Ok so I am having some starting And putting in to gear issues with my 2011 evinrude etec 200 2.6 V6. The motor will start, and when I put it in to gear will immediately shut off occasionally. I have replaced the exhaust back pressure fitting, cleaned brass restrictor, and replaced hosing for both due to carbon build up, replaced crankshaft sensor and throttle position sensor. On another note the boat always starts easier when it is hooked up to the hose and not in the water under load. Also I noticed that the boat will go in to gear without shutting off better when using A raker prop vs. tempest Both of which were 24P which is very odd to me. Possible exhaust build up maybe?? Boat has a poor holeshot but runs great once it gets high in rpms. Only other things I can think could be the issue is reed valves or injectors. I have had the boat serviced along with new plugs installed and indexed
