Does SS make a noticable difference Paul? Just wondering about my two DP's??
I had heard that Ali bends if dinked and therefore acts as a "gearbox saver" and that SS is that much harder and therefore riskier on the shafts, bearings and gears. All that said, there ain't many rocks around Porthmadog...just sand...mountains of sand.
S/S sure last alot longer Dave. The legs have a "shear collar" between the middle and lower units that are designed to break rather like a shear pin on an outboard to protect the gearbox. I found a set of ally props do around 3 seasons before they wear thin and burn at the base of the blades. The S/S ones cost around double but there is no wear to speak of and they clean up nice and shiny. The down side is that I eat anodes for England. On the "after" pic you will see I have fitted anodes to the top of the cavitation plate. This helps alot and makes the ring anodes last just about a season.
Those with long memories on this forum may have some reply on rocks / Porthmadog / Pwllheli. I'm expecting it... /forums/images/graemlins/smile.gif
