330 hp 454 lost freeze plug over winter
 

had checked no water or cracks install rubber scew in plug. i only run in fresh water lakes. marina told me the temp plugs are fine as long as the are replaced every winter until there is a reson to pull the moter and then install regular plug does this sound right to you all????

I have used the rubber plugs before but only for temporary repair. I have seen them come out. A good way to end a fun weekend on the lake. I would install a brass freeze plug as soon as possible. Better make sure you dont have some others on the way out too.

My 2 cents worth.

If you can get to the freeze plug to put in a rubber plug , why not just tap in a real one. I had a 211 Liberator that this happened to. All the plugs on one side were in the bilge. It had a removable back seat so I fished them out , Permatexed them and tapped them back in place. That was May 1993 and except for a few years the engine sat idle due to a 540 in the boat , it's been back in since 2000 and still fine:cool:
