Actually best I've seen so far demonstration video for the tabs. Thank you.
Thanks for watching, Stan! Glad you found it helpful. Have a fun and safe summer on the water.
Passenger "Sandy" was very helpful. She even wore her life jacket😂😂 Awesome video Mike, very helpful👍👍
Awesome thanks alot that helps alot see ya 😊
Thanks for watching, Ryan! Glad you found it helpful
My left ear really enjoyed this.
Lol this is my first time plugging in a headphone and experiencing yall pain
Great! Quick review!
Thanks for watching!
My next boat comes with trim tabs as a standard feature...but I'm a noob with them. This was a really helpful video & answered my burning questions. Good video- big thumbs up.
Oh, I especially liked that there's no "fluff" in it too. it's concise, stays on topic & gets to the point.
Thanks, Fin Man! We really appreciate your feedback, and glad you found the video useful. We wish you many hours of enjoyment with your new boat. What boat are you getting?

I have a loaded 2019 Lund 2075 Pro-V that'd be trading in & upgraded to a loaded Vexus DVX22. The DVX22 comes wih Bennett trim tabs standard & can be prepped with an Atlas jack plate. Lunds come with neither & I think the performance gains with tabs & a good hydraulic jack plate will greatly help boat control overall.
@@finmanpoozie4756 Nice! Enjoy it!
Job I would have enjoyed as a younger man, could imagine travelling around the world to amazing locations to make specialist estimates & repairs. Expenses paid.
This video along with the engine trim video are very helpful. Thanks.
Are you sure you said correct that you used port trim tab (bow down) to correct starboard listing? I think to correct starboard listing, you need starboard trim tab down.
I thought the same thing and rewatched that section a few times. Seems like adding port trim would increase the starboard list.
The port side trim button controls the starboard side trim tab and vice versa. This should of been said in the video. Only 2 of you caught this but it is key information. Seems like all these other ppl praising the video dnt actually understand what's going on when he pushes that button. They just understand the result but not what's happening under the boat
Great video! I've always found trim tabs are a knowledge blackspot for most small boaters, this should clear it up for some folk!
Thanks for watching and for your kind comment!
Great video! And well explained. I have a question. We have a Searay Sundancer 275 with 300hp. We went for a test’drive’. And when we went to full throttle, the boat was going really sideways, so much it became a bit scary, so we went off the throttle. When we came back we found out 1 trimtab was all the way down and 1 was up. Is this what happens when the trimpads are very uneven? Now we have put them both all the way up, so this weekend we will try again! We really hope the problem is over. And now we know how to use them properly cause of the video!
And also, when we went really side ways, so one side of the boat really lifted up, the engine overheated. And when we went of throttle and cruised back with a low speed, the overheating immediately went away.
I hope this is a problem you heard of before!
Hey Alain. That is exactly what happens when the trim tabs are deployed as you describe. Even them out and you should notice an immediate and drastic difference! Thanks for watching, and glad you found the video helpful
This was the most helpful video on trim tabs, thank you so kindly
You are welcome, Tyler! Thanks so much for watching.
Have 18' Bayliner WA cuddy. Trim tabs have improved ride 100%. Highly recommended!!!
Thanks for watching, Robert. Glad to hear they made boating better for you!
Bookmarking this video so that I can find it again next time I have earphones and can't be sure whether I've got them right way round. If you hear this video in your left ear, you got it right.
Thanks for the feedback, David. This was done quite a few years ago. We have since upgraded our audio equipment. It is a popular video though, so folks will just have to embrace the retro sound. Despite that, we hope you were able to get the info you needed from your left ear.
Why use your port side when your starboard. Listing
Thanks for the question, S&A. Trim tabs are cross wired. In other words, the port switch actuates the starboard tab and vice versa. Thus, in the video the boat is listing to starboard and the port bow can be seen to be visibly higher. The port switch is operated pushing the starboard tab down in the water and leveling out the boat.
Too much drag ,when using trim-tabs to be honest, for luxury only.
say if i pushed all both of my tab buttons up ( meaning that the actual trim tabs were pushed down.) The front of the bow of my boat is down. Does this effect the gas efficiency? If so by how much? (ballpark it for all boats)
Nick - Yes, pushing the tabs down will effect fuel economy, as it increases drag, both on the tabs themselves and by putting more of the hull in the water. Typically, efficiency won’t drop by more than 10%. For inboard powered boats, you actually improve the angle of the shafts relative to the forward motion by tabbing down, but this improvement is quickly offset by the additional drag of more hull in the water. The trick is to listen to your engines. Watch the rpms and the GPS speed carefully after any adjustment. Eventually, you’ll start to find the sweet spots in your running angle that give you better speed at the same rpm.
Thank you for this appreciate it. This was very well explained.
Thanks for watching, Duncan. Glad you found it helpful!
Hi Mike. I'm new to Motor Boats and having spent more time sailing I am a relative novice when it comes to operating these type of Boats properly. I've just become the owner of a Rinker 280 EC (5.7 Volvo Penta 300 HP) and would like to get some advice from you. I was advised that the Outdrive Trim was never used except when coming into shallow waters and never when moving at speed. That all the Trimming of the Boat was done via the Trim Tabs. I have spent countless hours on the internet researching this and most of the information I've found does not support this. Your Tutorials are excellent and I guess you may have answered my question in relation to Andy Sneed. Can you please confirm this form before i do any damage.
Hi William - I’m not certain, but it sounds like whoever told you that may have been confused between trim and tilt. Your sterndrive and most outboards can be adjusted so that the prop ends up completely out, or at least mostly out of the water. On an outboard there are two separate hydraulic rams systems to perform this function. The trim rams (often two smaller rams) and a larger tilt ram, which takes over after the first set have exhausted their range of travel. At that point the motor’s cooling water inlets are out of the water, so you’d be damaging the engine if you were running it tilted up.
You however, have a sterndrive, and with a big V8 pushing that heavy boat, you are going to want to give it all the help you can efficiency-wise. Yes, the trim button is meant to be used while underway. You probably have a trim indicator on your dashboard somewhere. It should indicate the safe operating range. But here’s the thing: the boat will tell you if you over-trim when underway, first by starting to bounce and “porpoise” as you saw in the video. It will get way worse than that if you over do it. Next, the prop will begin to drag air from the surface down and “ventilate.” When this happens the engine will over-rev, with the RPM jumping up right about the time your heart jumps from your chest due to the noise it makes. The boat will slow down as well as the prop struggles to bite.
You may experience a similar sensation if you forget to trim back down before trying to get back on plane, except the motor will be struggling to gain RPM instead of over-revving. Listen to your motor when underway. It will clue you in. Check out this article - you may find it helpful:

Looks great, Mike!
I think the one side audio could use a trim tab.
You win for my favorite comment of the day, Bill! 😂 Yeah, that one was shot quite some time ago, and we clearly had some equipment issues (and not as sophisticated editing tools available) back then. We'll get around to updating it sometime. I promise we've got that situation sorted out since then! Appreciate you watching and having good humor about it!
@@boatus Ignore my comment, the demonstration was excellent!
Short, sweet and well presented! Good Work!!
Thanks for watching, Reed!
educational video, thank you
Thanks for watching, Garold! Glad you found it helpful
Never knew I wanted these until I came here.
Thanks for finding our channel, Ronthunder
Thank you for the video. We own a 20 foot Lund Alaskan boat with no mechanical trim tabs. The only trim tab is the one just above the prop on the outboard, a 115 hp Mercury 4 stroke. When under power, the boat lists to port. When stationary or at slow speeds it sits flat. The list is irritating under ideal conditions and a bit scary in rough seas with wind and waves! I have tried everything that I can think of and worked with the dealer and we are stumped. Weight is roughly equal on both sides. I know enough to know that the torque created by the prop is significant and will effect the way the boat moves through the water. My next step is to put a 50 pound bag of sand on the driver's side and see what that does. Can you give any advice on how to set that trim tab? It was angled toward starboard and now I have it adjusted straight.
Wow, Michael! That's interesting and there's definitely something wrong. It could be the "rudder" zinc under the cav plate if you have one, or maybe your prop is badly out of shape. But those are just guesses without seeing it. Don't discount a deformed or twisted hull, either. We've seen that more than you'd think. Get that checked out for sure--trying to gerry rig it is probably not the safest. I've forwarded your question to our Ask the Experts guru, Tom Neale. He may address it in his column in an upcoming issue.
@@boatus THANK YOU SO MUCH especially for corroborating that it is a pretty big deal and not just some minor irritation!!!! The boat has been like this since we first took delivery of it brand new in 2016. Unfortunately, we have not run it as much as we would have liked to run it. Where does a person go to get it looked at - a different dealer? Our dealer is out of ideas. The Lund company appears to be pretty locked down with no way to contact them directly via their website. All contact links direct users to an "authorized dealer." I also have an inquiry into Mercury but have not heard back yet. We like the boat. We are not looking to jam anyone up - we just want it to run true and safe. We almost exclusively run it on Lake of the Woods which is a big lake with some pretty significant seas at times plus lots of rock piles. Thank you again!
@@michaelwhitt6025 Definitely don't let this go. It's a safety issue.
I spoke to Debbie in the BoatUS Consumer Affairs department. She offered the following suggestions to try, in this order:
1. Ask your dealer for an "area technician." Since the dealer has been unable to correct the issue, this is the next step.
2. Contact Lund's parent company, Brunswick Boat Group. One direct contact we have on file is william.bales@brunswickboatgroup.com. He's in customer service. If you cannot get in touch with him, or he's not the correct person, contact the Brunswick Boat Group Headquarters in Tennessee: 865-582-2200;
boat.inquiries@brunswick.com
3. If the above two options don't get you a resolution, contact Debbie in the BoatUS Consumer Affairs department at ConsumerAffairs@BoatUS.com. She assists members and nonmembers alike with advice, suggestions, and contacts. There are additional services available exclusively for members. For one, Debbie can write a letter to Brunswick on your behalf and try to mediate a resolution if you've exhausted every other option.
In addition, I have two immediate recommendations, if you haven't already done so:
a. Make sure to document everything. Who you've talked to, what they've done and said, dates, expenses. Keep all backup documents, such as invoices and work orders. This will be extremely helpful if you need to go to Steps 2 & 3.
b. Become a BoatUS member. If you need to contact Debbie, the $24 cost is a very small investment for the services she can offer in a situation like this. Not to mention the additional discounts on products and services, the award-winning magazine, and many other benefits. Go to BoatUS.com/Membership to sign up, and scroll down to see all the things included.
Hope this helps, and please let us know what happens!
@@boatus I cannot thank you enough. I will join today
@@michaelwhitt6025 Welcome to the family, Michael. We think you'll find the membership is a great value. Good luck with getting this resolved. Also, you might find this article helpful: www.boatus.com/expert-advice/expert-advice-archive/2019/april/handling-boaters-complaints-the-right-way
what about the benefit of getting up to plane without having to trim your drive? Leave the prop perpendicular to the water maximizing thrust and using trim tabs to keep the bow down.
Thanks for your question, John. Trim tabs aren't the same as planing tabs, which you would find on high-speed racing boats. The primary use of trim tabs is to keep the boat level, or "in trim." When you're using your engines most efficiently, by trimming the engine up at planing speed, your propeller IS perpendicular to the water surface. Doing what you suggest is not the most efficient use of the boat's engine. When the boat is planing and you trim the engine up, the speed will increase without moving the throttle forward. When a boat is planing, you want the least amount of boat in the water so there's less surface friction. If you don't trim it up, the bow will stay down and you'll have increased drag and increased fuel usage.
BoatU.S. I mean just as you are taking off. Use the trim tabs to keep your bow down when coming out of the hole rather than trimming the engine all the way down. Then as u get up on plane you retract the trim tabs. Nautilus has a video showing this is the mist efficient way.
Here watch this let me know what you think. th-cam.com/video/sbOInDmFIVE/w-d-xo.html
Engine tilt still needs to be used even when you have trim tabs. Especially with an I/O since it is centered in the lower portion of the transom
training wheels humbug
Fantastic....you explain the basics so well
try balancing your audio so it comes from both sides...
we're all trim tabs
If you were in a rough chop, would it be best to trim the engine down, along with the trim tabs down forcing the bow down as much as possible? Or would the trim tabs or the engine alone suffice? I have a Dusky 23 CC open fisherman
William, I find the tabs on the boat usually are enough. If you trim the motor down as well, you might improve the ride a bit more, but you’ll have to watch out, as the boat may start to bow-steer, which can be uncomfortable at a minimum, and downright dangerous in certain conditions.
In rough chop trim bow down to just before "plowing" point---ride will be smooth and possibly a little wet!!!
