Thanks Watermann.
The "bag o peanuts" idea is a couple of plastic bags, stuffed into mesh laundry bags and secured under rear. out of site, but easy to remove for things like changing the water separator fuel filter, etc. just a extra couple hunnert pounds of float, so the hull would be a bit higher and more level, should anything get real ugly. Precious cargo on board, ya know? I am looking for any downside I may not have considers, like, if you do that, then X will likely happen. Where X = something bad.
Not some permanent mod that would be a pita to deal with at any point in time, and more convenient than permanent foam under there.
I am making few decisions on things other than what I know I need to replace. Purchases are as needed at this time - since I cannot see the full condition of the hull yet. I know I will need new gauges, regardless. Has a speedo that is way too optimistic - unless I hang a 150 on the back. ( Not likely. ) And the tach was an automotive tach, and is not accurate. So I need a boat tach for 12p anyway.
If I do an engine upgrade, it will likely be a 115 crossflow or 120 looper. But 85 is certainly enough power for fishing, as I get 35 indicated with the aluminum 19P prop. I have a 17 ss that will go on. if I end up swapping out the motor, may bump it a bit on the power.
I try to not spend unless I need to, I have most of the mechanic tools I need, but the tools I need for woodwork are MIA. They were purchased 4 house remodels ago, back in the last century... Reckon I will find them now that they have been replaced.
Got a used DeWalt 950 XRP, for less than half of new, and it was mfg Feb, 2014. A OK Circular and old craftsman scroll saw. . All for less than new harbor freight sh- stuff. No tools - no worky on project.
Once I have done all the prep work, rivets, gluvit, and such. and start in on getting the deck back in, I will know if i want to do a 'keep is close to original config, or go another direction with the seating, helm, etc. Tempting and lots to think about, but I have to weigh the practical and cost against spending too much on a 40 YO boat.
The bimini, otoh, will be the LAST thing I will take off, and the FIRST thing I get back on the hull. South Texas heat. It keeps the sun from turning the hull into a 450 degree solar cooker with me being the main course.
Cover a boat? Sacriliage. Why all that UV is good for it. Sterilizes the germs. And whats this 'rain' thing you speak of? Is it anything like that mythical thing called "snow"?

All things considered, a cover is the cheapest / best thing you can do for a boat, if you can't garage it.
I do have a bit of a self imposed timeline. Mid Oct. for re-splash. This boat will never be worth even 6 - 7 K should i want to sell it, so i am not gonna sink a wazoo of cash in it. I am budgeting about 2K for new parts supplies, etc., but hope to finish for about half that. I want Seaworthy, safe, clean, functional, and pretty enough to not apologize for.
Hoping to end up with the functional equivalent of a much newer boat at a fraction of the cost. As I see it financially, owning a boat its like finding great amusement and joy in flushing paper currency down the toilet. But I figure I can have just as much fun with 1's and 5's as with 20's and 100's. Wheeee! flushhhh . . .
My firsthand experiance of a money pit with a propeller - I had a 1957 Piper PA-22 that I bought for 14K and added another 7K of avionics. Required inspections, and compliance with A.D.s cost another 6K or so over the next few years. I flew the tar out of it, till it needed an engine overhaul. Guy doing it dropped dead of a heart attack, and one of his workers stole my prop, cowling, and some other parts. I ended up selling it for 7K. Just like a boat, but little bit more above sea level.
Oh well, rambled on too much here.
Still trying to fing how much Gluvit to order. 2# enough? Hear it goes a long way, but I don't want to get 3/4 done, and run out, and would prefer to not buy a second can I won't need.
5200 - someone fill me in about this stuff. What's is used for an why? I read the destructions - but that is less than the practical applications I am sure.
Thanks.
