[C320-list] Black Exhaust smoke

[Brad Kuether]

Concur with checking the prop first.

Same thing happened on my 2GM with my previous C&C.

Couldn't get the rpms over 1600 and really thick black smoke.

$75 bucks (diver) and a clean prop, problem solved.

We are experiencing black exhaust smoke, and a loss of high revs with our 
3YM 30 Yamaha motor.
We have only done about 250 hours, the motor is well maintained, boat is 
only 4 years.
Any suggestions of the cause and remedy.
