I have a 67 evinrude 40 hp selectric shift. I can get it started but it only runs a few minutes and dies. in that time it will start to backfire a little bit. any suggestions. I have replaced the points, coils, capacitors. I am also having problems with the water pump pumping water out of the water exhaust. I have replaced the waterpump and housing and also pulled the thermastat. help please

Hello Calhouse.Sounds like spot of trouble there.Nothing serious though.First things first.Get a manual.In the bottom lefthand side of this page you can find one.If you are used to technical manuals and working with machinery get either a clymer or a seloc.If that is not your strongest point concentrate on volume 1 Seloc.It will help you in a great way.The coughing probably means that you are running your engine too lean. Choke the engine a bit so the mix becomes a bit richer and see what happens.If that does not help you may have to clean your carburator and the filters.Follow the instructions in the manual and keep us informed.

Thanks for the info. I did go out and bought a manual today. I am presently rebuilding the carb. due to it setting for 4 years thanks again.
