Speedometers - 1985 Stars and Stripes

Hi Everyone!
I am new here, so hello.

I am refurbing a 1985 Mastercraft Stars & Stripes.
The spedometers do not work.

Does anyone know where to get replacements that can work with the dashboard?

Any help or direction greatly appreciated!

-Paul

What is broken? Several things to consider, some can be fixed, some cannot. Most can be fixed....

If you get new ones, I'd be interested in the broken ones. Most can be fixed. Thanks...

Hi-
What would you recommend as first step to fix?
Are they connected to fuses?
I do not know much about those...but do you know the steps to fix?

If I do choose to replace I can give you the old ones...

Hi Waterlogged-
I have not taken a close look yet...the gauges do not move at all.

What would be the first steps to fix?
Any guidance appreciated...

If I do decide to replace I can give you the old ones.

Thanks for the offer. I'll take them if available.

Several things to consider on the 85;

Start at the transom: a grey looking pitot pickup tube attached to the boat.

Pitot tube can be plugged up at the inlet with debris...take a paper clip or small drill bit (by hand) and run up in there and see if there is any blockage.

Next is the tubing that should be connected to the top of the pitot tube.

That leads to an equalizer unit (one for each) on the inside of the boat somewhere near the fuel cell. Frozen and burst / cracked thus no pressure. Or those may be OK as well.

On up the line; (aside from cracked or deteriorated tubing) the tube should be connected to the back of the speedometer (typically where you may feel water coming in on your legs, if disconnected).

So now.... that should give you "connectivity" if all is good to that point. The needle(s) should move.

So if that is not the issue(s), then comes the internals.... only one significant place to first look.....after careful disassembly (did I mention careful?) there is a metal diaphragm inside that fluctuates the needle from pressure. Often (not literally but at this point) that diaphragm can separate at the pressed seam, thus not holding pressure. These can be fixed with patience and soldering skills if not too bad off. I have seen some that were ruptured or not carefully handled and were trashed beyond repair.

Unless something or some part is broken to the extent of irreparable damage, most of these things can be fixed. You'll also need to source new machine screws to reassemble, typically #4 x 40 tpi machine screw (very fine thread pattern), length to suit (two different lengths for two different applications).

That said and prior to reassembly, you can sand off the face of the dial and make it really smooth (did I mention really smooth?) and apply a decal that is identical to the face plate. Paint the needle, put in new glass (or use existing glass to keep from having to drill new holes),m add new hole grommets (hardware store item) and apply the face plate sticker. They will look brand new.

Takes some time and patience but that is the gist of the system for repair. Me???? I like the challenge of fixing something.. Others like plug and play replacement....Your call.

PerfectPass makes a nice GPS unit that will work as well. They are proud of it ($$) but it is a good GPS system. I use their GPS speed control system and really like it.

Here is a set of speedometers I repaired and rebuilt a few months ago....

Your mileage may vary.

I just went through the entire system to learn it was merely a kinked line where it entered the hull. Don't overlook the simple things.
