I have a '90 3.0 Merc. with the Alpha One drive. It has both transom and thru the Hub water exhausts. The boat was new to me last season and I was wondering how much water should be comming out thru the hub when running on muffs. I get a ton of water thru the transom but just a little mist from the hub. I haven't had any overheating issues at all but I am just wondering if this is something I should be taking care of?<br /><br />Thanks-GREAT Forum-helped me alot with the shift cable change and troubleshooting the drive oil in the bilge.
