Welcome to the forum.
was built w/ three of the Apollo Conbraco 65-BF8-XX One-Piece Intake Scoop Strainer / Through Hull
devices, for the A/C and for the engines.
were horrible. It was impossible to pick out the marine
growth from between the slats, even with those organisms dead while the boat was on the hard
, it was a long, difficult process to get that cavity clear of junk.
I use now are the Groco APHS Hull Strainers
along with a regular through hull
. I electrically bond the APHS using a through bolt to an internal bonding wire. The screen
may be unscrewed for cleaning
below. The trap door latch may be unclipped so the through hull
may be cleaned.
To your original question, yes, the A/C should have a scoop and not just a mushroom. An A/C centrifugal pump
is great for moving lots of water
, but not good when the head
(lift) requirement is high, resulting in cavitation (making air bubbles instead of pumping water).
The scoop helps the A/C centrifugal pump work
and NOT cavitate, especially when the boat is underway.
