Which Generator for a 1992 300 sundancer?

[jdpromo33]

Hi everyone. Just wanted to get some advise on what kind of generator I would need for my 1992 300 Sundancer.

I will be running TV, Video game console, small fridge, radio, lights, water heater, AC unit etc?

Or is there another cheaper option?

It's my first real boating season and not sure I even need a gennie but I guess it would be nice to be able to power everything

Thanks

Just for clarity all the above will run fine off just your batteries except the AC. I have a 19" flat panel TV, Isotherm refrigerator, Stereo with sub, etc. and they all are fine on just battery power. I always run off the deep cycle battery and leave my starting battery switch off.....just in case I run my deep cycle to low. Never had to switch to it yet.

I have a Kohler 5E 5kw that was factory installed. You didn't mention a microwave or an electric range top but that would need gen power too. Installation cost varies, if you have to relocate the battery bank, or anything else, the cost goes up. I wouldn't rule out a 8 - 10 grand cost to have it installed.

I love the generator because I don't have to worry about battery power management while away from the marina for a long weekend on the hook.

As far as generator brands, I think the Westerbeke are more quiet than my Kohler because they run at a lower rpm than mine....though I have never had any real problems with my 5E. I just carry spare spark plugs and a water pump impeller.

With the excpetion of A/C and the water heater (which can be run off the engine coolant as well), you don't need a gen.

It's the high amperage loads- like your A/C, electric range, micro, etc. that have the power demand requiring a genset. Smaller A/C loads are better accomplished through inverters and "upping" the size of your house battery bank. A lot of boater have both- no need to run a gen to power a game console, tv, etc. In fact, gens should be run with moderate to heavy loads.

In your case, a 3 or 4 kw unit (low CO) is perfect. You're limited to 30 amps at your panel, and probably don't need larger, anyway. Expect to spend about $8-$10 for it professionally installed.

Thanks guys, this is great info. I presume that with engines running as well, then power is not an issue

I'm new to my boat so don't know it's characteristics yet.

I think for my first season I will do without a gen and see how it goes.

Agree with both tobnpr and Quint4. Much depends on your use and comfort level desired. If you go with a gennie, get an 1800 RPM LoCO unit. Those things are a quiet as a church mouse.

Hang on he says donning Kevlar and Nomex suit.....

You will get all kinds of flack if you even mention running a Honda 2K on the platform despite many do so successfully.
