The previous owner removed the factory exhaust
and all I have is a blueprint of the factory exhaust
and a lot of questions.
1. The M92 does not have a riser option. It comes with a mixing elbow
and pipe fitting for coolant
to enter the exhaust at the elbow
2. The Columbia
45 used a dry exhaust from the engines to the bottom of a vertical heat riser/muffler which has a fitting for the water
to enter the special exhaust riser.
3. Can I leave the water
inlet plugged in the Perkins
exhaust elbow and run a dry exhaust pipe from the engine
to the base of the vertical exhaust riser/muffler?
4. I am getting a quote to build an identical riser/muffler that Columbia
installed for this engine
. According to the Perkins manuals
it is considered a combination dry/wet muffler
system. Due to the configuration of the boat
it appears to be the only solution I could figure out which is why Columbia probably designed it this way. A conventional water lift muffler
will not fit.
5. Does anyone have a photo
of a columbia 45 CC with a Perkins M92 installed with the facotry heat riser/muffler system? If so, would sure appreciate some photos.
Will attempt to attach a copy of the factory blueprint for the riser. Note, the right hand side of the drawing is the bottom of the muffler when installed on the bulkhead wall (vertically).
I am taking vacation
and working on the boat
so any prompt help is appreciated. Call me if you have something to offer. 909-435-5029 Cell
