Hi Henry,

I know some people have given up on the hydraulic pump but I have found it simple and reliable over many years. Until recently I used to top it up with Power Steering/ Automatic Gearbox fluid from any motoring accessory shop. It did leak a little for a long time gradually getting worse and through this Forum and Kim in particular I found the answer.

If you can unbolt and remove the pump and reservoir which on Azurian means undoing 3 bolts plus the hydraulic union it is possible to withdraw the piston - I had to knock to one side some retaining pins. On the end of the piston is a nylon washer something akin to the washer in a bicycle pump. On the advice of Kim I went to Ernest Doe near Maldon who took longer to find the right size in their various boxes than to pop it on. It hasn't leaked since.

Subsequently I went to my local branch of Pirtek for a replacement hose and it looked to me as if they had all the necessary bits and pieces - I think they do overhauls as well.. They have a whole range of hydraulic oils but I am not sure this is too critical. I know from experience if the reservoir drops too low you cannot raise the keel to line up the locking pin and there is no warning for the unprepared so for me it was a dash to the nearest petrol station on the first occasion.

One word of advice born of experience. Whatever you do keep a good hold of the pump operating tube. To get a full operational stroke I need to have the outboard not in the well. A couple of years ago in Burnham Yacht Harbour while making hurried preparations for a departure I thought to save a moment by hoisting the motor into the cockpit but not replacing the plug. Having made my adjustment with the pump I went forward to the saloon to deal with the pin having reasoned the handle was way longer than the well width and parallel so should be OK. Too late I heard a metallic ring behind me and turned in time to see a flash of stainless turning end over end in the air and neatly diving down the open well. They had no sort of temporary replacement at Burnham but fortunately we were able to lower to the lower raised position and insert the pin - then make a dash for HW at Havengore. Stainless isn't magnetic so that wasn't the answer otherwise believe me I would have tried. I now have a veritable collection of tubes but I think due to merication have found it impossible to achieve as good a fit onto the pump spigot as the original. I never now sail without a spare.
