Onan Marquis Gold 5500 in a 300le?

Has anyone put an Onan Marquis Gold 5500 in a 1991 300le? Can anyone tell me if one will fit? Stock is a 6500 gas.

Thanks, Sebastian

Just installed one in '83 310... If your bay held an Onan NH 65K it may fit. They apparently cross connected my remote start switch with the control panel engine battery condition switch though. Otherwise an unwelcome large expense but a nice improvement over the original.

I had a chance to look at mine...I think the main problem is that the height is 17" and the 34" long. I'm looking at fabrication because the existing generator is not as long or tall, and fits up into a notch in the floor. Mine has a cable and lock that appears to rotate the generator down for servicing that I would need to modify.

Sebastian:

Be care with the winch mechanism. My was broken by generator mechanic and I had to do a lot of research to find a way of getting it repaired. Not sure if the new one would fit but if you lower the current unit carefully, you can measure the space. jim

Important: New bay floor openings are required.

My unit was installed by a Cummins-Onan repair shop. They had to customize the wiring to the unit and cut some substantial new vent openings.

I should have made it clear this was not a do it yourself job for me!

The attached install guide may help your decision.

Thanks for the great information. Did you end up removing the hinged lift, or did yours have one? Would you happen to have a photo of the finished install?

Thanks, Sebastian

I picked up the Onan marquis Gold 5.5 generator over the weekend, and dropped it off at the shop that is working on my rig. They do fabrication, so well see what they come up with and I'll post photos of progress.

I got it installed today! What a chore...I had to modify the cover, cut down the muffler, build new brackets, but it's a nice fit now. I will ire it up and get it running next weekend, as well as post photos.

So to clarify... you had someone else do the diesel generator install, plumbing, and wiring? If so, how much did it all run you? I am looking at doing the same.

I got some help from a welder installing mine- cost me about $250 plus the metal from Home Depot. The generator I got is gas not diesel. I did the wiring and hooked up the gas line on my own...not too hard.

Here is a photo with the cover modifications. I had to cut down the muffler and the cover to fit it up inside the space I had, otherwise it would have ended up much lower. After you get the original out (you can use the leveling jacks to lift up the back end after blocking the gen off) then pull it out. You weld in one L bracket with a tab for the rear left gen bolt, and weld or bolt one vertical for the front left. I cut part of the back right out to weld in a horizontal support for the back, welded a piece across the top, and another horizontal drop down for the front left bolt. Click image for larger version

Should have realized that when you said Marquis.... Sorry about that. I have a Marquis as well (LP), but am looking at replacing with a diesel if able. Anyone know if someone has done this for a diesel pusher?
