ETN550: I would love to see the 701 battery tray mod, just bought a new 24V battery for mine a couple of months ago.
Also on the two MEP-016D's I recently bought, the one that was done by a contractor has a Walbro FR series fuel pump on it, the on that was done as field job has the standard Facet GoldFlow. Have you ran across the Walbro's on any of yours?

Ike,
I have not seen a walbro on anything. walbro is a large name and does supply some oem to car companies. The Yanmar only needs a good gravity feed so any pump that can get the fuel there is good enough. Is the Walbro 24 volts?
Following are some pics of the battery tray installed on a 701A and the mods to the cover. The noise is not noticably changed, I think in part because the battery and fuel tank are behind the panel that gets modified. It would certainly be possible to cut down the screen and insulation to more accurately only remove what is in front of the battery.
This is the new tray for the 016B same as 701A just a different color
After removing the existing tray and the round post battery terminal ends The tray is bloted in using the existing rear holes and some tube spacers to offset it.
Two holes are drilled through the front aluminum frame using the tray as a guide
Batteries slide in from the front and are held in place with a top clamp. The existing wires are used and of the 11 I have done I have not yet had a wire that was too short. Sometimes I have to bend the terminal end 90 deg to get it to line up better with the post on the battery. Some of the first units I ever bought came with the green knob disconnects. I have been using them ever since. Note that by having the disconnect in the jumper cable it is possible to open the disconnect, jump the batteries in PARALLEL with a set of big Radio shack Alligator leads and then charge both batteries at once with a 12volt charger or maintainer. I like that feature. Remove the Alligator clips, close the green knob and instantly back to 24vdc!
the battery is a standard lawn and garden one. I use the lowest cost ones and they do okay. I have seen amp ratings up to 400+ in this same size case.
Drill out the small rivets and the screen and insulation comes out easily. The cover is about 2 inches deep and the new tray needs about 1-1/2 inches into the insulation.
I have to notch the cover to clear the bolts on the tray and to accomodate the extra thickness of the tray up against the lower frame. I could make a design where it all goes inside and I have done so with other versions but they are too complicated to make. I like this design best.
Top view with cover on. Easy to reach the disconnect knob. The knob can also be reached from the side cover.
All buttoned up.
