How do you get to the nuts to remove the sidewalls? Were they bolted into the deck and then dropped onto the hull?
.

That is different than my 32 but my friend with the straight bottom 37 just had his interior done last year and it has the same side panels as yours.
Marine/Boat Upholstery ? HYTECH Auto Trim ? Automotive Upholstery, Window Tinting ? Car and Truck Accessories did the work.

I believe the back one is accessible through the bilge. The others, you may have to take out the access door on the bottom and speaker. Some have added a speaker higher in the front for accessibility lol

You have to tape a ratchet wrench to something that is a couple feet long and go through the speaker hole.

Can you go through the speaker hole to get everything on the bottom loose and then pull the bottom of the panel back to get to the top ones? If it isn't open behind the panel, you could always add more speakers.

Bilge is solid across with not access. I'll remove the access door tomorrow.
I'll try the speaker holes. I just put the 8's in last summer. Before there was only 6.5's in there so that must have been a bitc# if that's how they did it.

That's a damn good looking interior. It appears they removed and installed it without making new access holes. Encouraging.

It also appears that his "Loincoin" floor has also stained. Which boat is this? I think there are only 3 37' straight bottom boats. Power??

I think there might be 5-6 straight 37's. It used to be tfarmer's boat and he bought it from Fastboats. Anybody Looking?

My friend Geno bought it from Timmy almost 2 years ago. It wasn't listed at the time, but had been about a year earlier so I put them in touch and the deal got made. It has the original 500efi's with about 300hrs now. The floor was redone with seadeck like stuff right after the interior. Our slips at our LOTO condos are right next to each other.

The best way is to send a small person/child up through the storage access at the floor, with the correct size ratchet wrench. I'm 6'2", and I was completely inside of my gunwales a couple times when I was installing the stereo.

I had to crawl in mine and use speaker holes. It's a fun job
