Supposed to just be riveted together. Based on my own scraping and cleaning, I think there may have been a thin bead of better quality sealant applied at the factory right before they set the top on the bottom, but it was only on the outside facing edges.

Prior owner applied liberal (sloppy) amounts of a clear silicone adhesive. It was total, utter crap.

Wow! big props to you sir! I have an 89', same color, same motor.

Q: How difficult was it to get the exhaust out? From you pics and what I've seen on mine, it looks like just the four screws in the transom and dissconnecting the rubber. I'm assuming the beauty ring is also siliconed on.

Inside - one clamp on each 4" exhaust vent, hose was stuck on pretty good, but nothing that a few grunts couldn't take care of.

Outside - 6 screws on the 4" exhaust, and it was adhered to the boat with whatever strong sealant they used in 1988 - it was NOT just silicone, but a hybrid silicone-epoxy type substance. I used a razorblade and a scraper to cut down next to the exhaust ports and crack some of the material. It actually came away from the metal easier than the gelcoat. Took me maybe 45 minutes per exhaust port to separate the through-hulls from the hull. Once I had it sufficiently loosened up, a rubber mallet applied from the inside allowed me to push it out the rest of the way.

Was a good weekend to get some work done. Got all the paint sanded off, and started working on bringing the finish back up on the hull

This is after wetsanding 600 grid (to get the paint off), 800 grit (to get rid of the 600 grit scratches), and compound buffing with 3M Imperial Compounding and Finishing Material.

Still need to finish polish with something finer, but it came up pretty sharp!

Before and after - caught the kids in the reflection too ;-)

Very cool for sure. I used stainless bolts and locknuts to reaffix my deck. Pain but tight as a drum. Oh, if you hit something rivets pop, bolts don't so don't hit anything.

Pieces parts are at the powdercoating place - when I stripped the starboard side of the boat I found some fairly major gelcoat damage - decided to take it to a local pro to do that work - the gelcoat bubbled when i put the heat gun on it (i'm guessing water got behind it). Work should be finished next friday - they've been working on getting a good color match, turns out that's a bit touchy on the black and gray.

I have a huge list of things to do when I get the hull back - starting with mounting the NDT tower and installing the new stereo from Earmark, plus of course reinstaling all the hardware. Will post more pics when I get her back.

Some metal bits from the boat, back from a quick Aluminum Oxide blasting.
