Assume it's 250 hours of work. Just the cutting and grinding is 25 hours
At 125-150 per hour shop rate. What corners are being cut?
If you want to do coosa yourself add $1000 to my estimate. It's $200/sheet compared to $40

To do it with plywood and fiberglass yourself will be about $1500-2000
$200 in wood
$200 in PPE
$100 in cloth
$300-500 in resin
$400 in foam
$300 in misc fiberglass supplies
$200 in sanding discs blades, etc
While the Volvo engine uses GM pulleys. You won't find them in an automotive equivalent
Either visit your GM industrial dealer or order thru Volvo

Your out maybe $20
your battery lugs were not cleaned with 150 grit sand paper
your battery clamps are wrong for a marine application

proper repair would be to remove the top, cut it apart, replace the core, reglass the top, re-gel or paint and then reinstall.
To each their own. A 52 year old marine motor would have lots of rust in the passages
Nothing special about the marine heads. They are just truck parts
