flushing - sounds like a really good idea,right ?
in just about 20yrs,in this biz - i've never seen an engine failure,directly caused by an engine being raw water cooled.i've never seen a "clogged cooling jacket",never seen a block rusted through...
if the engine's filled with water - even sea water - there's an absense of air - no oxygen,right ?
the weak link on gas engines is the exhaust system - be it either stern drive,or inboard - these are the most common cause of an engine failure - some engine mfg's do not include the mainfolds in their fresh water cooling systems - some do - crusader,is a mfg that does...with all that,the risers,or,the manifolds are expelling sea water - meaning,these have a finite life.the normal accepted life is approx 5 years.flushing with fresh water will not prolong this - against popular belief...
it seems we're on this subject,so - i'm gonna run with this...
see next entry,for more info...
