[Healeys] Coolant change

[David Porter]

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
