On different subject, does anyone have any expierience with installing an aftermarkt fuel tank? Can't find an original in the EU, so will probably go for a polyethylene tank because they relatively cheap.

My take on this: after having gone through the whole process of sanding (different grits), buffing and polishing mine, only to have the red go dull again after two summers, I decided to have the red stripe on mine stickered. Zeven years later, it is still shiny red as it should be. And, at five yards away, you can't see if it's gelcoat or a sticker.
Contact Jo. We have a tank from a later model SN laying around. Take measurements to see if it could fit... Maybe you can arrange a deal with Jo. I'll let him know later today. |

If that fits, that would be amazing. I'm sending him a message right now!

Small Update: Progress has slowed down a bit over the past weeks as we're trying to figure out how to proceed. I've been reading up on a dash rewire, but as I've never seen the dash and wire loom as it was installed it gets a bit confusing. I'm a bit lost if I should up the wire size for all wires in the instrument cluster or only the ones leading from the battery to the daisy chain. reading a lot about adding extra power and negative wire to the wire loom, just not really sure where to? Anyways, I'm guessing that a lot of things will become clearer when we start working on it. Not sure what happend to the shaft strut, but the 2 bearing set screws were missing the heads. I drilled a small hole in one and tried removing it with a screw remover, which broke off inside of the screw so I had to drill them out completely to remove the shaft bearing. Bearing needed a lot of convincing to be removed so I used a hand saw to almost cut through the bearing from the inside. With some gentle force everything came out.    The paint on the throttle lever body was quite crusty, so I stripped the old paint, put some coats of primer on it and some coats of black paint.   Also, this morning i received some fresh parts for the engine    |

Kristof, Thanks for the insight on the sticker, we'll probably go that way as well.  The fuel tank turned out to be to large, so i'm looking for a suitable replacement.

I'm assuming you pulled the instrument cluster out of the dash. Put up a picture of the back of your instrument cluster. I rebuilt my 86 nautique cluster wiring and i've got pictures. If it looks the same, I can send you what mine looked like finished and some info on how I went about it.

Hi Andrew,
Many thanks in advance. As far as I know, the dash wiring should (mostly) be the same between the SN & the BFN. We bought the boat already disassembled , which is what makes some parts a bit more complicated. herewith the view of the dash/cluster (VDO gauges) as it is:

I just rewired my dash in my 93SN. If you haven't seen the thread, take a look. I tried to put some good pics in there. It is current;y on page two and is called, newtome93SkiNautique. Good luck.

Wow, that's in pieces. Front of your dash looks like mine, so they should be pretty close or the same.
First picture is the back of the dash before I rewired it. Note there are some repaired wires on the before picture, done when I was replacing the RPM gauge, anything I repaired has marine grade heat shrink terminal connectors. Most of the old connectors are dark blue.
Second picture is after it's rewired. The coiled up wires next to the two terminal blocks will connect to the old power wires under the bow. I added watertight terminals that I can disconnect to the ends so I can pull the dash without cutting anything if I need to pull it again. I have to stick my head up under the bow and check where I landed them but I think I ran an additional ground from the engine and a power wire from the solenoid to the dash because the wires supplying power and ground that are part of the old system are too small gauge wise. Good ratchet crimpers are a must for doing this neatly, just FYI. I can get some pictures of the back of the rewired dash installed if needed. Boat is currently under my back deck at the tail end of stringer replacement. Let me know.   |

Resolution looks better on my computer than it is after I uploaded the pictures. PM me and I can email you the pictures, might be able to follow the wiring better.

Since I don't see any mention of dash wiring diagrams, I thought I'd mention that there's a wiring diagram listed as an 86 in the CCF Reference section under manuals. It was drawn in August 84 so it would be for an 85 you'd think, and carry over to 86. There are 2 versions shown one for VDO gauges like yours and another for Teleflex gauges It'll help you keep it "color correct" with the wiring

Lenny,
What KENO said. The wiring diagrams in the Reference Section helped me solve some problems on my dash. For good measure here's the link: '86 Wiring diagram |

Didn't know there were different wiring for the VDO vs Teleflex. My gauges are VDO.

The only real difference is the terminal connection locations on the back of the gauges and wiring hookup to the gauges.
VDO had spade type connectors Teleflex had studs with nuts

Thank you all for your input. We started the rewire and in the end it isn't as intimidating as it seemed. We just needed a little nudge to start and i'm guessing we'll be done by the end of this week. I'll double check our work with Andrews picture to make sure we dind't make any mistakes. |
