Further to my recent post and the very helpful advice I recieved, I thought I would give you a wee bit of an update.
The issue was I could barely make 5.5 - 6 knts no matter how high th engine reved and it would rev freely. 43' Oceanis.
Did a lot of investigation, spoke to previous owner, supplier of Prop (Max Prop), consulted Max prop liretaure etc.
Discovered that previous owner had "adjusted" tinkered about with the pitch when he fitted it. General concensus seemed to think that pitch/blade angle should be in the region of 22 - 24 deg.
So boat up now and prop off this morning. Low and behold, set at 18 deg.
Going to adjust to 22 deg, change cutlass bearing, antifoul and back in early next week. Hoping for a couple more kts at 2,400 revs. Fingers crossed....
Should make a big diffence when having to motor on a typical 90-100 mile passage. 12hrs instead of 16hrs
