    wanting to hook up a power system for running 240v appliances on demand of when i need it, i will be powering a minimum use like microwave , maybe other small appliances when i need to cook etc, but aim to run 12 v lighting and tv etc so can power this thru batteries, so generally i need a remote style system that i can start and stop from my cabin area for when i want to run the 240v or charge the batteries .
    what is the diference between a generator and a genset, can a normal generetor like a 5kw petrol unit that is electric start be used and plum the exhaust outlet thru hull etc or is there a problem with these style of units(apart from noise) in a boat, my boat is ali catamaran so dont really have a worry about the noise as it will be put into one of the hulls that are sealed from the cabin, and at most it will run for maybe 1 hr aprox for cooking time
    any experiences in diy fairly low budget setups would be helpfull, even the ones that didnt work to know from experience would be great...

    There is no difference between generator / genset in common use of language.

    Of course you could use a petrol genset with a dry exhaust, though that might be finicky to build on a smaller cat hull. You have to be sure that there will never get water into it when sailing.
    And of course you need a special ventilation (ex. proof ventilator) for the room.

    It maybe the better solution just to install a larger alternator on one main engine and a inverter.

    Regards

    There is a multitude of ways to go wrong permanently installing a portable generator inside the hull from carburetion, electrics to exhaust piping (unless you were thinking diesel). What is commonly done is to have an inverter and a small generator stowed aboard that can be put on deck and plugged into the vessel shore power inlet to provide AC current when desired.

    If being able to cook on demand is your main concern install a cng/lpg system. Flip a switch at the galley to turn the gas on turn it off when you are done. This assumes a proper installation with a dedicated sealed locker and other appropriate features.
