Livewell intake 1 inch ID

[Dennis8269]

The hole in my transom for the livewell is 1 inch. All the livewell pumps have a 3/4 inch intake . If I run a 3/4 inch it seems to me it has a better change to leak. Will a 3/4 inch work with proper 3m 4200 around it?

Found a 800 gpm livewell pump with 1 inch inlet. All is good.

Pipe is measured by ID. So 3/4" Sch. 40 pipe is right at 1" OD. Since those livewell pumps have 3/4" pipe inlets, they will fit in a 1" hole perfectly.
