Well it has been quite a while since I posted on here about my '89 SN 2001.
So what have I been up to lately...?

First of all I did some stringer repair. Yes, repair versus complete stringer job. Tim Benjamin advised me last year not to do this one month before beginning of the season, but I totally ignored his advise LOL
So last march, as I got the boat out of winter storage, I wanted to investigate the weak floor between the co-pilot seat and the skipole.
After research and calls, I knew it had to do with the wood planks in this part of the floor. I thought to myself: "what the heck, lets check this out, even if it is one month before the season, ignoring TRBenj's advise" Embarrassed
So my buddy and I took the plunge saw and very VERY carefully cut into the layer of fiberglass to investigate. As we peeled off the section of fiberglass, we did indeed find the rotten planks beneath it.



Call me the lucky idiot, but beneath this, I found bone dry foam and the stringers only affected for the top 1 cm (less than half an inch) on the length of that rotten plank. Stringers were still rock solid. And yes I did investigate all the way through the whole boat with the very scientific Tim Morfoot tapping method (great YouTube video BTW Foot  Big smile ). Even the bluckhead was still solid (minor damage on top made by the plunge saw). Oh FYI, I do not have one single soft spot anywhere on the floor...

So I spent the next few days soaking the stringers with very thin epoxy (CPES?) and fixing that top 1cm on the small part affected.
I know, redneck repair. Yes, I am a redneck that way. I always avoid extending repairs more than needed ("If it ain't broken, leave it as is" is my creed). It is how I maintained my BMW for the past 15 years and it is still running like a champ with 475.000 KM (295.000 miles) on the clock.
I did spend quite some time researching about products and materials for this. Called and visited specialist companies over here for it.

Next I poured some epoxy foam. This stuff I got from one of those specialist companies is awesome. When cured, this foam is hard as concrete, yet weighs next to nothing. Even hit some spots with a rubber hammer (hard!). No dent whatsoever. 
After that cutting away bulk excess with a multitool and sanding untill it was a nice and even surface.



Poured expoxy over the whole area to seal everything. Then three layers of fiberglass mat and epoxy.
After that cutting some marine plywood to size.



Then I covered this ply with three layers of fiberglass mat



Mixed some thickened epoxy and "glued" the board in place, making sure the epoxy oozed out everywhere to make sure the whole thing is sealed. Next sanding and flattening everything out.



Next, glued the carpet back in place and fitted the interior back in.



I know it is just a repair, but I am convinced she will hold with no issues for the coming decades... She sure feels rock solid again.

Mid season, while driving the boat to my waterski club, she died on me. Had to be towed back to the marina and trailered her home to investigate. We found out the ditributor was the culprit. Shaft broke clean in half. Checked in the engine if there were problems with the cogs, but all was fine. Ordered a new electronic distributor and she ran fine again for the rest of the season.



The past few weeks, I repaired and refurbished the tower speaker box I made back in 2013. 
My favourite part about this was the sanding and fairing and sanding again and fairing again and... NOT!
But it looks the part again. Ready for next season.

The biggest change though, will be a whole new interior, scheduled in Februari with my upholstery guy.
He is a friend of mine and my boat was the first one he ever did back then. 
I made quite some publicity for him at our marina and sent him a lot of cutomers over the years, so he proposed to redo my whole interior for free as a form of payback!
I am going custom on it. Because I never really liked the original interior. 
It is gonna have a more modern touch to it...
It is gonna surprise some of you I bet Cool

Correct.
And correct it's just an automotive one. Did add a gasket between the cover and baseplate to have it more 'waterproof'...

Waterproofing should be about the least of your concerns with the distributor.

Spark and gas vapor meeting up with each other inside the distributor and the resulting explosion that follows is the concern.

There's a path for the gas vapors where the rod from the vacuum advance canister enters the distributor housing so if there are gas vapors in the air and they meet that spark in the distributor, it makes for a bad day.

If you compare yours to a marine HEI unit, like a DUI for example, there's a blockoff insert where the vacuum advance has been removed, taking away that path.

The DUI also has 2 vent holes in the bottom that are covered with brass screens.

You might think since vapor can get in through the screens, you'll get the same big explosion, but the screens contain and dissipate the explosion inside the distributor so that the gas vapor in the engine compartment doesn't ignite and explode.

Typically there are 2 or 3 layers of screen in each hole on marine distributors with vent holes.

Some people put in automotive units and haven't had an issue as long as there isn't an explosive atmosphere from a fuel leak in the engine compartment.

I'd rather have a marine unit to minimize my chances of an explosion that could kill or badly burn me or anybody else in the boat at the time.

Some marine distributors have no openings at all and are USCG approved or meet USCG specs.

Lots to think about, some people take the chance, some would rather not. Wink

Thanks for the input Keno.
So, I could seal that path at the vacuum advance, could I not?
Will look into that when I get the boat out next march.

BTW, there are guys over here that did not hook up the vacuum advance canister and run fine. Most of us here run our V8 ski boats on LPG instead of gas FYI...
So if I remove my vaccum hose and the rod from the canister does not move anymore, I could seal that opening? 
Just thinking out loud here...

I recently sealed off the openings around my distributor's vacuum advance rod with epoxy, plugged the vacuum advance canister, drilled a hole in the bottom of the distributor body and epoxied a bit of stainless steel mesh in place over the hole in an effort to make my automotive setup somewhat safer. Definitely want to get a proper marine DUI soon though.

LPG can make for a pretty good explosion too Wink

It'll run fine with no vacuum advance, it's just the explosion odds/chances of the non marine unit and that's a personal choice.
