Couple of questions.....
impeller -- Is there a rule
of thumb for when to change it? So many hours, years? I assume it is best to replace before it breaks.
I've had my boat now for about 1.5 years now and when I bought it I noticed that the coolant
was in fact water
(What appeared to be water
could be additives not sure). Well I forgot about my water coolant
until just recently and now we are getting ready to go on a bigger trip that will require motoring more than usual.
I am tempted to leave the thing as is because it runs perfect but I know I should probably flush and replace.

Is there such a thing as using water with additives as opposed to coolant for whatever reason?
Makes me wonder why the PO did that
Any tips you can pass on or a fluid recommendation would be great!!
