Richard,
not to sound argumentative, but the seawater systems/heat exchangers
or what ever name are vastly different systems, but the engines are
still subject to the same conditions as our cars and preventative
maintenance should be a higher priority in off shore capable boats.
Those boats using fresh water systems are highly prone to coolant system
issues too. Mostly due to different temps across the heads, but also
lack of pump lubrication... IMHO
