[Alberg30] Fresh Water Cooling

[Miabarchet at aol.com]

I currently sail in fresh water (Lake Ontario) but plan to relocate to 
Oriental NC next year. I am wondering about the need to protect my Atomic 4 
from corrosion when a sailing in salt or brackish water. I know Indigo sells 
a fresh water cooling system. Are they necessary? Is flushing the engine with 
fresh water adequate or advisable?

I recently saw a Groco Engine Flush Kit at Boat US (pg.467, 2001 Catalog).  
It screws into a seacock and Tees off with a quick release plug. The plug is 
removed and replaced with an adapter with a female garden hose fitting. The 
weak link seems to be the quick release plug. It seals with 2 O-ring on 
grooved in the outside diameter of the plug.

I've considered making my own but would need a bronze nipple (from seacock to 
Tee) and a bronze valve neither of witch exist.
