Parker has used good hose in the past....Not familiar with their new boats. This is good hose -Shields 141 Series,Multiflex Bilge Hose
DO NOT use that plastic segmented crap they sell as bilge hose....It should be Outlawed!
Thru hulls above the waterline get replace with 316 series Polished Stainless to get rid of plastic. I'm pretty picky about the style used for the bilge hose.....Not a straight unit , but a 90deg unit makes the hose conform better.
Best Practice Your Primary Pump should be directly wired with the correct sized fuse I use rigging tape to secure a spare fuse to the fuse holder. It is a 1200 yard hike from the float system to my tool shed.
