Volvo Trim Tab kit

The QL Boat Trim System is a revolutionary patented system that uses vertical interceptor
blades rather than the conventional plates. Thanks to the water intercept
technology you get a smoother ride and more quickly onto the plane. The innovative
design is made of compo site material…easy to install, corrosion free and
virtually no maintenance is required.

… Water-force on the small blade surface creates upward pressure on the hull
bottom, thereby raising the stern and lowering the bow.

…Traditional trim system. Water-force on a large trim tab surface
creates upward pressure. Traditional trim tabs stick out from the
hull and are therefore more vulnerable and exposed to damage.

Easy installation

With its small dimensions, the QL interceptor units are easily mounted. The only affect on the hull is a small hole for the electrical connection….


…Built-in trim indication and automatic retraction

The QL Boat Trim System with built
in trim sensor, is easily operated from
the push button control panel with its
distinct trim indication (LED). Thanks to
the digital technology, the trim indicators
show the precise position of port
and starboard units. The control panel
has the following functions; bow down
and bow up, list starboard and list port.

To reduce the risk of damage and minimise marine growth, the blades are automatically retracted at engine shut off.

Low maintenance

The QL Boat Trim System is made of
composite material and all electrical
parts are “sealed for life”. It is virtually
corrosion free and will not cause any
galvanic corrosion. This means there
is very little maintenance compared
to conventional hydraulic trim tab
systems.

• Easy, safe and exact manoeuvring.

• Quick response.

• Built in trim sensor.
• Control panel with LEDs for precise
trim indication.

• Automatic retraction

• Electrical actuator, no hydraulics needed.

• Electric components are
“sealed for life”.

• Composite material, no corrosion.

• Quick and easy to install.

• Small dimensions, light weight.

• Ideal for outboard, inboard, I/O
and Volvo Penta IPS (Inboard
Performance System) and also for
waterjet installations.

• Complies with CE and ABYC

Cost?

Compatible with Merc?

Web under $600.

Works with any boat/motor/trailer until the boat gets to big for this kit. The make another kit for bigger boats.

The indicator panel ?

• Automatic retraction

So there needs to be room inside the hull at the stern?

Do you slot a big hole in the stern on each side to install it?

Yes, and its nice. Very user-friendly. The Admiral also likes it.

Answering HF or me?

Hockey Family, I did not see your post yet when I posted.

Mounts outside the transom.

Wow, Are there any pictures of the installation that also alows retracting? Does it "accordian"?

deep, it retracts into it's own body.

HERE'S A SITE that shows it pretty well.

The Blades retract inside itself, outside the transom. The housing remains. Its about, say, 2", from the transom to its outside edge.

Think of a deck of playing cards in their box, but thinner so some thick blades replace the playing cards in the box. A blade projects down to work as a trim tab per your command; retracts back into the box per your command and also when you turn the engine off.

SB, are you currently useing these?

So they don't increase the running surface, but create some drag with their lift?

Yes, I like to try new stuff that I hear good things about. In this case, I tested some before the boat was even ordered.

I liked them then. I like them now on my 330 SY Monterey.

The hole that fits the operating/wire housing that goes thru the transom looks by eye-ball to be about the size of a quarter in diameter, maybe smaller.

I don't think that I have a 70mm x 55mm space left on my helm to install the controler as there is already a in-dash fishfinder and GPS mounted in the available space. Maybe it gets mounted on the gunnel next to the throttle control?

I'm finding a price range for QL300 (15' to 24') from $550 to $750.

I have found it cheaper, but I think that a Bennett set up would be even cheaper, as Bennett can be bought without the helm station indicator. That is a extra cost feature with other brands, is my understanding, but standard with the Volvo Kit.

You want to be able to read the lights to see how far down you have your tabs with the Volvo system. So, I would want that panel in line of sight.

Buy a system without a read-out display and those perhaps could make for a happy skipper. Less info, but most likely less money, but still infinite control.

I read somewhere that because the mechanism sits at the very bottom of the transom, that drilling the hole for the electrical cable can be tricky. Seems it was a 1" (?) hole that needed to be drilled into the transom, and then met by drilling at an angle from inside the bilge area. This is all from memory.

I believe that the mounting holes are drilled INTO the transom, and not THROUGH it.

Very attractive system, nontheless. I'd like to put tabs on my boat, because it pounds in the rough stuff if everyone is seated center or aft. It will also lean if people aren't seated "just-so".

I liked the idea a lot and almost bought them when I was looking for trim tabs.

I would have done it, except that drilling that 1" hole all the way through the transom at an angle to meet with another 1" hole drilled diagonally down from inside the engine compartment is not a DIY kind of job. There is no way I could have made those holes meet correctly.

I think they need a professional to do the install.

Look at figure 15 here.

I told the Volvo guys that one of www.BoatingABC.com members said that, trooplewis, and they told me that the hole size has not been a customer issue. So, I do not know what to say. The hole looks as I said, to an eyeball look, to be about the size of a quarter.

Maybe its farther up from the bottom running surface of the boat that your understanding of inside and outside tunnel holes that match up in the middle is somewhat different than you read/think?

After reading the directions it seems to me that you do not necessarily have to drill both an outside and an inside hole, you only do that if your hole saw cannot drill all the way through. They seem very nice, and if I needed tabs these are what I would get.

In looking at Figure 15, there is a proceedure. Drill hole A (1"), then drill hole B at an angle inside the hole A through the hull, then go inside and drill hole C.
