Honda personal watercraft forum..

anyone know a good one? I need to figure out why a 1.3/1.4L turbocharger honda marine motor goes rich the second throttles used and shuts itself down

 

I have spent that past 2.5 hrs on that site. I have come to the realize that Honda PWC turbo setups suck! lol The wastegates they use are absolute shit so this is the first thing I will take a look at on the motor and see if theres anything to that!

 

well actually this motor is part of a hybrid river runner. when the last group took it to the lake to test it, they started the engine and throttled up and it just shut off.. so to answer your question i do not know everything about it. there are no leaks after the turbo just that the waste gate stays open which is "why" it runs way rich and shuts off
