How To Trim Your Boat (Boat Trim Basics)

Автокөліктер мен көлік құралдары

Do you wonder how your boat engine trim works and how to use it properly. We get asked this all the time when we are giving boating lessons. We also see lots of boaters who are not using thier boat power trim incorrectly. In this video we will cover:
0:00 Intro
1:22 Boat design and trim
1:40 How to get a boat on plane
2:09 How a boat hull works on the water
2:50 Best trim settings for boating

    Does your boat behave differently when trimmed vs. not? Tell our follower's about it here.

    My grandfather taught me to trim by watching your wake. No just behind but along the boat. As you adjust trim you'll notice the beginning of your wake moves up and down between the bow n stern . The less wake the better the trim, less boat in the water , less friction, more efficient, more speed.

    I mean, you’re correct, but it depends on tge type of boat. What you’re saying doesn’t hold for stuff like my tournament bass boat, which has barely any part of the boat even touching the water when on plane. The only wake is almost completely behind me. My Regulator 33 center console saltwater sport fishing boat performs exactly as you said. You can always tell by the steering anyway. And that’s all only for calm water. Get out in the salt, or even big water like the Great Lakes, Lake Champlain, etc, you have to trim it for the waves, not just performance.

    To trim your engine properly, tilt up until you maximize your speed which means your wetted surface area is minimized or until your propeller starts aerating, whichever comes first. If your propeller starts aerating, then tilt down a bit.

    The Mercury user manual says that in order to trim the engine correctly, perpendicular to the surface of the water, the steering wheel should not feel a tendency to overturn either to the left or to the right... but at the same time, when you want Go fast, turn the engine up a bit. Very good video, greetings from Argentina.

    I always forget to trim up my stern drive when I put it on the trailer but I’ve just been lucky not to hit the ground before I notice and trim it up (just as it emerges from the water. ). I need a huge red laminated card or some reminder to do that ! 😂. And since we’re sharing I need a reminder to put it down when I launch. Some other trim goodies I picked up this year as a new stern drive owner: the manual says to store it in the down position, even if it’s sitting for “a short storage duration “ so the bellows don’t “take a set” and stay bent in a tight angle. I see lots of boats sit for months with them fully tilted up for trailering. Also a friend of mine who worked hydraulics in the Air Force said hydraulics 101 is to store them with the ram retracted is best (so again trimmed down ). Try not to run a stern drive boat motor (I believe even in neutral ?) with the stern drive trimmed way up because it can be hard on the u-joint in there was another tid bit worth passing on I guess.

    Every boat is different. My chaparral, bravo three would get its best performance (top speed )when I trimmed it up to 2. The trim range was between zero and four. On the gauge anyway. My tritune on the other hand gets its best top speed when trimmed to 1.2. But it gets its best miles per gallon at 23 miles an hour trimmed at 1.4. In the end, just spend a little bit of time figuring all of this out. Every boat is different.

    Hi there ! Thanks for your technical guidance and savoir-affaire in boating issues. I have an Angler 22 with 2 x 250 HP VX series YAMAHA outbards. Quick question : Why is it so, that when I run the boat at mid power and press the trim button down, it clearly accelarates better...? I assume an electrical issue has to do, and if where shall I look to, in order to guarantee unstable electrical power to the spark plugs I pressume...?¡¡?

    In my old 16.6’ aluminum with a 50 Yamaha the revs won’t get all the way up unless trim high enough. Theres a bunch of batteries and gas near the stern so the weight isn’t balanced. Because of this once you trim too high it’ll porpoise so you probably won’t over rev it. Great boat to learn on since there is no tachometer, no trim gauge, no anything. It’s all feel

    So this is a dumb question. I just bought my first outboard, a 88 ranger bass boat v393. When I trim down all the way and I can plane at approx 12-15 mph. Now when I am going slow like 4-8 or so mph the nose is up , seems to be normal, makes it a little more difficult to see while sitting driving but heck, for all I know it's normal.

    Great video,.... question. Does this also apply to a 30 foot 11,000 lb Bayliner Flybridge with a 7.4 sterndrive? I always use my trimtabs but this may be a new tweek. Not sure if the size and weight make a difference. You mention a 25 ft or greater pontoon boat will be different so thats why I was wondering about comparing to my boat. I can get on plane around 26/27 MPH. At about 1.25 MPG I am always looking at saving gas.

    Thanks Thomas. Yes it applies to every boat in general, although the amount of improvement will vary. Your tabs help bring the bow down (getting on plane easier) and the drive trim lifts the bow once you are already on plane. Typically you would reduce your tab setting to (or close to ) zero before adjusting the drive trim up

    How do trim tabs affect the use of the trim?

  • @charlieodom9107

    @charlieodom9107

    Жыл бұрын

    Not much really. You still trim the exact same way. In most properly powered planing hulls, you'll want to trim till you porpoise, then add in tab to stop it. Exceptions to this are sea conditions, loading and balance, and speed. For example: if you are unbalanced, or listing, the tabs will be used to level first, then achieve proper trim, then tab down to eliminate porpoise. Another exception is in rough water, which is where tabs are most often under utilized. You still want to trim for max efficiency, then use the tabs to get a level ride, to prevent porpoise and pounding. Finally, tabs are most often severely undersized on boats, which make them far less effective at doing their job properly. High Performance boats will need a much longer chord than a cruiser or fishing boat of less performance, due to the fact that the plane (tab) needs more leverage and less drag to keep from hindering performance. The best way to understand proper use of tabs is to find a person who has a high performance boat and let them show you how they are supposed to be used. You'll find that nearly all people who use tabs on boats do it wrong.

    After on a plane, I use my GPS speed and engine RPM. With the throttle at a fixed point, say 4200 RPM, I bump the trim to see the RPM come up slightly and the speed increase without a change in throttle position. I also watch the "wash" You want it to be just on the edge of cavitation, then trim it down a touch.
