Not sure what I am going too do .

Owing 20 years .a 1984 Sea Ray . Not your typical Sea Ray ,
Sea Ray company known for cruisers
Since they owed Boston Whaler they came out with the Fisherman under the Sea Ray logo
Styled life a Whaler of those years .
Different sizes ( 21 - 26 ) & power packages. Basic fishing boats . ALL IO
Mine is the SRV 21 .
21 ft . 8 ft beam . Small cuddy cabin . Bimini top , Walk around . Called the Fisherman .
My model came with IO, 4 cylinder 488 Mercruiser . Frugal gas engine . Alpha 1
Lots of negatives on this engine but a 21 ft boat @ 35 mph was fine for me . .
The name Fisherman was changed too Laguna
.
Late eighties early nighties, Laguna was same boat as fisherman ,
Eventually they went OB still offering walk around ,cuddy .
At some point all Lagunas had OB center consoles .
Never fails comments at boat ramp . HEY NEVER KNEW SEA RAY MADE A WALK AROUND CUDDY . NICE

Original engine was done . Not sure what I was going too do , Covered
4 cylinder parts are hard to find, expensive
6 cylinders plentiful .
MOVING FORWARD MANY YEARS ,
Retired . . Purchased a 30 ft luxury cruiser . . Twin gas engines. 1 gallon per mile burn, I cry at fuel dock at weekly fill ups
After 3 years, Thrill is gone on cruiser . Not fun anymore
Never wanting too sell Sea Ray which sat covered at home .
Got the bug too work on Sea Ray that sits home Covered . CLEAN
At my fishing club a fellow member ( had for a project he never got too ) a 3.7 Mercruiser . 165 HP 17 hours.
Like new .
4 cylinder parts are expensive hard too come buy but only paid five hundred bucks , My decision was made
It was the cheapest way too go, truly a Drop in & go engine . .
When I removed old engine discovered the glass in engine room had movement ,. Hollow areas that I was able too push entire sections . Never had any outside cracks but clearly transom needs work .
Engine removed, gimbal removed
Started too cut out the glass were the gimbal was and once I removed outer shell starboard side, wood was rotted coming apart in my finders
Port side from gimbal opening glass is firm, no hollow areas underneath , (hit with mallet ) . all the way too gunnel
Starboard from gimbal opening too gunnel is soft .
Gas tank is located in middle of floor , Floor lifts , easy access . Wood on one side is trash
Cut it out and can feel wet foam with my fingers a short distance from were I cut wood sheet
.
A ledge just before transom held, batteries ( port side ) & trim & tilt motor ( starboard ) wood glassed over, , made small whole too check out what's under wood . FOAM wet .
Have no idea were there is foam but assuming all under floor
I am afraid too open a Pandora's box of no return . Stringers not visible . , up much higher guess its supporting floor .
I know best way is too lift floor . Re DO everything . I am not equipped too do this job nor do I want too do this job
Boat not worth more then 5 thousand in turn key used condition .
I am handy and most car & boat repairs , but am I entering a point of no return. questing if its worth it ?

CHEAP O GUYS on Craigslist are usually bad . Legit shops few and costly
Newer boats with OB are so nice but costly. Adding into mix my cruiser. Funds only go so far

If I replace transom and rotted wood Will foam dry out at some point ?
Can I make small pin wholes and pour liquid foam all around ?

A Simple rolling fishing cart, going too pier , surf fishing, getting rid of boats sounds so nice at times

THANKS FOR READING AND THOUGHTS . .

the foam will never dry out, even if you parked it in a desert for 10 years. and if it did dry out, it would no longer be flotation foam, since wet foam is broken down closed cell foam.

if the foam is wet, so are the stringers

to get the rotten stringers out, you need to remove the floor and the wet foam.

no sense doing it half-arsed

only way to do it right is to cut out the floor, remove the old rotten stuff, rebuild the stringers and bulkheads and transom. tab them all in. make a floor, tab that in. then drill holes to pour foam.

see the DIY links in the hull and restoration forum. specifically links 14 and 18

I agree do it right cut everything out and start over
try to save the pieces you cut out especially the stringers to use as a template

I found out something this weekend that I hadn't seen mentioned anywhere on here before about wet foam. Ants apparently find it irresistible. I am sure the PO having this thing parked under a tree uncovered didn't help either. If you have no desire to retain the boat, like Scott said - sell with full disclosure. When I went looking for a boat, I did not have a clue how to work on one and still don't. But I looked for a project boat because I wanted to do something with my boys that we could do together, learn together, and be proud of. There are people out there that will buy it.
