Hey, what a great plan!
We
live aboard our 31-footer all summer.
Not sure if you need a spare
heat exchanger on a new engine, just
service the one you have at least annually, more if you're using a lot of engine zincs.
Epoxy putty has saved me a few times.
We have a small rechargeable vacuum on board that gets a fair amount of use.
Spare recharge kits for your
PFD.
We keep a small torque wrench and a very large bolt
cutter.
We used to carry a lot of maintence
books, but they're heavy and take a lot of shelf space on our 31-footer. We now download books and
manuals on our
laptop and a spare on the tablet.
UV-resistant zip ties if you're heading heading south.
A few standing
rigging repair devices (Sta-Lok or something like that).
Did you include a jerry can for spare
fuel that you can lash on
deck?
Channel-lock pliers in two sizes (we use these more than vice-grips).
Spare fresh
water pump.
Spare
electric bilge pump and at least one spare float switch.
Spare prop and engine zincs (some engines use a lot of zincs, some don't).
Fender board if you're tied to dirty pilings.
Do you need flares in the
Bahamas? Not sure, but we only carry the new Orion strobe and no flares.
Small door mat.
Do you plan to tow or carry a
dinghy? If so, hypalon or pvc repair kit and
outboard parts.
Small portable AM/FM
radio.
Small
oil pump for changing
oil.
Dielectric grease for all electrical connections.
Thread
sealant for engine
parts.
Spare
raw water pump gaskets.
Jumper cables (also good for lightning protection, maybe).
Rubber hammer (preferrably the ones with the black/white heads).
At least one spare
anchor line.
Shorty wet suit. A full wet suit with
hood can be useful where there are a lot of sea nettles, like in the Chesapeake.
Long
dock lines.
Floating boat hook or bring a spare.
Quart of
bottom paint for touch-up if you have to do a short haul-out for
maintenance.
Navionics or other nav program for your
phone to back-up your chart plotter - cheaper than carrying a lot of expensive paper
charts and they have updates.
We carry a spare prop - our old one before we gtt a new engine. It's not the correct
pitch, but would get us to port if we bend or broke a prop.
Cable and stout, waterproof padlock for the
dinghy and
motor.
If you want to protect that new engine, install a fireport on the engine cover and buy a good gas fire extinguisher that won't damage the engine if you use it.
One really bright big flashlite. We like the kind that lets you focus or expand the beam.
If you can get an injector
rebuild kit for your injectors, carry one.
Stuffing box wrenches.
Stiff brush for scrubbing bottom.
Maybe skip the long line for
overboard self-rescue. Probably won't help. Better to keep very short tethers on you harness so you can't go over the
lifelines and always stay clipped in when you leave the
cockpit.
Spare lenses and bulbs for your nav lights.
Small hacksaw.
BP Blaster penetrating oil.
Teflon thread tape.
Small bottle of bleach for
washing dishes in cold water.
Sail repair tape.
Set of very small screw drivers.
Metric and SAE allen keys.
Long
claw grabber for retrieving small parts from otherwise unaccessible places.
Loktite PL
marine fast cure
sealant.
Water filter and 50' hose with valve for filling your fresh water
tanks.
