How does boat trim work. Trim is controlled with a toggle button on the control lever or on the dash. The trim system uses hydraulic rams to change the angle of the outboard motor or sterndrive gearcase and with it the angle of the propeller shaft relative to the boat transom through a range of about 20 degrees. It confounds many boaters to the point of distraction.

Trimming changes the propeller shaft angle relative to the boat. When the boat is on plane and the prop shaft is parallel with the waters surface the trim is said to be neutral or zero. In this state all the propeller force is pushing the boat forward.

However this means the propeller handles the power trim which was designed to force the boat in a forward motion. When the prop is used for trim the prop is pushing the boat forward in addition to raising and lowering the stern this increases the prop slip killing your boats performance. Trim refers to the angle of the propeller shaft relative to the boat.

When the boat is stationary and the shaft is parallel with the surface of the water thats known as neutral trim. The prop shafts angle is important because it directs the power from the engine. What you need to do is lower your drive till the trim pump makes that funny noise when it reaches the full down position.

Set the trim sender so that the gauge just starts to read full down position. Put it back on the gymbal ring if you did remove it completly to set it or if you just loosened the two set screws turn the entire sender until the gauge reads full down. Trim Limit Switch Testing 1.

Disconnect the trim limit switch bullet leads from the trim control harness inside the boat see Figure 1or Figure 3. Connect an ohmmeter to the switch bullet leads. Meter should show continuity with drive unit in down position.

How does the trim on a boat work. Using the trim switch slowly tilt the engine up. You should feel the boats attitude toward the water change with a slight rise of the bow a lift of the entire boat and an increase in speed.

The proper method for trailering is to have the engine in a full tilt position and resting on the trailering support bracket then have both trim rams pulled in to a point where the engine makes a jerking motion. At this point immediately take your finger off of the PTT trim switch. Now quickly and sharply tap the PTT up button.

Which pushes the bow of the boat up out of the water. When there is less of the boat in the water and the bow is pointing slightly upward. Thats how come when you trim up the boat may start pulling to the left.

And when you trim down the boat will pull to the right. This is one of the more important things to understand about tilt and trim. Smaller boats with outboard motors will have a manual trim control.

Larger boats will likely have a power tilt option. Begin trimming down as you enter the turn. The more down trim the more the chine is kept in water and the more you can accelerate through the turn.

Develop your skill over time. Maximum down trim not absolute maximum but the max appropriate to the turns speed and radius should occur at the apex of the turn. How They Work and What They Do.

Trim tabs usually consist of two adjustable stainless steel planes mounted at the transom of the boat. Controlled by a hydraulic power unit the tabs can move up and down when activated by the boater. Think ailerons and elevators on an airplane.

Trim tabs do much the same thing for a boat. Tilt and trim adjust the angle of the motor and thus the running surface of the boat so they determine the smoothness of the ride the grip on the water the ability to jump on plane and many other operations that you often dont even think about. Trimming out adjusting the leg away from the transom lowers the stern and raises the bows.

Trim tabs work by adjusting usually electrichydraulically at the touch of a switch the tab up away from contact with the passing water. Or down sometimes also referred to as trimming in or digging the tabs in further into the water. If you press the trim down button you hear the hydraulic noise like something was being lifted or lowered.

If you press the trim up button you hear nothing not even a click. This lead me to a few different conclusions. 1 something is wrong with the trim wiring 2 Trim down wiring is wired to tilt down wiring and Trim up is not wired at all.

Using trim tabs to get on plane is relatively simple. To correct excessive bow rise deploy your tabs down all the way and bring your engine or drive to its most negative-trim position. This should flatten your takeoff angle when you punch the throttle s and offer improved visibility forward.

Once your boat is up on step adjust the tabs to. The trimtilt switch is a 2-way switch and will show continuity only when it is toggled in each direction between two of the wires. Up toggle connects the RED wire to the PURPLE wire and then to the BLUE wire through the trim limit switch.

Down toggle connects the.
