hooked to shore power.

However if you go that road (12v) I would add some batteries and run them through one engine (might want to get a bigger alternator) so you can idle it to charge the battery. If you gen up a Bullet space might become an issue. I know a v8 is overkill to charge batteries but the AC will suck up any battery set up you have then you need to run an engine anyway, be it gen or V8.

On my pig the two Cruiseair AC's run on shore power or on the diesel generator only. Trying to run them on an inverter through the house batteries would be to demanding on them and I have huge battery banks.

Just my opinion.

How much your honda weigh?
That is 100% backwards logic. ALL Marine gas generators have spark protection just like the gas engines do. Almost all diesel gen sets do not (I've only seen one that meets the USCG regs but I've never seen one actually installed)

A stand alone Honda Gen set won't have the protection... plenty of people use them, it isn't 'safe' but if you are careful I guess you can get away with it.


On the A/C note, I have looked at them and the one thing that kills the deal is the lack of being able to use them when the boat is on the trailer. Does anyone make a unit that would work without water?

Seems like getting the cabin cooled overnight before you run then just keeping it cool would be better than dropping the boat in the water with a hot cabin and trying to get it to cool down.

Oh yeah...i think I recall a long thread about this some time ago.

would you rather have a diesel gen that had spark protection over a gas unit...on a gas boat? or would you never mix and match no matter what?

I would be tempted to engineer a self contained water reservoir system with a radiator to connect to the a/c water lines so you could run the a/c on the trailer. Just roll it out of the garage and hook it up.

This would be great..that way you can use your cabin on the way to Poker Runs at the rest areas

not sure of the weight of it, but i put my honda generator on the tip of the bow when running...with exhaust pointed outward. You can't even hear it running when it's up there.

Says the 12V unit is 48 amps - that is a pretty heavy draw to sustain for hours.
