How long do the shafts last?

I lived right smack dab between the Mississippi and the Merrimac for =
three years...the Mississippi is a muddy, muddy river and if you don't =
service your engine continuously, it will go shot quite quickly. People =
sail up north of St Louis and I've heard that sailboat engines suffer, =
too. Running the Mississippi through your engine is like pouring mud =
through a fine sieve.=20
