mbird Posted March 13, 2010 Share Posted March 13, 2010 Hi All Following out lift yesterdat at Brundall, which was only intended to be a weekend in the slings so I could fit a new depth transducer, we found we had some significant damage to all four props. This means we will now be out of the water for a fortnight, and dropping back in the weekend before Easter. I got the transducer fitted no problem today, and then Col (HJII) very kindly agreed to come over and help me changing the oil in the outdrives, to show me how it's done. We weren't going to bother, but it was only when Ian (Senator) suggested it's be a good idea, it got me thinking a bit, even though I though the oil was done in July. Upon draining the starboard leg, the oild was black, and had obviously not been changed for some time. There wasn't any emulsification to speak of, so at least that was good news. On draining the port leg, the oil was almost new! As both drives had been off in July and had new bellows fitted (which still look new), why on earth would they only change the oil in one leg???? It also turned out all the anodes are zinc, and completely covered in oxidation and scale, rendering them useless. The ring anodes were also not doing much as the surface of the leg behind was painted! I have now ordered two sets of aluminium anodes from Aquafax, which I'll be fitting next week after I have rubbed down the mating surfaces to bare metal. On the plus side, the legs do seem to be in good shape, so I'll just be giving them a quick wire-brush and a coat of the Volvo grey paint. The antifoul on the hull is also pretty good, as this was done last summer, but while it's out I'll give it another once over. I can also report the oxalic acid and wallpaper paste certainly does the trick with the black streaks and genral grubiness! I didn't go for the woodchip finish as Jimbo suggested, but I'll take a photo of the nice floral print I went for instead My thanks to Col for giving up his time to help us, and now I've seen how it's done, next time I'll be fine. It does just go to show, though, that you should never assume that you are being told the truth about work that has been carried out!
