Yeah, I have sort of decided what to do:
First off all, I decided NOT to tear off the floor / cabin sole
and then cut the tank open to coat it properly.
That would have been the best solution except for the horrific amount of work involved and the expenses.
As I am not retired and don't have a shop full of tools, I would have been forced to hire people to do quite a bit of the work.
The going rate around here is $55.00 per hour for marine
So that solution is out.
Decided to sand the inside of gel coat surface as much as I could, using only the inspection
holes, they are 5" X 5" and there is 4 of them.
I can get my arm in there and have started the sanding
After the sanding
and acetone washing
, I will coat the gelcoat
with West System epoxy
applied with a foambrush.
I should be able to get 90% of the "floor" in the tank done and parhaps 80% of the walls and hopefully 60% of the top (roof).
Also cleaned off all old cauliking and sealents, and instead using chemical resistant rubber gaskets for cover-plates and plumbing
In addition I will use higer "grade" filters on the drinking water
system...Got one yeasterday that looks pretty promising: MATRIKX+CTO/2/ model 32-250-125-975.
The whole project
should cost me about $50.00
IF I still have taste of smell after doing the above, then I will simply install a small dinking water
tank and use the existing pump, hoses, accumulator, etc.
There is plenty of extra room on the boat for a 20 gallon tank, or even 2 x 20 gallon tanks
, but that will eat into my storage
(Where the 8 cases of beer
go for the long Exuma cruises..
I did consider inserting bladders in the tank, but due to the shape and the baffles and angles, etc It would not be practical.
I should be done in a few days and will report back.
