Mercury engine. I’ve never had a jet boat
before, and the book I got with it doesn’t
say a thing about how to winterize it. I’m in
Arizona but will be hauling it to Michigan
this season. I looked online but only found
how to flush it out. Ron Grinnell
JOHN ADEY: According to Mercury literature, the 240 jet has a “self-draining cooling
system” that eliminates the need for adding
antifreeze. Other winterization procedures are
mentioned on the Mercury website, including
fuel and oil information. But from a freezing
standpoint, it looks like Mercury has you covered with the self-draining design.
What windlass is appropriate for 60-pound
Manson Supreme anchor? I have a Cruisers
3750 aft cabin, so I need a low-profile,
gypsy-only (no drum) windlass. What maxi-
mum pull and working load should I be
looking for? John McCurry
DON CASEY: The rule I follow is that a
BRONZE OR MARELON?
windlass should have a pull capacity of not
less than three times the total weight of the
ground tackle you want it to retrieve. Your
anchor weighs 60 pounds. Perhaps you have
it mated to 150 feet of 3/8-inch high-test
chain. This size of chain weighs about 1. 5
pounds per foot (weight charts are avail-
able online and in many catalogs) for a total
chain weight of 225 pounds. That means
this combination requires a pulling capac-
ity of not less than three times 285 pounds
(225 + 60). I’d make a pull capacity of 855
pounds my minimum. Against the possibility
of deciding to increase the size of the chain
or the weight of the anchor in the future, or
simply for the assurance of extra capacity if
needed, it can be a prudent move to raise the
minimum pulling capacity to four times the
tackle weight. When it comes to anchoring
gear, it’s hard to be too conservative.
I have a 30-year-old fiberglass sailboat that I
use on San Francisco Bay and for coastal sailing. I’m considering using Marelon fittings
to replace most if not all my thru-hulls and
seacocks and would like your opinion.
DON CASEY: Bronze is a wonderful
marine metal and I prefer bronze for lots
of boat parts over other choices. However,
bronze thru-hulls are always a risk for corrosion, and every bronze seacock I ever
had eventually wept or out and out leaked.
I switched over to all Marelon on my own
30-foot sailboat more than 20 years ago.
Those same seacocks are as easy to operate
and as leak-free today as they were when
first installed. The only maintenance they get
is regular exercise and a bit of Teflon grease
applied to the balls with the end of a wooden
dowel whenever the boat is out of the water
for bottom paint. I’d never go back.
BARRIER BOTTOM LINE
I have a 25-year-old boat that’s never been
bottom painted. I’d like to keep it in the
water this season, and the bottom will have
to be painted. Do I have to apply a barrier
coat first? Charles Coykendale
Port Clinton, OH
TOM NEALE: If it were my boat, I would.
The purpose of a barrier coat is to prevent
blisters. A 25-year-old boat is probably a candidate for blisters. The best time to apply a
know when you flush?

Four Winns, etc.
