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 cruising at 162 and when I come off plane I spike to 175 (port) and 172 (SB) for longer than a few mins. I’m not pushing her hard either. Another huge difference is the steam amount. It’s super noticeable even at the dock warming up or pulling up to other boats to raft up. Way more steam than previous pumps and more than any other boats around me. I know the water is cold still and there will be more steam but this is over the top. So much so all my dock neighbors question it.
Strainers are clear
Mechanic said it’s all normal over text messages but my gut feeling is it’s not normal.
Any suggestions
