One problem that seems to crop up time and time again is the issue of backing down too aggressively, causing the trim tabs to break off.

For those unfamiliar with trim tabs, they’re essentially stainless plates at the stern that help to balance and stabilize the boat. They’re attached to hydraulic rams, which are controlled by a switch on the dashboard. When you flip the switch, the rams push or pull the trim tabs up or down, adjusting the boat’s trim.

But here’s the thing – trim tabs aren’t designed to withstand the kind of forces that are generated when you back down too aggressively – whether reversing by engine, or getting washed backwards in a big wave. Trim tabs meant to be used for fine-tuning, not for full-on backward power moves. And when you back down too hard, you’re essentially trying to rip the trim tabs off the boat

Unfortunately, this is a problem that’s all too common on power boats. The trim tabs are attached to the hull via a hinge and to the hydraulic ram via a pin, and when you back down too aggressively, the force of the water can actually cause the pin connection to break.

So, what happens when the trim tabs break off? Well, the best-case scenario is that the pin breaks, and the trim tab is now hanging down vertically from its hinge. This can be a nuisance, as it’s now dragging in the water and potentially fouling the rudder. But hey, it could be worse – at least the trim tab is still attached to the boat, right?

The worst-case scenario is that the trim tab is completely ripped off the boat, leaving you with a gaping hole in the hull and a whole lot of headaches. So, what can you do to prevent this from happening to your boat? Well, there’s a technique used by fishing boats that might help. These boats often attach a chain or a length of dyneema rope between the trim tab and the hull. The trim tab is now supported by a chain or rope, which is anchored to a padeye through-bolted to the hull. This helps to distribute the force of the water more evenly, reducing the risk of the trim tabs breaking off.

Now, I know what you’re thinking – “But won’t that look weird?” Well, maybe a little. But trust me, it’s better than having your trim tabs break off in the middle of a fishing trip. And who knows, maybe you’ll even start a new trend with your funky, chain-supported trim tabs.

In all seriousness, though, attaching a chain or rope to your trim tabs is a simple and effective way to prevent this problem from happening to your boat. So, if you’re a power boater who loves to back down aggressively, this is something you might want to consider. Just remember, when it comes to trim tabs, it’s better to be safe than sorry.
