4.3L OMC with water leak

[mhasselman]

I have a 4.3L OMC I/O with a water leak that from what I can see is coming in through the hole at the bottom of the "V" in the Bearing Plate. Motor runs fine. noticed the problem this year when put boat in water for first time in 2 years. Any suggestions on cause or things I could check??

Try to give another description of "bearing plate", I can't picture where this is.<br /><br />There are online parts diagrams on www.dougrussell.com. Perhaps you could cite a part number.

Re: 4.3L OMC with water leak

The engine is a 4.3L OMC Cobra 1987-88.<br />The "V" plate is #39 on my exploded view of parts of the Transom Plate. It is actually on the inferior aspect of the transom plate on the inside of the boat. There are three holes in this bearing plate-- 2 are for bolts to attach to the lower part of the transom and the third hole is at the point of the "V" approximately 10mm in diameter. This is the hole where the water is running in from.<br />I don't know if something is to go into the hole and is missing or if the water is an indication that a seal or gasket has been compromised.<br /><br />Thanks for your help.
