The main reason for delamination is too low a density of foam (based on many threads on boat design). The foam starts to break down due to loading If the top layer is delaminated, you need to remove the whole outer skin. I would also take a core sample (about 1" in diameter) to see if the...

Suggest you start your own thread regarding your own boat.

paying marina prices for both labor and parts, you are looking at over $2500. if you do the work yourself, you are looking at about $750 for the dry break kit

being a sailboat, while there is a bit less fairing and you may not have to redo the non-skid on the foredeck working upside down underneath...... however, its messy and a PITA. much easier to re-roll the non-skid from the top while working in shorts vs having to try and hold up 3 yards of...

you probably have the problematic bat-wing manifolds. replace them.

Just provide power as indicated How do you know the 483 is accurate? Most hour meters are not accurate, and the are generally used for maintenance guidance

That would be more work than removing the top layer, removing the damaged core, gluing in new core, then 3 layers of 1708 vacuum bagged

Motor is 3/8-16 Bicycle stem threads are 5/16-24 Some air hose threads are 1/8" NPT The adapter I use with my mityvac is the one from my $4 lube oil pump kit

It's not sprayed in if it's laminated. It was core foam put in the mold then covered on (layer on the inside)

marine max owns a bunch of marine parts stores. heck, capital one got hit a few years back. hackers must die

did you check the alignment? (should be done every year)

skip the MEK..... go straight to grinding. figure 4-6" past every seam for tabbing...... then grind about another 4" further than you think

at idle in a barrel, only about 50-70% of the fuel and oil gets burned, the remainder goes out the exhaust and becomes sludge. most of the fogging oil goes out the the exhaust.

still not legal on an I/O, and the mechanical pump will suck fuel over 22 feet. so not needed.

FWIW, I have an outboard at 24:1, one at 50:1. Both smoke about the same at idle chain saws at 32:1, weed whackers at 32:1 and a moped at 40:1. They also do not produce much smoke I love the smell of 2-strokes That little extra oil in the fuel won't hurt
