Perkins 4107 / Exhaust Mixer Box Parsons 1.5″

[luigi]

I complete my last post

My Nicholson 38 was built in 1969. Original motor PERKINS 4107.

The exhaust mixer box has cracked.

I must change or replace the exhaust mixer box parsons 1.5″.

Did anybody meet this problem and could help me ?

Does this exhaust mixer box parsons can be replace by an other one ?

Yhanks for your ideas which will help me.

Rainshadow’s previous owner said he had seawater get back into the engine exhaust manifold, and discovered the reason why was a cracked exhaust mixer. His mechanics solution was to repair the exhaust mixer by welding it, rather than replace it.
I do not know the details of what failed, or what welding was required – but you might remove your exhaust mixer and find a welder to ask whether they think it can be repaired. Our repaired welder works great.

Please let us know how this repair turns out.

Hi Jean,
Last year I junked the entire exhaust system and went with Vetus NLP waterlock with temp alarm in hose between waterlock and manifold. Following on I incorporated a vetus air vent venting overside. (if water is coming out of the vent then all is well). In the place of the old parsons I installed a vetus gooseneck which couples up to the existing exhaust hose through to the transom. All costs were quite reasonable and much less than buying a new parsons. It also allowed me to install all new hose from manifold to gooseneck and components fit nicely into the e/r space and in place of the parsons mixer.
I have pics if required.

Thank you Marylin, and thank you Roger for your answer.

I am very interested with the solutions you gave me. Buying a new Parsons is really expensive.

Roger, if you can send me the pictures, it would be great.
Warm regards
