, boat now goes completely straight under power without and hand on the wheel.
I did 2 things and I am not sure which one has worked as hauling the boat out several times is too expensive however:
1st I ordered a new type of propeller
from Axiom Propellers Ltd :: home
and the director advised a 24" left handed (as before) and offered a money
back guarantee it would solve the issue. Can't get much better than that.) It seemed very low cost and as he may have thought solving my problem was worth a low price
as his main market for these is narrow boat, presently.) I am keeping this to myself as reporting teh success as the unwritten side of my deal with him.
2nd, when the boat was hauled a local marine engineer
, Mike West from West Marine
Brighton, noticed that the prop was 7 inches from the back edge of the P bracket (ie: far too far away) and the cutlass bearing was shot, presumably from the vibration, although this was not noticeable before.
There was an alternator
fitted to the shaft with a sort of universal joint as the engine
is not totally aligned with shaft tube. It looked like the alternator
may have been an after thought and when the boat was built the builder
possibly mounted every thing, saw teh problem and thought fxxkit, I'll just leave this like this and hoe no one notices.
Anyway, the original prop top blade was only 5 inches from the top of the semi balanced rudder
and was the flow was pushing the rudder
over under power.
Mick West's engineer
managed to grind off 4.5 inches of shaft inside the boat without dropping the rudder and re attach the shaft alternator et al..
And bugger me, today, I motored round the marina and it completely worked.....Phew!!!
to be honest, or dishonest more like it, if it had not worked I was going to sell the boat...as it was so annoying the pull to starboard I would have constantly hated it..
