I am in the process of replacing all of my black water hoses and macerator (yay for me). I removed the old hose the other day and amazingly there was Zero smell!!! Apparently after the boat sat for 7 years all of the smell was done smelling
I WIN!!!
Anyways, here is my current problem. The output for the tank is 1 1/2", the macerator input is 1 1/2" the biggest sanitation hose I can find is 1 1/2", My Waste deck fill pump out is........2 inches. The manufacturer just used a 2 inch Exhaust hose
for the black water and just clamped it down to fit the 1 1/2" fittings.
Easy fix right, buy a new deck fill in appropriate diameter. Did and done. My concern once I got it, is the opening that you connect the pump out hose too is much smaller than the old one and since it's been a while, I can't recall if a pump out hose will properly fit a smaller diameter deck fill. Here is the deck fill I bought:

Second solution by a 1 1/2" to 2" hose Mender and just use another type of hose for the last foot or two to connect up to the deck fill. Problem is I can't for the life of me find a hose mender sized to go from 1 1/2" to 2"
Third solution/s and I've never used either so I'm not sure what to buy, is purchase one of these:
www.defender.com
or
www.defender.com
my only reservation albeit a small one, is I really don't want to have to keep, clean, and store in a container my own special poop covered adapter tool just to pump out.
So in summary:
Does anyone know of a 1 1/2" to 2" hose mender? (most preferred so the hardware stays and looks the same)
Will the 1 1/2" deck fill I bought work with regular pump outs? (second preferred)
Should I buy / will the adapter fit and use that? (least preferred)
Lastly as a bonus for all your help
, I did take a picture of the inside of the tank from the bottom discharge port if anyone is interested and wants to see what the inside of a 35 year old septic tank looks like. (don't worry it's not really gross, just interesting)
Thanks All
