duct ion gears tbat are also water

water enter at tbis point and be
piped from tbere to tbe engine.
Installation of the water scoop is
a simple process. A 3" square by
3/4" thick block" is fastened to tbe
inside of tbe bottom of tbe bull
witb four wood screws and set in
bedding compound. A bole is then
drilled tbrougb the block and bull
the same diameter as the outside
di~cnsion of tbe water scoop pipe.
The scoop pipe is then inserted in
tbe h~le from tbe bottom of tbe
bull and fastened in place. A seal-
ing compound is placed around the
pipe on the inside and tbe locknut
tightened.

Host often engines are installed
witb water piping that simply dravls
water to tbe pump directly from the
sea, circulates it through the en-
gine and discbarges it all over-
board. In tbis type of system, en-
gine temperature is determined by
the temperature of the incoming
water, pump capacity and the degree
