On Holiday had asked me (some time ago!) for pics of where my drain plugs are in my 2000 Mercruiser 5.7L engine in my Cobalt 206. There are 6 that I remove before winter each year. In IL I used to do a full winterization, but with the shorter milder winters here in NC this is pretty much all I do.

A friend just showed me pics of his manifolds with a large chunk missing from each. You can clearly see the bright blue plug beneath in the pics...still in place. He has a Volvo 5.7L in a Chaparral and the plugs are very hard to reach vs mine so he relied on the light bulb method...didn't work this year.

I use a clothes hanger to prop the openings a bit to make sure they are not clogged. I also turn over the engine briefly after they have all drained.

Southern California
A dock neighbor had some bad news when he launched his boat last week. This is at Lake Arrowhead in the San Bernardino Mountains in Southern California. He self-winterizes and stores his boat for the winter outside on his property.

He explained that when he started the engine, there was water spraying all over his engine compartment. He found where the leak was--the power steering cooler must have frozen as the end looked like a beer can with the lid blown off. Yep, it gets cold in them thar hills in the wintertime.

He found a replacement, but hadn't gotten to it before Memorial Day.


Have a great day of boating

Those little pieces will sometimes bite you. Oil coolers, PS coolers, etc..at least that's all it was.

After the first winter with the Chap, I just bought a bunch of brass fittings to replace all the plugs, and attached hoses to the fittings...the other ends of the hoses ended up capped and within easy reach. Just a simple matter of removing the caps and drain out the water, no valves to open. The port riser plug was right behind the alternator so I couldn't put a fitting on that one, but it was a piece 'o cake to remove anyway so no big deal. So that plug, the drain hoses and removing the hoses from the fresh water pump took less than 5 minutes...

The Regal engines have capped hoses too. Nice & easy smile

That makes a lot of sense! Where did you find the brass fittings? Is the thread pipe thread or some other bolt thread?

yup, just basic fittings from Home Depot-

FWIW I didn't remove the brass females that were already in the block, I just took the T-valves to HD and got hose fittings with threads that matched smile

I wrote last year about how the broker who sold us the Regal, how one of their dumb mechanics actually went to the trouble of pulling the drain hoses off the fittings, and I had to put them back on! What a crap job that was! But to be fair to the broker, they may have received the boat like that. Had I known before it left the lot, THEY would've put the hoses back on!

(I used to wonder what on earth anyone would need with 2 foot long needle-nose pliers and screwdrivers I see a Harbor Freight- I now have one of ALL of them! wink )

Regal also put brass garden hose fittings on the hose ends, makes for easy backflushing.

This kind of thing is why I fully drain mine with all the blue plugs, then fill it with pink antifreeze. Costs like 10 bucks. Prior to doing this I was of the "air does not freeze" camp, but one Spring I found a feeeze plug popped out of my block and realizing the huge bullet I'd dodged, switched to the "drain and fill with pink stuff" camp. No problems since.

Smart no doubt, especially in NH. Turned out my buddy's boat down here in southern NC had his freeze plugs pushed out too...in addition to the chunks out of his manifolds.

I can't wait for this global warming thing to kick into high gear so we don't have to worry about winterizing boats every year.
