I believe the engine is fresh water
cooled so that might the fresh water, right? or sea water? if fresh water I could dump it out and repair the place ... but what if it is sea water? seacocks are permanently open [plan to clean them but not now]
any ideas welcome ... I was planing first trip today as the alternator
was the last thing to hook up ... and know this issue
thanks a lot, tomas
You broke the pipe plug
& zinc anode assembly.No big problem.It definitely was not the original plug
The part that is still inside the block is probably the zinc anode,& it is not required in a fresh water cooled engine.If you can get it out with needle nose pliers-OK.If not,don't worry about it.
You need to find a brass or steel
1/4inch NPT pipe plug.Common in North America,but you may have to check refrigeration
supply shops,etc.elsewhere.Same size BSPT British Standard Pipe Taper plug should work also.
Put some pipe dope/thread sealer or teflon tape on threads of new plug & carefully screw plug into the hole by fingers.If threads in hole are still OK,you should be able to screw plug several full turns by fingers.
If you cannot do this,you may need to repair the threads with a 1/4 NPT tap tool.
Be very careful that you get the new plug started straight by fingers.
Once you have it turned in several turns by fingers,use a wrench to tighten it further.The threads on plug are tapered-small at the end & larger as you screw it into hole.Do not overtighten it.The amount that you can apply using your wrist only is plenty.
Refill the engine with automobile radiator antifreeze
.Never use just water,except in a temporary emergency
inhibitors & lubricant that is required by water pump & engine.It also helps prevent boil over & cools engine better.
If all else fails,I see in pic that you are using the "wood plug" trick.This will work in an emergency
,but I would not trust it very long.
With my 2003,I installed a Temp.guage sender in this hole.
Good luck / Len
