Fitting Trim Tabs

Job Done !

The most painful part of the whole job was moving the sounder into the hull ! once this was done it only took a few hours to fit the tabs & control panel and then run the wiring.

The tabs are very much plug and play with a couple of 2 core cables that run from the actuators through the transom into the Osprey transom boxes, then another pair of extension cabels that run up both trunks to the console all connected with Deutch Connectors. A control box sits in the console and then a control panel fitted into the top of the console controls the tabs.

Simple really just lots of measuring and drilling of holes!

Hi Chris,

Let us know how you get on with those. They're nice and quick acting and the display is good and clear.

I would have thought that the reinforced ones might be needed on an "enthusiastically" driven boat though?

I have fitted trim tabs before but not on a rib.

I have heard now there is another type of trim tab it is a metal flap that pushes vertically
into the water opposed to pressing down on it.

I have not seen any as yet but understand it looks like a flat plate fixed to the hull.

Hi Searider. Yes I looked into the reinforced ones and it was a lot of money for very little more strength unless you go up to the full racing spec ones which cost loads. I decided to have these ones strengthened myself and will be having a frame welded to the top of the tab that will make them very strong.

Looks a nice job mate,...but I wouldn't expect any less!
It will be very interesting to see how much they enhance handling!

Hopefully the photo is deceiving, but it looks like they're mounted too close to the running surface. You should always have them 1/4" to 3/8" min above bottom of boat!

I have lenco tabs with tactile switch... The trim tabs are awsome and very responsive.... The switch is possibly a little small for cold fingers or doesnt have a positive enough press.... BUT overall VERY happy.

Looks like a prototype paddle steamer

Seriously, nice job, will be interesting to hear what the effect is.

It must be the photo, i used a straight edge off the bottom of the hull when I fitted them and set them slightly over 1/4" above.
