I currently have a Westerbeke 5.0BCG, which is a carburetor generator, built in 2007. The generator preformed ok, until I installed AC in the houseboat... and it has never been right since. So now it is time to step up to a 10kw, and I'm looking at the Kohler 10EGD-Low CO and the Westerbeke 10.0 SBEG Safe CO. They are both similar in cost. It seems that the industry just seems to use Westerbeke, but I have had nothing but problems with the one I have. Not to mention the parts are a rip off, seriously $20 for a spark plug, $35 for an oil filter, come on! It just makes me shy away from Westerbeke. Is Kohler a bad choice? Both are fuel injected and apparently the carburetor is the cause of the delay when the AC kicks on... Any thoughts would be appreciated.
