Maxum 3500 Exhaust junction - Maxum Boat Owners Club

Hi guys
Im a new owner of a 3500 and have work being done on the 8.2 Mercruiser motors. The three way exhaust junctions are cast iron and are in pretty bad condition. Can anyone recommend a stainless steel replacement? I am based in Australia but think it is easier to get these from USA

Cheers for the help

Stainless Marine makes aftermarket SS exhaust systems. There are a few companies out there. Most are targeted towards the high-performance market.

Welcome Aboard.
I try to find something for you but no luck.
My suggest is to take it to a welding shop and let them to make it for you from S.S.
It's not a big deal for them to make it.
Good luck.

I also have a 35 Maxum and i would stick with the cast iron exhaust junctions. I had stainless extractors fitted a number of years ago but the quality was poor and they cracked. I recently had to have everything replaced with the original cast gear. Some of the old salts now tell me there is no place for stainless in the engine room.....................Incoming..
