For the record
The new shaft and prop are fitted and look great. I got the new shaft manufactured locally in 2205, for $500 (which is pretty cheap
for down here). I did most of the installation
myself, with some assistance from a prefessional shirpwright / marine engineer
($100). We replaced the glad packing while we were at it and tied up the stern gland and shaft flange at the gearbox
(all included in the $500).
The new prop amazing compared to the old one. Our motoring performance is night and day, especially into a headwind or against chop. Significantly less vibration too. And no noticeable reduction in sailing performance either.
All in all we are, thus far, extremely happy with the new gear
. Obviously it wasn't a cheap
exercise, but on balance, money
well spent. I did consider upgrading to a dripless gland, but the budget
wouldn't stretch. Other than that, very happy.
