Ballast Pump Mounting

[CJD]

Appreciate the replies! I am sensing nobody has tried the direct pump mounting. The rear transom area is covered with a line locker. If I mount there the locker would have to come out to do anything with the pumps. I am also installing a 4 plate hydraulic wake shaper that will have to use much of that area with hydraulic pumps and lines.

I think I will study and fiddle with the parts for a while, while I install the wake plates, before I finalize a plan. I know it sounds like 1-1/2" hose is not that much different...but the absolute tightest bend you can make is only 16-20" radius, and that is pushing it. That makes planning runs for 6 hoses much more difficult in an already cramped area than you would think. At least if I want to have access to anything related to the engine or drive. MJH, I love your transom mounting! But that would not work with these hoses without doubling the spacing on the pumps and using many 90 degree elbows to get the hoses to them. I would have to staggger the pumps vertically also to get the hoses to run. These fittings are so large that by the time you get through the 90 elbow the pump is already well above the water line. The alternator would go under before them. I mean these fittings are HUGE. To put in perspective, the hoses are almost as large around as the original aerator pumps. Total area used by 25 feet of hoses running to the transom and back to the bags would be the equivalent of finding room for 30 aerator pumps in the engine bay! That's not including the fittings associated with the runs and new pumps.

Direct mounting the pump to the thru hull eliminates 1/2 of the number and volume of hose. It may be worth fashioning a bracket to be able to direct mount them to the fittings...will have to study and think.

I welcome any ideas while I ponder. Thanks again!

PS...Now that I study your setup, I see you just decided to do away with the line locker.
