Saildrive Seal

Volvo recommends that the saildrive seal is replaced every 7 years so we set about having this work done before Molia is put back into the water this season.

We will combine this work with servicing the engine and replacing the split anode that sits between the saildrive and the propeller.

The service will replace the oil and the filters.

The saildrive and the lower seal have been removed. In fact the engine is also in the Engineer’s workshop – so you can see right through the engine compartment !

Unfortunately the Engineer broke the propeller hub when he was taking the saildrive off. So we will need to get a new one. See New Propeller.

Antifouling

Molia has black antifouling paint which needs renewal before we launch. But which one to choose?

In 2016 Practical Boat Owner (PBO) tested 20 different paints in 13 UK locations. The results are online here. They did not actually test in the Bristol Channel – so I chose a paint that did well in South Wales.

I will let you know how it performs in the waters between Dartmouth and Portishead!

Application

The hull was pressure-washed when Molia was lifted out of the water, and the existing surface is clear of any growth and the condition of the surface is good.

Wet and dry sandpaper (I used a 180 grit) all over, then masking off the waterline. Well stirred paint. Application with a small roller takes just over one hour per side on Molia, and almost all of a 2.5 litre can.

My favourite bit (centre) is painting the keel and its bulb.
