Author Topic:   Dauntless 16 Trim Tabs

I recently bought [a 2001 Dauntless 16] and noted porposing when my wife or son went to the back of the boat. I had no more trim left on my engine. I missed this during the sea trial.

I put on Lenco trim tabs, and what a difference. No more porposing, real fast [acceleration onto plane from a standing start], can stay on plane at very low speeds, and, of course, minor adjustments for weight are a snap. I really enjoy this boat, but the tabs change everything. Now it's handling characteristics are hear perfect.

I have a Outrage 23 that I bought with broken hydraulic tabs. I now think I will put some Lenco's on it too.

I'm glad the tabs worked out for you on the 16. If the boat porpoises it can be cured easily without adding tabs by trimming the engine IN. If trimming in fails you may want to look at your propeller and engine mounting height.

Even with tabs the right propeller and mounting height can make a positive contribution. What engine is installed on the boat?

I have a 2006 Yamaha F115. The engine is [one-hole] up. I have an Apollo XMS 13 1/4 x 17 propeller. I read about different propellers and raising the engine on this site, but I noted that some folks still had porposing. Somebody else here used tabs after all else failed with great success also. Perhaps the transom notch makes it more challenging.

I don't know anything about Apollo propellers. Not sure if this prop was exacerbating the issue.

I would not have thought that trim tabs would be needed on a 16 foot Boston Whaler but I have a Dauntless 18 and the brochure shows them as optional equipment so I guess they knew that they would help.

I have a dauntless 16 with 100 hp Yamaha, which had the same issue. Raised the engine 1 hole from the highest setting, put on a foil and a stainless prop.

Performance is way better porposing is entirely eliminated. While all the adjustments helped with the porposing issue, I think the biggest thing that helped was the foil.

That being said, I think trim tabs would still help keep the bow down and planted in the waves at speed. My boat has a tendancy to jump over the waves, not drive through them. Understanding that the boat is only a 16' I think the boat should still have a better bow down characteristic at speed.

How much did it cost to install the trim tabs...if you don't mind me asking?

My 16 ran at an almost level attitude at speed. It was a very happy boat at over 4000 RPM with an Evinrude 115 and a three or four blade propeller. At slower speeds it wanted to run bow high and would fall off plane often if care was not used. The boat would plane at lower speeds with a four blade than it would with a three blade.

I think trim tabs would be most useful on the Dauntless 16, assuming the engine and propeller installation was optimal, for maintaining plane at lower speeds and for smoothing out the ride in snotty conditions.

If I had kept the boat I may have installed trim tabs, but because I seldom found it useful to run on plane at low speeds or to operate in snotty conditions, I probably would not have installed trim tabs.

TimS, I had a bunch of work done at the same time so I don't have a break out of the cost to install the tabs.

I had a 2001 16 Dauntless, and put a Tiger shark VG hydrofoil on my 90 HOnda. Immediate performance improvement: on plane in less than half the time, plane speed went from 23 mph to 17. All for about $24.00

I have a 16' Dauntless with Bennett trim tabs. At first I didn't think they would be very useful. They are great to help plane the boat at lower speed, for example when tubing small children who don't want to go very fast. They also help smooth the ride in heavy chop by keeping the bow planted, ensuring the water breaks on the V, not the flatter part of the hull.

16' BOAT
Therefore if you want the bow down while pulling tuber. snotty conditions, etc. put that "look out" person upfront and use the engine trim all the way in and the bow will be down.

A Dauntless is pretty heavy for a 16' boat. It has a 45 gallon internal fuel tank. Engine trim alone is fine at a decent speed in reasonably calm water. But at lower speed or rough water, one person up front and engine trim doesn't cut it on my boat.

EJO, would love to see what my wife would do when it is snotty and I tell her to go to the front to take a beating, LOL. I will try it.
