No, that is a bad idea. Your truck alternator probably puts out something
around 50 amps max. If much of that gets applied to the pwc battery it will
be toast. I take all my small wet cell batteries out, clean them up, top
off the water and leave them on the corner of my garage workbench. Every
month or so I put a 1 amp charger on them for a day. Having them on the
corner of the workbench reminds me. Another option would be to mark your
calendar.

It is my understanding that a battery needs "exercised". Long periods
of non-usage (over the fall/winter/spring months) will result in the
battery loosing its charge and not be able to accept a charge.

With that said, is it possible that if I wired my battery (in
parallel) to my Ford truck battery, will it be "exercised" and be
ready for another full year of boating, or will it damage the PWC
battery?

I'm trying to avoid the cost of trading in the old battery and
purchasing a new battery each summer.

Thanks in advanced,

How? The power produced by the alternator is regulated. The only way
you'll see that 50A current is if both batteries are dead flat. Then,
the truck's battery will be taking half of that.
