10 Meter Exhaust Manifolds

Replaced the manifolds, risers, elbows and exhaust hoses on both engines in my 10 meter over the last couple of weekends. Wasn't to difficult, old parts came off pretty easy, just heavy!! The port engine may have had the original manifolds from 1985. They were the old design that had a bolted on water inlet. From what I read they stopped making that type in the early 90's. The starboard side had been done at some time, all the parts were aftermarket. At that time I also replaced the valve cover gaskets and all water cooling hoses. I only had one small drip when I started them up. Took the joint apart removed the old (new) gasket, put on some more gasket adhesive and put on another new gasket, that seemed to fix the drip. This boat lives in salt water, both engines have a fresh water adapter flush kit. I plan on fresh water flushing after every use, is it worth it or am I just wasting water?

Yes, the manifolds are heavy- especially if you have to remove them with the risers still attached!
I have fresh water flushers on my strainers too, I don't always flush but after a long trip I will. If I weren't so lazy sometimes, I'd flush after every trip. If you have easy access, are in the mood and have time after using the boat, I would flush.

Glad to see you got your mission accomplished!

I flush mine fairly religously after each use when putting the boat up on the lift, but not if she is in the water fr a few days.

Religous is the right word as thos ealuminum Yanmar components can be expensive to replace

The fresh water flush costs only your time.
