25th Anniversary Limited Refurbish

I picked up the boat on Tuesday. There is a common theme in buying something used and that is "buy the best you can afford." I bought the only one available and it turned out to be in pretty good shape especially when one considers it is a 25 year old boat.

The most troubling concern was gel coat oxidation on the stern and starboard metal flake. There was a distinct line between what the tarp covered and what had been exposed to the elements, that was both visible to the eye and felt by the hand. The pictures don't do justice to how bad the oxidation actually was.

I set up an area on the transom and started to try various procedures to bring the gel back. I started with Meguiar's Oxidation Remover 49. It hardly touched it. I wasn't surprised but had hoped.

The next step was to wet sand with 2000 paper. It felt so much better but the exposed and unexposed gel still looked different. I then tried 1200 grit paper. It looked so much better but still left some ridges between the exposed and unexposed gel.

I removed the transom and starboard decals with a heat gun set on low and my fingernail. It worked will although a little tedious. I then worked on the transom. I went from 1200 to 2000 to 2500 grit paper. It looked OK when I was done but still left some significant ghosting. When it had dried it still showed the line between the exposed and unexposed areas.

I moved to the starboard side which had a very noticeable line. I worked it the same as the transom but still had a line. I went and purchased some 800 and 600 paper. I didn't expect to use the 600 but that is what it took to remove the line between the exposed and unexposed sections. The ridge between the decal and the rest of the gel coat is gone but the ghost of the decals remain if the light strikes it just right. I intend to replace the decals with the same so the ghosting should help with lining the decal up.

It was interesting the solid gel felt and looked fine with just the polish but the metal flake took a lot of work to get back.

I was very concerned about wet sanding as I had never done it before. I have a friend, who used to own an auto detail shop who provided me with guidance and encouragement as well as reading a few threads and watched youtube videos. It was still scary rubbing it down with various grits of paper and compound. Everybody said you will know when its working and amazingly you do. I am pleased with the results.

Looking good! Same thing on each side I take it?

It will come back to life. You may have just a small amount of color difference but if you get the decal almost spot on, only you will know where it is.

Thanks Brett The port side was pretty good so I just power compounded it and waxed. I expect that side was shaded. The transom and starboard side were quite oxidized. I am please with the way it looks. Yours provides a lot of inspiration.

I hope to get it wet this weekend and tune the rudder and make sure its running the way it should. If all good next up is Perfect Pass Stargazer.

I am also going to try with the 3 blade prop and then decide if I want a 4 blade instead. Any comments on 3 vs 4 blade would be welcome.

As for the dark car lurking in the background Mr. Bond drives its cousin. Mine is the Jag XKR-S coupe.

I prefer the mid range power of the 4 blade, I can live without that top 2-3 mph which I never get to anyway, that the 4 blade gives up.

Looks a lot better though, nice job. I'd definitely be a little nervious, too!

I went with a 3 blade OJ prop. I think Eastie did a comparo and the conclusion was that the 3 blade produced a slightly better ski wake over the 4 blade. I've been very happy with mine at 2500' elevation. Much snappier than at 6500' elevation. If you are at sea level, even better!

One upgrade I would recommend is the Transom Saver from Teakworld in Lebanon TN. $165, I used 8 SS screws to get it down.

That is a good suggestion. I had one on another boat. It looks like you installed it against the platform. I used the spacers to raise it up on my other boat.

Any other upgrades you have done that you recommend?
