Went over to shardlow marina for some red diesel and spotted this Dutch barge that has been replated - an enormous boat that must weigh 40 tonnes plus - glad I haven't got to black it!
Tightened the stern gland and installed locking nuts - found a couple in the bit box. Awkward to reach but worth it in the end. The port side nut was very loose - the opposite side to the formerly loose engine mount. Being a v bottom means that I am unable to empty the bilge completely - the bilge pump will not sit at the lowest point. I am reliant on the grease in the water to keep the rust at bay. It is full of diesel at the moment after the fuel filter change.
