ADJUSTING THE TRIM PLATES
You can also use the trim plates to adjust the ride of the boat.
Bending the plates down will help keep the boat from porpoising
(the front bouncing up and down). Bending them up will make
for a looser (faster) ride but at the same time make the boat
unstable. It is best to make small adjustments one at a time.
You can use a large pair of pliers to adjust the trim plates.
Remember, just tweaking the plates as a very small
adjustment can drastically change the way the boat runs.
BALANCING THE PROPELLER
Always use a balanced prop. An unbalanced prop
will cause high levels of vibration that may be
harmful to your driveshaft and engine.
WARNING: Make sure you use a dust mask anytime
you are working on your propeller. Ingesting airborne
particles from the propeller is hazardous to your health.
