Re: C-Drive vs Linecutter

Hi Dean,

Slightly off topic, where are you hauled out in Scotland? Masts down? It will be pretty windy in that part of the world over the winter months.

Hi folks,
We are on the hard stand and I started the job of replacing the C-Drive lower seals since my C-Drive oil has gone a little like a chocolate milkshake.
When we came ashore, I noticed a trickle of oil down the keel which implied the lower seals were leaking oil.
This afternoon I removed the autoprop and the Spurs linecutter which I installed last year to get at the V-bolt in order to drain the oil.  After removing these it became clear that the source of the leakage is the V-bolt, and not the C-Drive shaft seals, which do not show any form of leakage.

The rubber O-seal on the V bolt appears to have perished and allowed water in and oil out of the C-Drive. I’m fairly sure the O-seal was provided by Amel when I ordered the V bolt last year. The V bolt itself was rather loose today, and I needed to rotate it an additional 35-45degrees clockwise in order to be fully tight.  In this position, the V-bolt does not align with the line-cutter, so that is a problem.

The solution would appear to be to fit a new seal under the V-bolt. However, it’s a concern that the previous O-seal perished in 6 months in the water.

Have others found this problem, and is there a better solution than simply replacing the seal?

I have a general philosophy of not fixing stuff that’s not broken, so I’m now considering leaving the shaft seals (lip seals) intact. The oil was perfect before I installed the line cutter in April, and close inspection shows no visible leakage from the shaft seals.

Thought ?
