Hello. Could anyone help me out before I buy a boat with the 3.0 Mercruiser. The boat itself is a 99 maxum. Its a one owner and it has sat for the last 6 years he took it out this year and it ran rough but all that was done was new oil and topped up the old gas. I really know little about boats but want to learn. The overall price is really really good. It does need a good cleaning as it has been neglected for those years. Is this a engine that is good and could use very little to tune it back up or could I end up needing to put thousands into it? Thanks for any input.
