Hi Dwight:
I have enough 'fun' with the boat since hauled....I don't need another
one if not really necessary.....I have cleaned the bottom down to the
barrier coat...when the boat was hauled some the paint was flaked and
lifted, so I started wet sanding with 40 grit aluminum oxide sandpaper,
then I pulled out a putty knife, then a scrapper and finally a tungsten
carbide scrapper.
I swore I would never do a bottom and here I did mine the past few
weeks. I painted my bottom last Fall, first time I had done
that....don't think the old paint was dry enough to accept the new
paint....not sure but I didn't like what came out of the water this
Fall. Other than under the pads, the bottom is stripped and now sanded
smooth.

I would say in your case robert not very often. Check the freezing
point around here if its -20c or below good to go. Only other thing is
depletion of corosion inhibitors i would also say your antifreeze is
good on that. I use Prestone conc and dilute to 50/50 with distilled
water. I had to replace my heat exchanger and my fresh water pump so i
used a fresh mix to fill then. I have never changed coolant in any
vehicles i owned. Very seldom did our lab see a need to change this in
naval systems either. But it’s cheap so if you want some fun go for it
