I have 1988 Four Winns freedom 160 with the OMC cobra 3.0 liter engine. Recently was purchased and was told it does not leak. I took it out about 3 weeks ago and it indeed leaks. I replaced my bellows and seals. It doesn’t leak as much as did before but now leaks out of a small drain hole for the transom. The part is called a bearing plate and is leaking through the middle hole. I have no clue where the water is leaking from and or how it getting that hole. Any tips would help. Thanks
