Here's a quick rundown of how I winterized my 268 last season...
I have done it myself every year, and it is a breeze. I just checked, and the fluid transfer pump I bought from Harbor Freight is no longer available. A cheap one will work..no need to spend the dollars on the Jabsco.
I bought a new tube for mine, a hardwalled plastic tube from Lowe's that fits perfectly on the pump end and also on the oil dipstick tube. I do not run the tube all the way down it. I heat up the engine on the garden hose, then extract the oil. Do the oil change, and then empty the block off all water via the drains at the bottom of both side of the engine block, and also the exhaust manifolds. Stick a small screwdriver in there to make sure nothing is blocking the holes and they drain completely. I also remove all hoses from the water pump housing at the bottom front of the engine and let those drain completely. Then put those back on. I leave the exhaust manifold and block drains open so they can let pink flow out, then seal back up. Make sure you remove the two hoses running to the water heater. Forget those and the water heater will burst!
Remove the hose from the thermostat, and start dumping in pink until it comes out the drain holes. Thats it for the engine. I like to drain the pink out to help get the water out of my bilge...and air won't freeze. My boat stays in the fairgrounds barn over the winter so its not heated, but I just use the pink -50 antifreeze. I still have a case left over from last year!
On to the drive. I built a drive stand out of a 2x8 and four casters. Very easy to use and lets me get the drive off.

Take off the 6 screws as well as the shift cable and it will come off no problem...no lifting even. I bought a alignment tool off eBay for about $30 to check my alignment. Do that and check the bellows for wear (I think I'm changing mine this year as they are original), then put the drive back on.
Remove the props and drain the fluid out. Refill the fluid with a drive oil pump, and then grease the prop splines with Volvo Penta prop grease. I bought the jar of it for a few bucks and have enough to last for the life of the boat. It sticks on there well, and isn't harmful to the environment. Be careful not to get metal splinters as you spread it on the splines.
For the head, I just pump it out and pour a gallon or so of pink down it. Same with the shower sump, pour pink down the drain tube until it comes on and pumps it out.
I take a funnel and a plastic tube, and stick it in the A/C through hull on the side of the boat. Pour pink in until it comes out the bottom of the boat. Verify the strainer is full of pink. The genset is the same...warm it up on the garden hose (open up the strainer and stick the hose in, turn it on full blast...make sure the seacock is closed. The genset will use less water than the hose puts out). Change the oil/filter/spark plugs, and then run it again to check for leaks. Stop it and then as you start keep pouring pink into the strainer. Have 2 gallons ready..I think it takes just over a gallon to suck it all up.
Now the genset is done.
Last but not least..freshwater system. Run your faucets until your tank is empty.

I leave the drain open over the winter. Make sure the bypass valve is turned so you don't get any pink inside the water heater.
Buy this and install it right before the water pump. You want it to draw directly from the bottle of pink so you don't get any in the water tank and get the tank contaminated. Its non toxic but a bear to get out of the tank come spring time. Turn on all faucets (galley/head/transom) until pink flows out of them.
Buy this,

On the trailer I just make sure to grease my bearings real good in case any water got it.
