Hull is all primed now ..ineedcto enclose engine bay and build a hatch .. how did you guys enclose one?...

deck inspection and replacement
 

Well I knew there were some bad spots around the t top legs so I decided to tear the top skin off and replace with foam core.. this is were I am at now.. I removed the tank and found some bad spots will weld them up as that is all about five little spots about 1.00" around... I am debating on removing forward box and moving tank far forward.

I will a agree a twisted wire cup brush on a grinder made the balsa core
come right off

If you're planning on twins on a bracket, I'd definitely move that gas tank as far forward as possible. The CG on the I/O's is further forward than on the OB models even when they were hung on the transom, so a bracket will move the CG even further aft. I'd prefer a couple of 50 gallon tanks so you can burn off fuel in the aft tank first, or not even use it except for long trips.

Inhave two 70 gallon tanks i can put in the boat but i will have to remove the fish box and loose storage.. When fishing i usually have a bout 200 pounds of fish and ice coming home.some times more.. Would that be enough .weight forwad. I have a bracket about 175 lbs and twin150 mercs 99 carb outboards...28 " setback Iwas going to move fish box to the stern. But then the weigt would be in stern. Here in pc we run 100 miles round trip to our fishing grounds.

Here is the rest of the glass skin pulled and played new scale of 1708 down then I vaxumm baggws yje foam down. My vac pump died while glassing so I had to improvise...

foam core
 

Here is the foam

Finally have fuel tanks blasted and coated with 5811 belzona immersion grade.. I first sanded with 40 grit and cleaned with ppg alum cleaner.. Then i white blasted all the seems and hard to reach areas.. Cleaned again. Let dry then coated with belzona... 3 coats on bottom. And three coats on top then 2 coats on sides.. Also finished coating alum transom bracket supports.. Once installed i can finish up the floor cause theses brackets bolt to the deck as well..

this stuff is very good at keeping corrosion to a min. I have used this in some of the most corrosive environments. Such as Large heat exchanger plates for Gulf power electric. and For all wastewater applications for coating of wastewater pumps. the pumps are cast steel and this stuff really protects these pumps from corrosion. Belzona can be used for concrete, steel and Alum..Oh and as far as elongation for expansion and contraction. It is excellent..
