5 Basic Steps to Trim a Boat
- 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.
What does it mean to trim a boat?
Trim refers to the angle that your propeller shaft is at relative to the boat. You can adjust the trim so that the angle of your engine is down. This is known as negative trim. Doing this causes the bow of your boat to drop. On the other hand you can chill the angle of your engine up or else.
What is the recommended maintenance for an inboard boat?
one of the simplest tasks anyone can do to maintain their inboard boat, is regular washing. and it doesn’t require any technical knowledge either, so there really is no excuse. if you boat in salt water, wash your boat down with fresh water after each journey. this will help to prevent the salt from corroding parts of your boat.
What are the four sides on a boat referred to?
Let's start with the most important four terms. The front of a boat is called the "bow," and the back is the "stern." "Starboard" refers to what is the right side of the boat if you're facing the bow; "port" refers to what is the left side if you're facing the bow.
What is the tilt of a boat?
Tilt is the mechanism that allows the outboard motor to tip radically forward far enough to raise the part of the motor below the actual engine (called the lower unit) as well as the propeller to the surface or completely out of the water. Tilting the motor up and down is usually done with the motor turned off or in neutral.
When should I adjust the trim on my boat?
Start with trim down: When you're taking off from displacement speeds, most boats work best with the engine and bow trimmed down — this helps the boat rise quickly onto the plane. However, once your boat is on plane, it's important to adjust the trim based on the sea conditions.
How does trim affect boat performance?
Improve speed, ride and fuel economy with basic adjustments. Trimming the outboard adjusts the boat's attitude, or the angle of its bow into the water, which can help dial in the best ride by compensating for vessel load and sea conditions. In most cases, properly trimming also enhances fuel economy and top-end speed.

Why is the trim not working boat?
If the motor operates, then the problem is a lack of power to the motor (faulty solenoid or relay, bad connections, etc.). Failed solenoids, relays and corrosion (at connections, relay sockets, quick-disconnect plugs, etc.) are some of the most common problems associated with tilt and trim system failure.

What is the difference between trim and tilt?
The difference between tilt and trim on a boat is referencing the location of the outboard or the drive of the inboard. Trimming is used when underway and goes about 20 degrees of the way up and tilting is coming all the way up for storage. Did you know there are ways to use your trim to improve your fuel economy?
Should you leave your outboard up or down?
It's best to tilt your outboard up when leaving your boat in the water to prevent marine growth from forming and from corrosion eating away at its metal parts.

Why is my boat on one side under power?
If your boat lists at rest, there is too much weight on one side. It could be gear or it could be water trapped in a stringer bay.
What does the trim tab do on an outboard?
Trim tabs do much the same thing for a boat. They provide lift in order to compensate for changes in speed, weight distribution, and water conditions. When they are deflected downward, the water force on the trim tab creates upward pressure, raising the stern and reducing hull resistance.
Do big boats need trim tabs?
Trim tabs improve the ride for even the largest planing hulls, but on a smaller boat, we may notice the difference more. For instance, bigger boats are much less affected by weight distribution than smaller boats. Once thought to be only of value on larger boats, trim tabs can benefit smaller models, too.

What angle should my outboard be?
The boat motor sits in a neutral position when the propeller is parallel with the top of the water and the motor shaft is at a 90 degree angle. This position normally provides the most efficient operation of the motor and boat in normal conditions.
How Do Trim Tabs Work?
It is a simple thing to adjust them to lift the down side of the boat and compensate for the three or four hundred kilos of weight caused by your passengers all wanting to be on the same side . To do this, lower the down side tab. The water pressing against the tab as you move will lift that side of the boat (around the roll axis ) and eliminate your list.
What is a Power Trim Tab?
Power trim is the ability to quickly and easily adjust your trim with an outboard or sterndrive engine. Sterndrives typically have less range of motion here than an outboard. Not every outboard or sterndrive has power trim however, so don’t take it for granted. Some motors, especially in various older boats or cheaper boats, do not tilt up and down. That said, they can still be adjusted but it takes more effort. A pin in the motor bracket would need to be manually adjusted to accomplish this.
What Are Trim Tabs?
In simple terms, trim tabs are metal plates that can be secure to a boat. They are attached to both sides of the stern. These plates are attached to trim tab actuators. The actuators are controlled either hydraulically or electronically and they are what helps keep the boat level and even as you move through the water. Hydraulic trim tabs and electric trim tabs are obviously more common in more modern vessels.
What Does Tilt and Trim Mean?
Tilt and trim deals with engine movement. You control the tilt and trim by moving the engine up or down as you move through the water.
How Do You Choose the Right Trim Tabs?
The general rule is that an inch of trim tab span or width for every foot of boat length for optimum performance. The depth or chord is recommended at 9 inches if you have a fast boat. If you have a slower, heavier boat then go for 12 inches.
How does trimming a boat work?
Trimming changes the propeller shaft angle relative to the boat. When the boat is on plane and the prop shaft is parallel with the water’s surface, the trim is said to be neutral or zero. In this state, all the propeller force is pushing the boat forward. When you press the trim button down, the gear case moves closer to the transom until it bottoms out at about negative 6 degrees. Now the prop shaft is aimed down 6 degrees, and some of the force lifts the boat’s stern.The boat hull acts like a teeter-totter; when you lift the stern, the bow goes down. Push the trim button up and the gear case rotates away from the transom, and once beyond zero, the prop shaft is pointed upward. In this state, some of the thrust is pressing the stern down and thus lifting the bow. All you really need to know is that when you push the trim button down, the bow goes down. Button up equals bow up.
How to use trim on a plane?
Once on plane, you use the trim to lift the bow so the hull is skimming along on the aft third of the running surface. Bump that trim button up and you’ll feel the steering lighten, the bow rise, and speed increase. Notice that the spot where spray breaks off the hull is moving aft.
Why does my boat bow bobble up and down?
Porpoising — the bow bobbing up and down — is caused by over-trimming at cruising speed ; there’s no longer enough wetted surface to support the weight of the boat.
Why trim the bow in a head sea?
In a head sea, trimming down will soften the ride by allowing the sharper deadrise of the bow to slice through chop. In a following sea, trim the bow up to prevent the bow from rooting (digging in), which will make steering easier.
What are the three control elements of a boat?
Steering, throttle and trim are the three control elements of most boats. Many boaters intuit steering and throttle. Both are analogous to vehicles previously mastered — an automobile or a riding lawn mower. Trim is another matter. It confounds many boaters to the point of distraction.
What happens when you nail the throttle?
When you nail the throttle, some of the prop thrust will lift the stern and help roll the bow down as the boat climbs on plane. Try to get on plane with the drive trimmed up and the bow will point skyward, blocking your view and wasting fuel as the boat struggles to plane off. ADVERTISEMENT.
What are the smaller shafts on a trim engine?
The smaller shafts (stops as you reffered to them) you see are for trim. They move slower & are stronger hydraulically. There should also be a visible switch arm (mine is black). That is for the operation of your trim cylinders. When you lower the engine on tilt it will reach a point where it makes contact with this limit switch arm. At the same time your engine should be close to resting on these 2 smaller shafts. They will stay extended until the switch is made.
