redfisher4 Posted July 14, 2023 Report Share Posted July 14, 2023 I would like to replace the full assembly from the thru hull to the pumps. I need to know what are the fittings that attach the 90, from the through hull, to the ball valves. I assume these will allow you to preassemble the entire run including the ball valves, strainers and pumps with out spinning the assembly. Is that correct? See pic below. Thanks!

smilemaker Posted July 14, 2023 Report Share Posted July 14, 2023 They are brass pipe unions Can also be had in bronze Quote Link to comment Share on other sites More sharing options...
SCFD rtrd. Posted July 16, 2023 Report Share Posted July 16, 2023 Redfisher4, I notice your strainers are in a vertical position. Do you ever have a problem with your bait pumps "not priming or loosing prime"? Quote Link to comment Share on other sites More sharing options...

fin-addict Posted July 27, 2023 Report Share Posted July 27, 2023 My strainers were vert. also. Never lost prime while running. Yes at times when the boat sat for a period of time, a few weeks. Just loosened the cap a bit and all good. Quote Link to comment Share on other sites More sharing options...
SCFD rtrd. Posted July 27, 2023 Report Share Posted July 27, 2023 When strainers are mounted vertical (like in the pic) they tend to trap air and keep the pump from priming. If you can rotate the strainers slightly down hill, then the air is pushed out or replaced by the water and you avoid air-lock or loss of priming. If you look at it like a clock, the strainers are in the 12 o-clock position. If you rotate them down, between the 4 o-clock and 8 o-clock positions, that prevents air lock. Some boats sit lower in the water than others. If your live-well appliances are below or near the water line, you may never have a problem. The 23 HPS sits high in the water and almost always requires the live-well appliances to be mounted horizontally as opposed to vertical and strainers rotated downhill.
