Replacing bilge question
 

I replaced my bilge and wired it in, the outlet is 1.14” which is bigger than my stock hose. Do they make adapters to fit them or do I just need to upgrade my hose? My stock bilge was an 800gph pump and my new one is 1100gph. I figure that people will tell me to replace the hose so that I don’t stress the system and being a 33 year old boat, that wouldn’t be wise. Where could I purchase it?

Yes they make them, might even find something that will work in the hardware store, but here is one

You replaced the entire bilge or just the bilge PUMP?

pump

The old pump is a tsunami T-800 with a .75” outlet and the new one is 1.14” … seems like a big difference. I’ll probably have to buy more fuses too once I get the adapter.

My opinion and based on manufactures comments on output

A manufacture list a pump at X Gal per minute. Also each manufacture can have different settings (length of hose, how high is the lift) which "lets" them say we can achieve X Gal per minute

OK, a bilge pump is under next to no load. Being under very little load there is little current being drawn by the pump. The pump is not positive displacement so IF the pump is unable to move a given amount of water because of a restriction, this does not effect the pump.

In short, original pump A had a given Gal per Minute, and pump B has more Gal per Minute then pump A. All good, but who knows if pump A was actually able to pump more then B or the other way around. Either way there will be no blown fuses even if it comes close to blocking off the pump output completely
