Well....
i ended up taking on this task on the weekend just gone, I picked up a blister pack of bearings from my local chain store as it was the only option on a saturday afternoon when i had already pulled two hubs apart.
Disassembly was simple enough save for a few frozen bolts that mount the brake calipers. Then came the biggest headache in the world. Removal of the cones, which ended up being impossible... the drift didn't budge it... a screwdriver did even less... i guess they have been in there since 2002 and simply refuse to come out...they were very very smooth, no lip or scratches.. even the old bearings were perfect... but they were out and on the ground so they were going in the bin, the previous owner probably used the boat a dozen times in its life and lived 1km from the ramp, he also claims to have never submerged the trailer either, so that explains the condition of the bearings.
So, i packed the bearings with grease, and re assembled using the old cones and filled the hubs with grease... i suggest that i will need to get hold of some SKF or NSK quality bearings and get a mechanic to press out the old cones because there is no way in hell i am getting them out.
