Winterizing our 318 hints to share

"Hi all. As described in a previous posting, the original (1969) owner's manual is a little sparse in its description of maintenance methods for particular aspects of the 318 engine.
Now that our boat is out of the water and back under shelter for the winter, does anyone have any hints to share for winterizing the motor to avoid cold-weather damage? (Getting antifreeze to all the necessary spaces, fogging, etc.?) Our boat shelter is dry, well-ventilated and completely enclosed, but unheated.
Thanks in advance for any help you may share!

Assuming raw water cooling:

1. After changing the oil and filter, drain block, manifolds and risers, then re-install the drain plugs.

2. Remove and toss out the t-stat(s). Pour the motor full of Pink stuff and stick the t-stat housing back on with the old gaskets.

3. Pour pink stuff in the strainer (if possible) or hose to the raw water pump. Run engine 'til it comes out the back.

4. Pull coil wire and wheel her over for 10 to 15 seconds while spraying fogger oil into the carb.

5. Put in a new t-stat and gaskets.

6. Duct tape the exhaust and the carb openings.

And don't forget to winterize the water system!

Don't forget fuel stabilizer. It used to be recommended that you add fuel stabilizer and top off the tank. Now, with ethanol in the fuel, I siphon the tank down to near dry, then I mix Sta-bil http://www.goldeagle.com/sta-bil/index.htm at the recommended ratio with 5 gallons of gas in a jerry jug, Then pour that back into the near emtpy tank. I start the engine and run it for at least 15-20 minutes to get the fuel stabilizer up in the the fuel pump and carb. After fogging the engine. I siphon what's left in the tank back down to as near as empty as I can get it. (That goes in the fuel tank of my truck.) It worked out well last year. No water or ethanol separation / emulsion problems.

One more thing. I bought the Sta-Bil at Pep Boys for $14. It was $20 for the same bottle at West Marine.

"Hey thanks, Chuck!
Yes - I've been told similar things at Power Squadron meetings up here in Ontario: Ethanol loves to attract moisture over time. And the same advice - stabilizer to avoid future problems.

It's another day closer to summer... ;)"

"I came up with a way to winterize my Chrysler 440s. I fill a 5 gallon bucket with "pink stuff" and hold it below my engine exhaust. I put a submersible water pump($30 Harbor Freight)in the bucket and run a garden hose to the engine water intake inside the boat. I adapted a male garden hose connection to a 1'1/4" pipe. Disconnect the engine intake hose from the through hull fitting and slip in the adapter/garden hose. Plug in the submersible pump and fire the engine up. The pink antifreeze will circulate through the whole engine and come out the exhaust and back into your 5 gallon bucket. After it has warmed a bit I spray fogger into the carburator and shut down the engine. I try not to let the pump run while the engine is not running to prevent any chance of antifreeze entering the cylinders. I have done it this way for 25 years and never had a problem. If you have another engine,just move the rig over and repeat.

P.S.

Home Depot has the Stabil fuel stabilizer (treat 80 gallons) for $9.95 in the weed wacker section. They also have 3M 5200 in the glue section for $9.95 ($20 at West Marine).

"For my FWC 318, I start by checking the anti-freeze in the heat exchanger with a hydrometer, to make sure the mix is 50/50 adding a little anti-freeze if needed to assure sufficient freeze protection on the fresh water side. I warm up the engine, letting a garden hose run into the top of the raw water strainer (see notes from my earlier post in this thread on fuel stabilizer). After changing the oil, I start the engine with assistance from my wife who pours four gallons of pink stuff (one at a time)into the strainer while I monitor the exhaust to make sure the non-toxic antifreeze is flowing through the system. By the time she gets to the third gallon, and I've confirmed the pink stuff is flowing full strength out exhaust, displacing the fresh water in the raw water side of the cooling system, I slowly pour about 8 oz of mystery oil into the carb, which fogs the engine. Finally I remove the spark plugs and squirt a little oil into the top of each cylinder, replacing the plugs finger tight, then crank the engine briefly to coat the cylinders.

I like Captain Ed's pump system which recirculates the antifreeze, but he must have to decide when to place the bucket under the exhaust, because when the engine first starts there will still be raw water in the system, and you don't want to dilute the antifreeze. It would also be a little more tricky for me because I have dual exhaust and would need two buckets to catch the outflow.

I also appreciate the price tip from Captain Ed for an even better buy on Sta-bil & 5200!
Keep warm.

"A couple of final things. I also loosen the belt on the alternator and water pump, and pull off the raw water pump to remove the impellar."

"Marty,

It's easy to get confused because some people talk about standard (or normal) rotation and others refer to left-hand [LH] and righthand [RH].

You might need to crank the motor to see which way the flywheel rotates.

You should generally post new questions in a fresh topic which makes answers easier to search by others.
Good Luck

You can look at the serial num

You can look at the serial number of the engine;

LM318 is Left hand

RM318 is Right hand
