Title: M35B Exhaust Maniford
Post by: Ken Krawford on January 10, 2021, 04:40:43 AM
I have a friend with a C350 and the M35B engine.  He's looking to replace the exhaust manifold but was rightfully taken back by the prices for a factory replacement.  I suggested looking at Kubota as another possibility. 
His research showed "the M35B engine block is a Kubota model V1305-E which they use in their "bobcats". The only exhaust manifold I can find from them is what I would call a "straight pipe" manifold that you would typically see on a car engine."
Is that correct or is he looking in the wrong place?
Thanks.

Ken K-

The exhaust manifold on the Universal engines are one of the parts that "marineize' the Kubota block  it's from Westerbeke not Kubota. Sorry for the bad new$. What's wrong with the manifold?

Ken Kraw.. :  Valid question - what's wrong with it??  That manifold I believe is cast iron and can possibly be welded if cracked?

Here's a couple of pictures of the manifold.  He noticed the coolant level wasn't moving in the reservoir and found this when the elbow was removed.
