Low water pickup

Got a photo of where that clear hose attaches to the motor?

Yes,




On the Rude its easy just copied the reverse feed plate out of 1/4" aluminum & pipe threaded a SS fitting in. This works w/o changing the stock pickup, just adds more water & what the pump doesn't take will run off. The pitot run w/o the hose will send a 1/2" column of water 4'-5' high or more.

Wow! Thanks a bunch. I especially like how it feeds along with the stock pump; I'm workig on a Merc 850 on a Mark 55 tower and was concerned about its small impeller for that size power head.

Thanks again!

I took a 40 yammi case and cut the front off. I put a plate insde where the forward race was. drilled the 5 - 1/4"hole and slots capped the top off and welded it on. Still have that one, it worked great.

You're welcome Jeff. I was looking at your 60 block at the Pottstown meet but couldn't go with another project [sensibly] then. Usually the pumps send up enough & the thermostat regulates so there's the option to change or run without. The extra pickup wont send up more water than the pump would take on its own tho, just so much volume per cycle. The idea is being sure the water is there for it to send.

A nose pick up is the best route if you can do it. that stuff Ive made works but the hose is a vulnerability.

One major problem with nose cones: They capture floating grass like crazy! And, unfortunately, the Elk River is loaded with it.

PS: Those old Merc 'slanters' are immune. Carl had a good idea there.
