scraping the barnacles from the prop will fix that.

A fouled prop will also cause my engine to lug and
prevent me from
making more thn 5 knots. With the prop clean, my
9.9hp diesel
(volvo-pissoff aka volvo-penta) will push me at
about 5.5.

Don't know about the hull. But you can knock alot
of it off with a
broom by going around the boat. the vast majority
of what will grow
first on our boats grows at the water line.
