hi bill bach and sdteve wallace,
read your mail on repowering, shaft seals, and
propeller sizing. have a couple of suggestions,
a- for the prop. contact a reputable propeller shop
giving them the boat weight, length at waterline, and
all the info on the engine, horsepower, and all the
performance curves, (rpm - horsepower ranges etc.) the
prop. shop can fix you up so that you only have to do
the job once.on the shaft seal, I used the standard packing type
with flax packing. the teflon packing will cut into
your shaft over time. now the sneaky part, the seals
come in 2 types, one for 12 kts. and less, the other
is for 12kts. and more. the 12kts. plus has a water
injection port aft of the packing. an ordinary grease
fitting will screw in the hole and 20 or so pumps of
grease will give you a dripless shaft seal at any
speed for any lenght of time. another good thing about
this install is that the shaft packing nut only need
be hand tight.
if anyone has any questions about installs, etc let me
know, will be glad to share what i have learned.
