I'm new here, Just bought a 1987 Wellcraft 19' cuddy w/ 165hp mercruiser/Alpha 1 outdrive from a friend. Hasn't been used much for two yrs. Drove it, bought it, put it away. Next day I found a small puddle of watery green lubricant below the outdrive. It appears to be seeping out of small hole on right forward side of lower unit. I'm new to I/O system and would like to know if this is a serious problem or how expensive it will be to get fixed. Can I drive the boat as is and get it fixed next week? I looked for help in the archives with no luck, thanks!
