Case Ordering Instructions:

Any Material Can be used for the case however I recommend 9600 Resin with Spray Painted Surface finish.  That is proven good.  JLC will probably complain about wall thicknesses, tell them that you accept it as is.   Clear is cool however the material does not have great dimensional stability so warping with clear is possible, YMMV.  Make sure you select "Plastic Enclosure" as the application

Did its job
Got me back onto the water. The mounting holes distances from center to center are less than original equipment. But in a pinch they will do the job.
