Ok im going to chime in ,I have another post on here in regards to cooling water restriction, My bravo transom assembly has corroded the water inlet almost shut. I was looking into putting a transom mounted water pickup on the boat because repair of the restriction with the motor in is very hard.Now Imco and Latham have some nice pickups but it seems a little tricky getting these systems dialed in. The amount of distance betweenthe bottom of the pickup and the bottom of the boat. As much as we hate to admit it mercury must put them like this for a reason just like drive showers . If showers did that much would merc. put them on at the factory ,they dont cost that much. Also some say picking the water up in the drive and moving it through the drive help keep it cool.
