[C320-list] Prop and shaft barnacles

[Dingo Is Talent]

For what it is worth for those with later models MK2 post hull 1000...
I just had same thing except mine was not the Prop but the exhaust elbow off
the motor where the seawater is injected and mixed with the hot exhaust.
It had after 400 hours blocked up with corrosion so the water and exhaust
could not have free flow causing huge back pressure on the motor and
resulting in thick black smoke.

CHEERS
DINGO 'down under' hull 1150

this happened to me last season. i pushed up the throttle because I was not
getting my usual speed or RPMs, then black smoke. A friend told me to check
the prop, and it was gross. Scraper..., and problem gone.
