Default Suggestions for a generator change (diesel vs gas)

I have given up on the generator that came on my boat. It is a 3.5kw, (Id rather not name the brand.)

In 8 months I have been able to put put 50 hours on it and thats using the boat a lot (lucky to be on it almost every weekend.

In this time I have gone throw 3 belts, 1 ECU, 2 capacitors. I just replaced the third belt only to have it run for 20 seconds and now it suddenly just stopped and its trying to start on its own.

I have room to put in a 5kw Westerbeke or a Kholer, Kholer being louder than Westerbeke. Out of both of these which is better?

Having said this, the big question is wether I should change to a diesel generator as I have a 15 gallon tank that was previously used as an auxiliary tank for 2 stroke oil....Since I have repowered to four strokes I might be able to use the tank for diesel.

So, is this not the right thing to do in order to open my possibilities for a much more reliable generator? are small diesel generators in the 5kw range much more reliable than gas???

any suggestions will be highly appreciated.

Diesel gensets are the best. They are more durable and less problem all the way around. The problem I think you will find is that to get a "real" diesel generator - you will be looking at serious weight and serious money.

The kick is to find an 1800 rpm diesel instead of a 3600 rpm diesel. This is where I think you will have trouble. You can buy a 3 or 4KW diesel generator on the cheap, but it will be one of those 3600 rpm units that is just loud. Conversely - my old Kubota 15KW unit would run 6 days straight without being shut off and only burn 70 gallons of fuel. It would sing you to sleep with that low tone.

I know that there are Kubota 3 cylinder units that meet the specs and are probably 8KW. That's a bunch of weight. You probably need a 2 cylinder and I don't know if they make one that small.

Good luck though!
