I would take it some place or fix it myself. If there is a leek how do I fix it . is there an expantion diofram in it Any thing else I should know. Thanks Steve

I had that issue with a bulkhead mounted compass. It had a rubber diaphragm with a leaky seal on one edge. I refilled the compass with mineral oil and resealed it. The seal leaks finally reappeared a few months later in a nice oily mess and I replaced the compass.

If it is a good compass and worth repairing, send it off to Island Compass. He does great work and is very reasonable. Otherwise, just get a new one.

If it happens to be a Ritchie compass, contact the factory about sending it in for refurbishment. I did that with a compass on a Grady White I used to own. It had developed a bubble. Ritchie did a first class job and didn't charge much at all.

I have an expensive (came with the boat) Weems & Plath which developed a bubble and the yard sent it off to be refilled and resealed several years ago.Now it's fine. It's not something you can do yourself and you need to freeze it, I am told when you do it. I've seen a tiny bubble appear at times when it is very cold in winter and it disappears when the compass warms up.

If the compass is 30 years old. it may be best to replace it. At that age the acrylic lens may start crazing and leak there also. Depending on the model, they're not that expensive.

I developed a bubble about ten years ago. Bought some compass fluid and refilled it myself. Only this year have I developed a new bubble and will refill it again. The bottle I bought cost $12 and will be good for several more refills.
