OD should be 2.5” for the through hull tube
Super Jet long exhaust tube diameter and length?

The rubber hose is 2-3/8" ID, so the through-the-hull tube would be the same dimension on the OD. I have seen 2-1/2" OD tube used through the hull, and the SJ exhaust hoses won't work at that point without heating/stretching and such (but things like WR3 hoses will seemingly work fine). Said differently, I have both a stock SJ and an aftermarket hull where 2.5" tube was used in the hull, and the hoses for an SJ won't fit the 2.5" through-the-hull tube. ... but if this is an FX-1... yeah, no clue what the tube diameter there was.

Because the OEM SuperJet Exhaust Rubber Hose is 2-1/4" ID...I just put the Calipers on it
So is the STOCK Yamaha OEM SuperJet Exhaust Metal Tube 2-1/4" OD or 2-3/8" OD? Imma' getting confused
Thats what i'm saying!!! haha
When I built my SN I ordered an OEM through hull exhaust tube for a 1996 Superjet. I dremeled the holes in the hull larger and installed it just fine. However for my FX-1, the through hull tube is angled at the exit, so I cant just use an OEM 1996 through hull tube. I ordered a piece of aluminum tubing and im going to use it, but I ordered 2.5" OD tube. Im gonna be using an AM waterbox and silicone hoses anyway but I wanted to know the actual ID and OD of the OEM through hull tube for a RN

This is correct. The OEM through hull tube for a RNSJ is 2 3/8" OD with a nice flange. I opted to use a 2.5" aluminum tube in its place due to it being much less expensive. I also chose the larger size because it does not have a flange to keep the hose from sliding off. So a 2 3/8" hose will fit tightly around the 2.5" straight tube. Thanks for verifying!
