Rapid progress with removing the gelcoat and the first coat of epoxy resin was applied.
I started cleaning up the engine mounts which have become badly corroded. Firstly though, I removed the Yanmar water pump to change the impeller. This particular impeller has done sterling service. Fitted in September 2006 it has done some 800 hours and looked in perfect condition.
One downside of leaving the impeller this long is that it was very difficult to remove. Over two hours with WD40 and gentle levering. In future I'll try to take advantage of impeller longevity but remove and inspect at much shorter intervals.
Meantime I fitted an upgraded water pump Speedseal with run-dry option.
