After 20+ years of service, the compass on Talia (SM#209) has developed an air bubble (astonishing service life by today's standards). The compass is a Plastimo Olympic 135.
My intention was to remove the compass, replace the oil, and/or diaphragm. However, after disassembly followed by a little web research it appears this model compass is not serviceable.
Anyone on the forum serviced or replaced this compass? Replaced with the same Olympic 135, or other make/model?
Many thanks for your input.

Hello,
Same happened on my previous boat few years ago. I just replaced it with new one. Cost was close to 200 Euro. It was easy, 1 hour work. The old one I kept for emergency.

We were able to service ours. (A YouTube exists for this) Easy. Remove the top cover. (The plastic buttons on the side act as the hinge for the cover and carefully snap out. If you lose one, Plastimo supplies these as spares, sometimes for free.) Remove the compass from its mount. You don’t have to remove completely, just to tilt it forward a bit. Prop it so it stays upright. Light wiring didn’t need disconnecting. The dome is plastic. Drill a small hole at the top, still under where the cover is located. Make sure the hole is at the top center of the bubble (the reason for tilting the compass forward, to position the top of the bubble under the cover location). We carefully used a home made funnel to fill the air bubble with mineral oil. When full, clean the outside of the sphere very well. We used clear 5 minute epoxy, a small dab, to cover the hole. Let it set up a bit, so it’s quite thick (so it doesn’t run into the hole). Let dry and reassemble. Bubble gone! We sold the boat two years later. We keep up with the new owner and the bubble has not reappeared, another two years later. ~~~⛵️~~~Matt

Hi Matt & Michelle,
I replaced ours
four years ago in Martinique because of a large bubble. I wrote to Plastimo
and asked them if more compass oil could be added. They responded by saying
this model is a sealed design and if I have air, it is because there is a small
leak somewhere. It turned out to be a good idea to replace it since the housing
had become very brittle and easily cracked when removing it as you can see in
the picture. I purchase the replacement at one of the local ship stores in La
Marin. https://www.creampuff.us/2018/02/martinique-and-repairs/
The exact
replacement is Plastimo Olympic 135 and is available worldwide.
https://www.plastimo.com/en/compas-olympic-6274.html
It is worth
noting there are screws securing the compass under the plastic plates on the
compass. Four screws. Also, the new compass is LED and you cannot dim it. It is
on or off. The LED is 12/24v. I had spare incandescent bulbs for the compass and
I could have used these to keep the dimming function however, I opted to stick
with the LED. Use silicone to waterproof the assembly.
The compass comes with calibration instructions. Ours was only
off by 1° out of the box.
With best
regards,
Mark

In the US, mineral oil is sold in most hardware stores. We found it in La Rochelle France in a kitchen supply store. It is a thin, clear, inert oil. We also used it to fill the void in our through-the-hull depth sounder transducer, so we did not need to drill a hole in the hull for our depth sounder. We also use it to season our cutting board.
