of
defense when a wave comes
over an outboard's transom but, in some cases, the well is too low, too
shallow, and/ or not sealed
adequately to the cockpit. Scuppers in the motor well and cockpit may
also
be slow to drain, especially if
they re clogged. And whenever water lingers in the well or cockpit, the
chances of another wave coming
aboard increases. So too is the risk of being swamped."

"A boat is often much "closer" to the water than its freeboard would
indicate. A cracked
thru-hull at the boot stripe or a cutout at the transom for an outboard
motor well that isn't
protected by a splash guard means that, as a practical matter, the boat
has
to sink only
an inch or two before it floods and heads to the bottom. Inspect
fittings
and hoses above
the waterline with the same critical eye that you used on fittings down
in
the bilge. Double-
clamp the thru-hulls and consider adding an anti-siphon loop or check
valve
to any that
are within 8" to 12" of the waterline"

All right, already, we get it. If you don't know how to use a tool,
you probably should not buy it. You should always buy the right tool
for your needs and use in a manner consistant with it's design, and
within the limits of it's intended function. If you are skeeeeeret of
a low transom boat, don't go out in one! If you are in a low transom
boat, take proper precautions, if you are in a big unfloated boat,
take other precautions, if you are in a dinghy.... Don't go out in a
blow... Geeze guys, maybe it's time to revisit your roots, I doubt you
all started boating on 40 foot trawlers



I have a feeling if you were out in a boat with Reggie Retardo or his
clone ROM and you hit another boat's wake, they'd both pee and brownstripe
their shorts.

Got some preliminary performance figures on the new boat:

1000 RPM 4.3 mph .70 gph

4000 RPM 26.2 mph 6.9 gph

4500 RPM 30 mph 8.9 gph


Engine is too young for a sustained wide-open run, but I am guessing 5900
rpm, 40+ mph, and (gulp) 16+ gph.

This is with a 3000 pound boat, 475 pound engine, 50 gallons of fuel
(about 340 pounds), two guys aboard (425 pounds), about about 150 pounds
of assorted "gear." Turning a 15-1/4 x 15" Yamaha black stainless prop
with a 2:1 gear ratio in the engine lower unit. Temp in the 90s, eight
knot breeze, seas calm.


If 16.9 gph is realistic, I think that's quite economical for that setup.

What's the slip figure for that rig, if you know?
