You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.

Why would a fouled prop cause black smoke?

with a fouled prop, the engine gets bogged down with the throttle wide
open because of the heavy drag of the fouled prop the engine RPM can not come up. the overloaded engine will put out black smoke-- it is like when you see an 18 wheeler going up a hill & the driver doesn't shift down soon enough the same think will happen with a prop that has too much pitch, the engine can never get up to rated RPM

The amount of fuel being injected is too much for the rpms the engine is turning and therefore there is not enough air to properly burn the fuel.
