Propeller Trouble

When your neighbour with the same boat and motor consistently leaves you for dead, don't imagine the worst! Most probably your out board motor is fitted with the wrong propeller, or it could be that your throttle control is out of adjustment.

If it is out of adjustment you can put it right in a couple of minutes.

However, you need to know whether the propeller is the correct pitch for the load normally carried.

Pitch can be described as the angle or degree of "bite" of the propeller blades and is measured as the theoretical distance the propeller would advance through the water in one revolution. Actually a propeller "slips" a little but the theoretical distance in inches is the "pitch" of the propeller. Coarse pitch pro pellers are generally used on light boats for speed work, and fine pitch props are the "work" propellers.
