We have an '89 Bayliner with a Ford 2.3 liter OMC Cobra I/O. My husband is a fairly handy mechanic (home/ranch vehicles & machinery) but this type of engine is unfamiliar to him. <br /><br />Water is in the oil. Where to start? No visible cracks in the block, but could it be cracked inside? Other than that he mentioned the head gasket. We're only miles from the reservoir but we're many hours from a boat repair to have them check it. I'm worried about bringing it in and having it cost more than the boat is worth. <br /><br />We're having a family reunion in 4 weeks and hope to have it running again, but money is tight so I don't know if that's even possible. Any advice at all is very welcome, including places where we might get a rebuilt model like this online. Depending on the price, I'm wondering if that might be the most cost effective in the long run or if I should start by ordering a manual and possible parts or suck it up and bring it in to the repair shop. We're almost done reupholstering the boat, so I'm hoping there's a solution here somewhere. <br /><br />Model No. --- Ser. No.<br />232BMRMEF --- T1143364<br /><br />Model No. --- Ser.
