thanks Steve, we have done an upgrade with an electric winch and some batteries, the issue now is the winch overheats and it takes a long time for the keel to lift fully, say 15-20 minutes by the time you wait for the winch to cool down. trying to understand why, oil does appear at the top of the keel, so am guessing a seal needs replacing .... think i just need to find someone that knows there stuff ! it isnt me
