The outside face of the Paddlewheel Assembly can be carefully
painted with antifouling to protect it, but it should be removed
if the boat is to be left standing in the water for long periods.
NOTE Replace the Paddlewheel Assembly with the bung when
returning the boat to the water to prevent the paddlewheel
impellor being damaged.
4.2.5 Withdrawing the Speed Transducer
When removing the Paddlewheel Assembly, a valve automati-
cally closes which reduces the flow of seawater through the
aperture, allowing time for the bung to be fitted.
NOTE Always have the bung to hand when withdrawing the Paddle-
wheel assembly.
Remove one of the “key ring” clips that lock the metal T-bar in
place on the top of the transducer, remove the T-bar and with-
draw the Paddlewheel assembly by pulling on the large ring on
the top (Fig 4.14) -
CAUTION Do not unscrew the large locking nut at the top of the Skin
Fitting when withdrawing the Paddlewheel assembly - this
locks the Sea Valve assembly in place.
Once the Paddlewheel assembly is clear, immediately replace it
with the bung supplied and lock it in with the T-bar - the Sea
Valve will slow the flow of seawater, but it should not be relied
upon to completely seal the hole.
