Check your floor thickness. 73-4 were 1 inch. 75 up were 3/4. Area on all were 1 inch above engine as I recall. All were marine grade. For areas that aren't resting on a floor supports. Make a patch for the area to be repaired. Draw it's shape on the floor. Then draw another line about 1-1/2 inch inboard of the patch line. This will allow you to remove damaged area without damaging the insulation below the floor. Set you router to the floor thickness. Cut to the inside of the inter line. Set your router to 1/2 the thickness of the floor. Use the router to remove the area between the two lines on the floor. Next repeat this to the bottom of the patch floor panel. Use a good water proof wood glue. Install some flat head screws to hold the patch while glue sets. I left the screws in place. Haven't found the photos yet. This proved to be extremely strong.

Thank you. Makes perfect sense. We're the 3/4 boards in 78 true 3/4, or
will I have to adjust slightly for new lumber dimensions?
Also, have you ever replaced a whole panel? I'm curious have challenging it
might be.

Replacing the whole panel is not hard assuming you have everything that
sits on top of it,anything that passes through it and anything which might
be pinned to the underside removed. Just pulling screws from there.

Thanks Matt. Mine is completely visible at the moment as well. (Minus the
bathroom and closet. The panel which runs from the door to the kitchen is
in the worst shape, but also houses frame bolts. In this case, i plan to
patch vs replace. The center of the wood is in fine shape.
Some good news - I was able to get the Onan running very well!
I'll contact Forest now.

To remove whole panels (I removed all of them) an impact driver is almost a necessity. Those screws are not stainless and have galled in the aluminum and are hell to remove without an impact. The impact makes quick work of them. It's an indespensible tool. An air compressor with a fine blower nozzle helps a lot as well as the screws are countersunk an the heads are filled with years of sawdust and debris. Blow them out after picking at them with a pick to ensure that the to driver fits all the way down in there so you don't strip the screws.
The rear panels are also glued down with panel bond adhesive.
The rear panels extend under the wheel wells so they have to come out to remove the floor panel.
If you can cut and route a panel to fill go that route, or epoxy, either works.

For those of you who have not used an impact driverl, it is totally
manual (no air compressor required).
You place it on the screw and strike the end with a hammer. It
simultaneously keeps the screwdriver head securely seated in the screw,
while also providing the twisting force to loosen it. There is much
less chance of stripping out the screw head due to the seating force
that is equally applied.
They are a 'must have' tool for old motorcycles, and mine has earned its
weight in gold over the years. Well worth the small expenditure!

Having been down this road with lots of seized and corroded stuff. I can tell you that if you are working on old stuff, it is worth your while to hunt up and acquire a KD Tools 1140. If used as directed, it will loosen any screws that are removable and maybe even a few that are not....
They also work well without high pressure air or electric power.
The real advantage of the KD version is the heavier body. This makes more of the twist go to the bit and not your hand. If you are as old a some of us, you remember KD tools very well, but they are now GearWrench/KD so finding them may be at bit of a problem. They also are not as cheap as they used to be. Just like everything else.

Those bits that come with the inexpensive Hand Impact drivers are pretty
much worthless. I have two hand impact drivers, a 3/8 drive, and a 1/2"
drive. They both were purchased back in my motorcycle repair days. The 3/8
drive has the square drive projecting from the handle, and bits that fit
onto the square drive like a socket. They are very high quality and hold up
very well.
The 1/2 inch drive has a chuck that fits the square drive, and the small
bits go in the chuck. The small bits are of poor quality and break
frequently. I might consider them consumables. Lots of spares are needed.
The main thing to remember, is to keep down pressure on the handle, and
don't let your skin creep up onto the hammer striking area. Make sure to be
square and plumb before you strike with the hammer. They will take Japanese
motorcycle case screws out when nothing else will work. Be sure to exactly
match the bit to the screw heads. There is Phillips, Reed & Prince,
Posi-drive, and possibly more, as well as U.S.S., D.I.N., and I.S.O. tapers
on the heads.
What I know.
