Replacing Generac gen in 2001 Marlin

I bought a 2001 Marlin without the 6.6kw LP Generac generator in it (got a great deal). I bought a new 7.5kw LP Generac to put in after checking bolt patterns. Unfortunately I found out the oil fill and filter are on the wrong side so I cannot use the new generator. Now I am trying to find anyone with a 2001 NRV that has a 6.6 LP generac and could give me a model #. I called Generac and they couldn't help at all. If anyone knows a model # of a new generator that would fit that would work too. Oh and I will have a new Gen for sale soon...

Thanks for any help folks

I previously owned a 2001 model with the LP Gen. It wasmodel 9734-3, Series NP-66LPG. Hope this helps.

Hi Mark,

I was wondering (sometimes that can be dangerous) can you get a new mounting plate for the new generator? It should be replaceable. It may require some welding but better then taking a bath. If it will fit in the hole someone should be able to modify the mount. Need to find a good welding shop.

Its not the mounting that is the problem (the new QP75LP fits in the spot just fine), its the frame rails that block access to changing the oil and filter. According to Generac the only LP model that had maintenance items on the front end was the 9734-3 NP-66LPG (I have called them 4 times now and honestly they seem completely unwilling to actually look anything up, since they answer immediately and always with a negative).

Since I am sure I can't be the only NRV owner that has to replace the generator I know there has got to be something out there. I have called Onan and Generac, Generator Joe (got no answer and no call back), Visone RV Mart, 3 RV salvage yards and 3 local Generator sales stores. So far I got no idea what to do yet.

Thanks Folks
Mark and Liz

National also offered a diesel version as an option in 2001. I don't recall if it was a Generac or Onan. Might be an option although would be more expensive than the LP. The LP is much louder than the diesel.

I have heard now that Onan makes diesel gens. with oil filters at the back but accessable from underneath thus eliminating the oil changing problem. I have not been able to verify this yet, and I don't know if the generator itself will fit in the space available... If anyone knows anything solid, I would greatly appreciate it.

Thanks,
Mark and Liz

Hello again Mark,

After looking at the 2 generators they appear to be almost identical. They both have access to the oil filter from the front. If the filter is the only problem is it possible to use the shorter (smaller) filter on 6.6Kw on your new generator? The smaller filter may allow you drop it low enough to get it out. Or would it be possible to raise the generator just enough to gain clearance?

Mark,

One other thing occurred to me, do you have the shock mounting kit? The vibration dampeners may raise the generator enough to give you the clearance you need.

Not really sure if the shock mounts are there or not. My MH is at Camping World getting quite a few things done (installing gen was only one thing) and they are 100 miles away. I have been talking with their mechanic about trying a diesel gen in it and he seems to think the Generac will fit with a couple small modifications. Its very aggrivating to be trying to find something to fit when it isn't here to check things out.

The Diesel gen seems to be a little cheaper actually than the LP from what I am looking at.
thanks,
Mark
