This thru-hull fitting was delivered the next day and is identical to the 25 year old fitting that finally gave up on my bluewave boat.

Used to upgrade my bilge pumps, boat came with 400gpm bilge pumps with a 5/8 thru-hull. Drilled and installed this with 1 1/8 hoses and bilge pump works great

Was expecting this to fit an 1 1/4" ID and didn't so title description is misleading. This actually a 1 1/8" ID not 1 1/4"
