Had 1" thru hull scoop strainer on my grady feeding both washdown and livewell pump (water puppy impeller vs diaphragm). Water puppys dont last in a wet environment though good for 1-12 yrs the diaphragm pump would be the backup when the other failed, 5 impeller pumps in 10 yrs and 1 diaphragm in 10 and still going strong
never had an issue with drawing water from either at about a 2 1/2 to 3 ft
Just added a 3/4 to the V20 last week, planning one pump for both
