New to me 93 Ski Nautique

I don’t think I ever posted about this new boat since we couldn’t post pictures when I purchased it. Bought this 93 SN last September. I had been looking for a 93 in teal and this one came up on Facebook marketplace and happened to be in Durham, NC, which is approximately an hour from me, perfect. And to top it off I was driving to the beach the following day with my family and Durham is right on the way. Two owner boat, garage kept, all original (looks like a base model or some type of special order with the lack of grey/black secondary stripe and the purple pin as well as the all white interior) and the boat had 415 hours. Engine and bilge were clean as a whistle with a carbureted 351.

Haven’t done much to it so far, a couple of stickers were replaced. I also removed an aftermarket box that had been mounted on the dash and have a factory dash mount mirror to put back to original. My dash ground is bad and my gauges jump around and have issues when certain things are turned on. I plan to replace the wiring this winter, but in the meantime, what is the best way to add an additional ground to the dash? I was looking at a few old threads, but all the pics are gone. Would I just take a 10 gauge wire from the engine to the ground busbar to try to improve it for now? Any pics for this timeframe wiring would be appreciated!

Nice Addition to the Fleet. Just need a couple more decades to add and your collection will be complete! 

Beautiful boat you have there! Love the color of aquamarine or teal as some may call it.

Most likely a loose connection but I’m not familiar with your year.

Somebody will respond with what you’re looking for.

Welcome to the site!

Great looking boat, David!

Not the best Slalom tug but it'll do in a pinch but still beats my 88!  

Beautiful boat.  Love the NWZ "slant-backs".

The dash gel looked like that when I got it.  It just had this box mounted on the dash where the mirror would go (see pic #4 in first post).  After removal, that area needed some tlc.  Wet sanded to get rid of blemishes.  Finished with 1000 or 1200.  Compounded with Super Duty, Polished with Ultra Cutting Creme and waxed.  

You need another…I’m at the lake. Just saw this.

Also, put an acme 542 on the boat.

See below pic of dist plaque as well as red wire that was questioned.

Was thinking about this engine after I winterized it. I do have a second light Ken. I don’t know what it is for. I’ll find out this winter when I take the dash off to rewire. I have a reproduction of that plaque to go back to one light.

Also, curious, does a strainer operate properly upside down? I can move it back but it is easier to get to like this.



Winter to dos: new ground, re wire, replace passenger seat base, attempt to straighten driver seat (can you buy the slide mechanism still, mine is bent), fix the gas cap safety cable.

Dove in to a couple of fixes today. Removed the passenger seat. Need to replace the base. Looks like plywood. May go back with composite. Plywood still dry but wood is cracked so passenger seat sags.

Replacing a water hose between the therm housing and water pump that is worn through at the hose clamp.

Take a look at the back of my dash. Anything funky? The main issues: 2 warning lights. I don't recognize the boat safe box. Fuel gauge bounces around. Horn doesn’t work well. I want to add ground. Short of rewiring all to a ground bud bar, where to splice in a new ground? Wiring isn’t new to me but I don’t want to re wire if I don’t have to.

Could you post a pic from farther back showing the full pod when open like that? The 92 SN I picked up a few years ago is a rats nest with many mods.   I can only tip the pod up about four inches and reach under.   Seeing how it was once wired would help.   Mine runs, has PP, separate ground, but sometimes ends up low voltage.   

Any advice on how to rewire would be appreciated.

Just my thoughts on what is at best a daisy chained mess from the factory behind the dash -
