RE: New trawler owner...Some questions.

Congrates on your purchase!!

We recently replaced a 1 1/2" ball valve in a 34' Mainship for the same reason. The exercise took place at dockside. We removed the hoses, clamps and gathered two pipe wrenches, one mid size, one very big and a large cheater bar to assist. Once the old valve was loosened enough to not require a wrench a couple of shop towels were made ready to plug in the thru-hull once the valve was removed. Teflon tape was applied to the thru-hull male threaded connection, the shop towels were removed and the new valve was screwed on. Once the new valve was tightened and orientated for proper valve handle clearance then the hoses and clamps were re-installed. What water came in during the process was taken away by the bilge pump, no issues there. Caution should be used when removing the old valve so as not to disturb the backing plate, other wise pretty straight forward.

Your operating temperature may be higher once the season changes. As for the 1750 rpm's look for the sweet spot, where she just hums along. If you think that 1750 is to slow, then once an hour or so open her up. This should help clean the oil from the cylinder wall and prevent glazing. Your 1.4 gph may change once you get her loaded with, fuel, water & beer.

I have been told that once you begin to use a bow thruster, you begin to forget how to maneuver.

Good Luck,
