Engine Leak

I got a problem, I started my boat and found a leak. There is a hole in my block. There is a hole in the block just above the starter on my 1994 prostar190. It looks like there should be a plug covering this hole and it is just gone. Any help would be great. There are like 6 or 8 holes just like it, but they all have plugs in them, but I dont have a clue what they are or how to fix them.

That is a "Freeze plug", you prbably had some H2O left in over the winter and it froze and popped. Find the plug and use some GASKETCINCH around the edges to help seal. Let it sit for 24 hrs. Fire the boat with the a fake a lake and check oil, if it looks like YooHoo, you cracked the block or a head. Also check for fuel in the oil.......Some will say they are not Freeze plugs, but i built race engines for 5 years and thats what we called em'

If its brass in color ( or painted over) its most likely a freeze plug. Leaking water i assume? You can pick up a freeze plug any where. I don't think theres any difference in plugs for marine engines but double check with your local dealer. You shouldn't have a prob knocking a new one in if you can get the old out without messing the block up. Good luck

Woohoo Todd agree'd with me

"if it looks like YooHoo, you cracked the block or a head"
Thats a keeper!

I've just had to replace mine on a 190 pro. They are easy to do as long as you can get a swing of the hammer in there. Just use a socket to tap it in.

Yeah, what Todd said, especially about fuel smell.

The good news is there's not much pressure there compared to a car motor.

Any freeze plug will work as long as it's the right size.

There is no such thing as freeze plugs..Those are casting holes!

B-

Here we go again..................

OK, so, the BLOODY casting plug fell out due to water freezing.

Same fix.

are they freezing casting holes??

I believe it's frozen casting plugs? hehehe.

Blah blah!
