Check Catalina 30 website
I presume the previous owner did not do it themselves, otherwise that would be the best source of information. I have an 88 Catalina 30 and below is what I do. ALso try the Catalina 30 website (see link below). Assuming all standard equipment, it's not difficult. Consider breaking the boat down into 'systems', and then attack each one. Here's a short list off the top of my head: 1. Clean/dry bilge before haul-out. 2. Clean head. 3. Top-up fuel tank (add Biobor algacide) and empty holding tank. 4. Engine -- run engine, change oil and oil filter, then after haul-out, drain water lift muffler (put a paper towel under drain to keep the ick from the bilge), then remove raw-water hose from strainer, insert in a 2 gallon container full of Camco Banfrost 2000 and run the engine just long enough to suck-up most but not all of the 2 gallons (I use a Poland Spring 2 1/2 gallon container set in the bilge and fill it with 2 gallons of anti-freeze). Then drain the water-lift muffler again, allowing anti-freeze to fill-up the bilge and leave it there for the winter. Then remove raw-water impeller, clean and leave out to 'unset' over the winter. If you have the original 'Sherwood' pump, there's a 'e-clip' holding the impeller to the shaft, and both can be removed together, BEING CAREFUL to not damage the impeller vanes, try only grasping the center rubber hub. if you didn't already, pull the impeller shaft, lightly lube it with Lubriplate, and re-insert it gently while lightly spinning it until it engages the cam's tang. Then buy a new impeller cover plate gasket (newspaper thin but required) for the spring re-install. Also remove the rubber 'anti-siphon' valve cap (under galley sink), clean the rubber duck-bill insert, lube (Silicone spray) and reinstall. 5. Water Systems – run water in galley to drain both tanks. Assure both are empty, if needed, temporarily close the empty one if it prevents the other from draining. Open front tank and Shut down side tank. add 2 gallons Camco Freeze Ban 50 to front tank, and 9 gallons to starboard tank. Run hot water in galley until front tank is empty (you will hear the pump start to run faster). Shut down front tank, open side tank. Continue running hot water in galley until strong pink color. Then run hot water in head until strong pink color. Now the 6-gallon hot water tank is protected. Then run cold water in head until strong pink color. Then run cold water in galley until tank is empty. 6. Toilet Systems -- Close sink drain's thru-hull. Add 2 gallons Camco Freeze Ban 50 to Sink while opening toilet valve and pumping through the Jabsco toilet until dry. Leave the toilet valve in 'open/flush' position to de-stress the flapper seal over the winter. Then open holding tank/macerator thru-hull and run macerator just long enough to verify 'pink' comes out of though hull on the port side. 7. Cooler -- add 1/2 gallon Camco Freeze-ban 50 to cooler. Open galley thru-hull and operate foot pump until cooler is empty. 8. Cockpit drains -- Remove deck cover plate over wheel/rudder radial drive wheel. Clean-out area underneath and assure the drain therein is clear. Add 1/4 gallon Camco Freeze-ban 50 to recessed area and assure it drains out. Add 1/8 gallon Camco Freeze-ban 50 to port/starboard cockpit drain hole and assure it drains out below. 9. Cover boat -- at minimum cover cockpit area to prevent snow/ice from building up and getting into cabin (I prefer completely covering the boat to keep snow/ice off the decks too, even all the way to the water line to protect the gel coat, especially since UV is worse during the winter). 10. Spring Engine before Launch -- reinstall impeller with new cover gasket (a new impeller each year is cheap insurance -- consider a Globe brand which can run dry without damage --- for Sherwood it's # 1130 available from Defender). AFTER launch and a couple of sails/engine runs, change both the primary (Raycor) and secondary (Universal/Westebeke) Fuel filters (remember to close fuel valve on tank while changing filters), also the M25XP is self bleeding, you only need open tank valve, open bleeder on the top of the Raycor filter housing till fuel comes out, then turn on key BUT don’t start the engine, and temporarily open knurl knob/fuel bypass on top starboard side of fuel lines and let electric fuel pump ‘bleed’ the system for you (pump will click fast at first and then slow down to a normal speed after a minute or so). This way the fuel tank gunk from over the winter is sucked into the old filters you just removed and you will have nice clean filters for all summer long. Happy Sailing. Hope this helps.
