I am installing a waterlift muffler with a 2" outlet port. The original transom throughull exhaust tip is for a 1.5" ID hose. So, I either need to find a way to bush down at the nipple on that fitting from the 2" ID hose to the 1.5" OD nipple, or replace the throughull fitting for a 2".
Finding a replacement fitting is turning out to be tricky.
1. 2" nipples on transom exhaust tips do not appear to be standard.
2. I like the idea of a flapper valve to inhibit water ingress, but they don't seem to come that small. A couple of companies make exhaust tips with internal check valves, but I've been warned off inline check valves in general. In this case, it might be hard to know whether the valve was blocking exhaust or had failed completly. An external flapper would be easier to check, and unlikley to caust blockage.
3. I'll have to check next time I'm at the boat, but from the brochure diagram, it looks like the Mark II transom slopes 25 degrees off 90. That does not appear to be standard for exhaust flanges, either.
Any thoughts?

I think that any large plumbing supply shop should be able to equip you with a downsizing pipe converter once you've explained what you want. I can't see backpressure being an issue in a setup like this. Cheers.

After much discussion, I ended up simply ordering a 2" Vetus SS exhaust tip. The flange is 90 degrees to the pipe, same as the original on this boat.
