Bilge pump outfall location??

77SceptreOB · #1 09-19-2009, 01:04 PM

I'm putting a new 1500 GPH Rule bilge pump in my boat to compliment my little 500 gph that currently lives in the bowels of my boat.

I'm running a 1-1/8" line to the outfall.

Question: I want to exit the line on the starboard side, so I can see/monitor it. How high up on the side / freeboard should i exit it?? Too high and it reduces the flow capability due to head loss, too low and it come back in the boat.

Before I go drilling holes in my boat, I wanted to get some opinions and experiences from everyone.

Proposed location on attached picture. What do you think?

Thanks,

Jim

On my 23 Tsunami,I placed the bilge pump thru hulls in just about the same location,as you are thinking of.They work very well in that spot.
I have two pumps,(1500 & 2000 gph)with a thru hull on both the port and starboard sides.

That idea scares me. Completely dependant on the mech. working of the check valve? Doesn't seem very "fail safe".

Is there more to this application?

its just a suggestion but if i were you id get a little more pumpage in there. i like the idea of the automatic ones. ive got an 1100 and a 2000 in my 20sf. 1100 on a float switch and 2000 on manual switch.
