Hi guys I'm new here but several people have recommend the forum and hope you can help me out!
ok the main problem right now is than on one of my engines (Yamaha 150 HPDI 2000) is giving me trouble, when I accelerate the engine doesn't respond like the other you see it and hear it is not giving what is suppose.
I repace all the spark plugs and notice that on one cylinder (with the engine running) it sparks 3 o 4 times and then it dies doesn't do anything more, i exchange the coils and they are good. can any one can give me a hint of what will be? or where to check???
the other thing is that on the water I go out and they start ok, but the same engine (of the spark) after 20 minutes the RPM go down to 900 top 1200 rpm and from there it does not recover.
Can any one tell me where to check anything???
Sorry of the bad grammar, english is not my mother language!!!
