Hi,
I have a suzuki df90 year -06 and there is a clanking noise when the engine is warm but only in neutral, when I put in forward or reverse the noise dissapear, still in idle position. I have tryed everything and can`t find from where the noise accour. My idle rpm is 500 rpm on the original tachometer, maybe a little bit low and when I speed up the idle to 800 the noise is a little bit lower, I think!?
In normal speed when driving the boat with 4000-5000 rpm everything is normal.
I am worry that I have some bearing or something else problem inside the engine. the engine have run less than 50 hours.

/Best regards!
