To me, the real downside of an I/O is the drive and the drive's big

We have a lot of I/Os in our area of SW Florida, including about 80%
of my neighbors. Interestingly enough you don't hear about many boot
problems although one neighbor did succeed in ripping the I/O clean
off the transom creating a boot failure of sorts. :-)

Cooling issues, manifolds and risers are near the top of the list
based on what I've observed.


I was going to say,t hat if I had an I/O on salt, I'd want an enclosed
cooling system, but still pull the boat after every use, and flush the
lower end with fresh water.



I googled marine cooling and this is one of my responses:

Some good info on cooling systems he

I wish I'd known about the fresh water systems when I bought the boat. I
don't know why they aren't the standard, although they may be the standard
now. I wonder how much more difficult changing the oil filter becomes with
all that extra piping and the exchanger mounted over the engine?
