On the 41CMY the exhaust mostly exits through the hull under the boat around mid section. I say mostly because there is an additional 2" exhaust outlet on each side at the rear of the boat above the water line which I assume are there for a no back pressure outlet. There are fibreglass deflectors added in this area to divert the exhaust towards the rear as opposed to coming up the sides and also make for a smooth flow while under way. Problem here is when the boat is picked up with a hydraulic trailer the pads can and will come into contact with them causing damage if you do not warn the driver about the obstruction. This damage was there when I purchased the boat and finally decided last week to repair before launch. Not that it mattered all that much but it was unsightly and bothered me.

Here you can see the deflector and damage.



8"+ exhaust hole, no restriction here!



With a piece of cardboard I traced out the part required and cut the new part out from 1/16" stainless plate. Some 5200, a few stainless through bolts with nylock nuts and washers to secure and the job is done. Very content with the results, looks even better after I repainted the entire bottom as can be sort of seen in the last picture if your eyesight is 20/20.



Ready for launching next week.
