I own a 1998 Honda, 90 Horsepower outboard, 4 stroke. Model # BF90 ATLRTA, Serial # 1007073. It has 535 hours on it, and until this year has had no problems. I'm now getting water in the engine oil and filter after only "10 minutes" of running. Enough water to millkshake the oil.<br />Engine has not overheated, still runs good. Thermostat, head gasket and oil pan gasket have been replaced. Head was pressure checked and oil pan was shaved. Spent $1,000.00 at a Honda certified boat repair with no results!<br /><br />ANY HELP WOULD BE APPRECIATED!
