Is it difficult to replace an onboard Onan generator with a Honda generator?

[magentawave]

I'm going to be looking at a Class C this weekend that looks clean inside and out and has low miles. Only problem is the existing Onan generator doesn't work. I don't know whats wrong with it yet but I was wondering if anyone has replaced an onboard Onan generator with a regular Honda generator? Are Hondas too large in size to get the equivalent watts? Are Onans smaller and fit in the compartment better which is why the motorhome manufacturers all seem to use Onans?<br /><br />Thanks<br /><br />Steve

will it crank? some have their own Battery.<br />1.Most Onans are made to cool from the bottom..changing to a Honda Might over heat it.if it doesn't get air.<br />2.the onan is (hard wired to the power panel) 115 volt system.<br />3.bad gas is usually what is wrong with Onans THEY must be run &amp; Loaded monthly-or the gas will gum up the carb.you might even have collapsed rubber hose from the tank to the Gen.<br />sparky1.in s.Va.

My favorite x husband just did it. He's not a mechanical genius and hates getting his hands dirty. He didn't have any problem at all.&nbsp;

I've never made the actual switch, but I do own a Honda 2000 gen. The Honda 3000 would be ideal for your purpose. it comes with its own battery and electric starter. It is very quiet and burns very little gas, and Honda reliability in their generators is legendary. Measure first but I would be amazed if it wouldn't fit. <br /><br />The 3000 will run everything in your RV (including the air conditioner) but not all at once. I think if you are at all handy you could do the conversion, if not I doubt it would cost to hire someone. <br /><br />The 2000 will fit and be easy, but no electric start and it won't run the 13500 btu air conditioners most RVs have. You can connect two 2000s together and get 4000, but that will cost you $2300 dollars total, and still no electric start. Bob

This sounds amazingly simplistic, but there is an air intake hose that sometimes gets blocked. Pull it off off the genny, then try to start it; before you put out any money.

You will need have the move install a honda genset in place of an Onan. Honda units are too tall, and running your exhaust would be quit coastly, hondas also have a remote fuel system mounted on them. Onan is a good unit. Try to find out what's wrong with it. If it's been setting around for any length of time, it may just need a new carb. RV tech since 74
