Hellow I am looking for hot spots to check or methods to find the outdrive leak. <br /><br />I replaced my '86 alpha1 mercruiser outdrive on my '86 Wellcraft Nova 230XL with a refurbished one. Incidentally the motor is a 350MAG (5.7lt). At the end of the second season a small amount of water cameout of the outdrive. The repair costs estimate was nearly the refurbishment costs ($1500).<br /><br />I used the high performance gear lube (it doesn't mix with water) and replaced the water pump. There is no fishing line on the prop shaft,no oil leaking in the bellows, the fill and vent plugs have gaskets. Also, I made sure the oil gasket between the upper and lower units was in place. <br /><br />The only thing I can come up with is the water pump assembly. I only replaced the impeller and housing gasket. Suggestions please.
