I am wondering if anybody has the propeller shaft specifications, more specifically the shaft length, for the ocean 43 powered by Yanmars. I checked the owners manual, and it mentions the specs for the volvo powered boats, which had 1 3/4 " shafts. However I have 2 " diameter shafts, so Im not sure if the shaft length is different with the yanmars compared to the volvos. I had a similar experience to Pascal, on Saturday, excpet mine was in 2000 ft of water, so no chance of finding the prop. Was running down the coast of Grenada at about 22 knots in calm seas, and then heard a bang and experienced a loss of power on the starboard engine. I then took a dive and found this.(pic attached). There is some damage to the hull near the rudder palm, which I assume is where the prop hit the hull, and the cause of the bang.
