83, you'll have to pardon Al, they don't have freeze plugs on outboards.
If you look on the side of your engine block (can be in other locations too) you'll see a piece of metal (could be painted over) "sunk" into a boss. They are typically around 1 1/2" in diameter (varies widely), and look something like a frying pan without a handle. These are pressed into their bosses so that they can be pushed out in the event the coolant begins to freeze. The expanding "ice" should push out the plug, hopefully not crack the cast iron block. Emphasis on the hopefully.Your Uncle Bob, Senior Geezer Curmudgeon
It's much easier to promise someone a "free" ride on the wagon than to urge them to pull it.

Okay, so how 'bout these questions:
1) Is it worthwhile to have screw in freezeplugs installed instead of the press in type?
2) Anybody make Stainless freeze plugs?
Years ago I had one develop a pin hole by rusting out. When I removed it (with a screwdriver), I scratched the block where the freeze plug seals, and I still had a pin leak where I gored the freeze plug hole in the block.....can't remember how I eventually plugged it (probably 4 cans of Barr's Leaks), but I'd rather not relive that experience!

Damn.!!.....Streets.. Ya beat me to the punch...The truth about "freeze plugs" that is.....Ya use rubber plugs and blue shit.!!!!!!!...Oh Man .!!! I hate them both...I won't rant any further than that....In a pinch I still use the Dorman brass colored plugs with the acorn nut that expands them into the hole....They stay put.!!.....While out of the vehicle I install the plugs from Mercruiser which are all brass.................................Ok..Ok....Uncle Bob.....tell me this....Where did "Welch Plug" come from when pretaining to "freeze plugs"...I'm serious here.
....And furthermore .....Some American made outboards do have a soft plug... ....Well it's actually a "welch plug" ...(remember the dish type "soft plugs"....It's a welch type dish plug that the S/N is stamped on and tapped into a recess..Damn.!!.....welch plug....freeze plug....soft plug....core plug ?......I never know what to call the stupid things.!!!!.....

Welch plug? Wasn't that the guy married to Rachel?
Yeah, those are the little "dish" shaped guys usually used in soft alloy bodies, e.g. carburetors, to plug holes.Your Uncle Bob, Senior Geezer Curmudgeon

Ok stupid question, I should know better but I don't.
I tried taking out the freeze plugs on my 350 with a srewdriver, didn't work, so I stuck it in the plug to pry it out. just started tearing the plug, still not out. What is the best way to get them out? Nothing seems to be working for me, I even tried a chisel in a drill to twist them out, still no luck.1949 Plymouth Club Coupe Still in pieces.

Thanks streets, I will try that again, I tried a lock pliers or whatever you call it, and all it did was tear it, but I will try it again on another one to see if its just that one I was trying thats a pain in the arse.1949 Plymouth Club Coupe Still in pieces.
