    So I had new pumps put on last week. They ran great before so it was more of a maintenance decision. With old pumps the temp would be around 158 while cruising. When I came off plane they would maybe hit 162-164 for a few mins and then settle down to 158, all normal. With new pumps I’m now...

    I have a 93 Sea Ray 240 Overnighter with 7.4 Merc with Bravo One drive. I was trying to winterize the boat engine myself and had problems getting the antifreeze to go into the drive, and I may have ran the motor too long without water. The motor started to overheat, so I shut it down and let...
