Following is a procedure for my boat, yours may vary.
Plumbing
Water Heater
The hot water heater is nothing more than a big tank with an electric element in it to heat the water. There is a drain, a cold-water INPUT and a hot water OUTPUT. Cruisers Yachts uses ¡§Quick Connects¡¨ to attach the hoses.
Most RV places sell Water Heater By-Pass kits. Get one. This basically ties the cold and hot system tubes together and by-passes the whole hot-water heater. The by-pass installs at the inlet/outlet of the heater and uses diverters to ¡§cross-over¡¨. You want to drain every drop from the heater, but it is recommended that you NOT waste 6 gallons of ¡§Pink Stuff¡¨ to fill the heater.
1. Obtain/Install a Water Heater By-Pass Kit (RV places have them)
Note: These kits allow you to by-pass the water heater to keep pressure in the system. They are about $30 and well worth it. Buy it, install it, and forget it. If you don¡¦t, you should fill your water heater with 6+ gallons of ¡§Pink Stuff¡¨. You¡¦ll never get all the ¡§Pink Stuff¡¨ out. Don¡¦t do it.
2. Turn off the power to the water heater. Mark it, so you don¡¦t turn it on when the heater is empty, and zap the heating element.
3. Drain the water heater in to the bilge and leave the drain valve open
Fresh Water System (Pump and Fixtures)
1. Drain all the water from your fresh-water tank and shut the pump off (fresh water breaker)
2. Pull the seat cushions from the aft cabin (access, ya know)
3. Disassemble the feed from the water tank to the pump (under port-side seat)
4. Clean out the water filter there, and make sure it's dry
5. Attach a length of hose to the intake of the pump
6. Stick the hose in to a jug of "Pink Stuff"
7. Get First Mate to watch and have a few of extra gallons opened and ready. I¡¦ve done this myself with a big bucket with 3 gallons of ¡§Pink Stuff¡¨ in it.
8. Turn on the pump.
Note: When you do, the ¡§Pink Stuff¡¨ gets sucked up in to the pump and is ready to be dispersed through the system
9. Start with the shower (furthest away from pump) and run each fixture until ¡§Pink Stuff¡¨ comes out.
Note: First Mate will be swapping bottle of ¡§Pink Stuff¡¨ at a high rate of speed!
10. Don't forget fresh-water wash-downs (we don¡¦t do fresh-water washdowns here in Colorado, but we do do RAW water ¡V see below). Cockpit wet-bar, and anything that is fed from the fresh-water system.
11. Once you¡¦ve run every fresh-water fixture in the boat, the system is loaded with ¡§Pink Stuff¡¨, and won¡¦t freeze.
12. Almost done! Leave the ¡§Pink Stuff¡¨ connected!
Head
1. Visit the pump out and empty your holding tank. Rinse it out several times with a garden hose and get as much goop out as possible. Suck it dry!
2. With the ¡§Pink Stuff¡¨ still hooked up, flush the head a few times until ¡§Pink Stuff¡¨ flows. It¡¦s actually GOOD to flush the ¡§Pink Stuff¡¨ ¡V it lubricates the duck valves, vacuum pump, macerator and all other internal components. And of course, keeps things from freezing.
3. My head has a ball valve for the water intake. I wouldn¡¦t bother closing it, but I don¡¦t see harm in doing so.
4. Leave some ¡§Pink Stuff¡¨ in the bowl
Note: In the winter, you can (in a pinch) use the head. Just pour in the ¡§Pink Stuff¡¨, do your business, and flush. Do NOT turn on the fresh water system. Emergencies only!
Genny
A generator is just an engine that has a mag attached to it¡K.but it¡¦s water cooled (raw-water in most cases). You want to change the oil and flush the cooling system with ¡§Pink Stuff¡¨.
Since you¡¦ve disconnected the raw-water Sea Cock , the cooling for the genny is not there... You¡¦re going to replace it (temporarily, of course) with ¡§Pink Stuff¡¨. You don¡¦t want to run the genny for more than a few seconds¡Kbut the water pump will suck up ¡§Pink Stuff¡¨ and shoot it over the side.
1. Clean out your sea strainer
2. Fill the sea-strainer with ¡§Pink Stuff¡¨
3. Attach a temporary hose to the inlet side of the strainer
4. Stick it in a bottle of ¡§Pink Stuff¡¨.
5. Start the genny, and have First Mate watch the thru hull
6. When ¡§Pink Stuff¡¨ comes out, you¡¦re done. You should fog engine while pink stuff is going in.
7. Don¡¦t forget to change the oil, filter, etc.
8. Done!
Engines, Raw-Water Cooling, Power Steering
Four main tasks here ¡V drain the blocks, manifolds and power-steering cooler/raw-water pump, and ¡§Fog¡¨. Each engine type (Merc, Volvo, ??) will be slightly different, but they all work the same. Check your manuals and adapt as needed.
Fogging is the process where you introduce fogging oil in to the engine by removing your spark/flame arrestors and spraying this oil in to your motor.
1. ¡§Fog¡¨ each motor with your favorite stuff¡KI use ¡§Merc¡¦s Fogging Oil¡¨. While the engine is running, and the pink stuff is flowing in, spray this gunk in, and pinch off your fuel-line so that the engine gets the oil and not fuel. When it dies, you¡¦re done.
2. Change your motor oil, filters and water-seps. My Volvo¡¦s have screw-fittings on the dip-sticks that I hook my Jabsco oil-sucker ($150 from BoatUS/Wests).
3. Drain your blocks and exhaust manifolds My Volvo¡¦s have all the drains connected to one hose. Late-model Mercs have blue plugs. Pull ¡¥em all.
4. Disconnect your raw-water pump inlet hose. Volvo¡¦s are mounted on the crank. Like the water heater, there is a water INLET and a water OUTLET. Volvo¡¦s also have ¡§riser¡¨ bumps that keep the ocean from rushing in.
5. Hook up to a tank of pink stuff and run engines.
6. When pink stuff is flowing steadily out, fog engine and shut off engines.
7. Done!
Consider removing the outdrives for the winter.
Air Conditioning/Heating
Your AC/Heat is a raw-water pump too. Since you¡¦ve already blown your cock, you¡¦re going to follow a similar procedure to pump ¡§Pink Stuff¡¨ thru the AC unit until it goes overboard. AC equipment (Sea Cock, Raw-Water Pump, etc) is under the floor at the bottom of the Companion Way ladder.
1. Clean out your sea strainer
2. Fill the sea-strainer with ¡§Pink Stuff¡¨
3. Attach a temporary hose to the inlet side of the strainer
4. Stick it in a bottle of ¡§Pink Stuff¡¨.
5. Turn on the AC and have First Mate watch the thru hull.
6. You¡¦ll hear the water pump turn on ¡V it¡¦s right there.
7. When ¡§Pink Stuff¡¨ comes out, you¡¦re done.
Miscellaneous
1. While you were working on your AC, did you clean out your shower sump pump? It¡¦s a nasty job, but you gotta do it. Fill it up with ¡§Pink Stuff¡¨ and trigger the pump until ¡§Pink Stuff¡¨ squirts of the side.
2. Pour ¡§Pink Stuff¡¨ in your drains
3. Clean your bilge(s) and dry them completely. I could lick my bilge - can you? ļ
4. Wash-n-wax the whole boat.
5. Remove anything that might collect mold, mildew, or other stinky stuff
6. Did you tag circuit breakers for things like Fresh Water, Head, Macerator and things that you might turn on that are now loaded with ¡§Pink Stuff¡¨?
