It is indeed a "timed event". No mater if the Tabs are all the way down, or all the way up the system will run will run about that long to insure they are fully retracted. Tom McGow Bennett Marine

I'd have to see pictures of the transom, we make a bunch of custom Trim Tabs for Grady. Tom Bennett Marine

Below you will find basic troubleshooting. Do step 3 and let me know what you find. Also here is a link to our video library, there is a troubleshooting section https://bennetttrimtabs.com/tech-help/video-library/ Tom McGow Bennett Marine Fluid: Automatic Transmission Fluid (ATF) any type...

I'm still around! Sounds like you are going to get the Trim Planes you need. Anodes are really important! My rule of thumb is if the boat is in the water long enough to need bottom paint, the tabs need anodes! Plus they are cheap insurance if you happen to run across a "hot" dock in a...

You may be correct regarding the retrator. The EIC5000 as slightly different troubleshooting, it can be found in the owners / install manual. Here is a link to it https://bennetttrimtabs.com/EIC5000-Install Tom

The system operates at 350 psi normally but can greatly exceed that when running the boat i.e. coming down off a wave. I have seen compression fitting splices used successfully. But I would like likely replace the tubing if it were my boat. Tom McGow Bennett Marine

Try calibrating it and make sure to "firmly" press the sun and moon buttons at the same time. Tom Bennett Marine

They should operate as the Tabs are being moved (but run the Tabs longer that it takes for the lights to go all the way down and up). How old is your system? Tom Bennett Marine

Here are calibration instructions. Let me know if you have any questions. Tom McGow Bennett Marine Start with both Trim Tabs in he full up position 1. The port and starboard red LEDs will flash alternately, indicating that the system is not calibrated. 2. Press and hold the sun and moon...

Use any type of Automatic Transmission Fluid (ATF). Don’t worry about the exact brand or type – it will all work, and can even be mixed. To add fluid, remove the Lexan cover on the HPU, locate the “filler stack” in the left front corner of the reservoir. There is a round plug sealing the filler...

Since I work for Bennett I'm biased! But I would suggest looking into the 912ED 9 x 12 Edge Mount Tabs, here is a drawing to give you an idea how they would fit: 912ED The vertical clearance is approximate since it will change a bit due to transom angles. Let me know if you have any...

Hello Kyle, As I suspected those are "short" actuators, and both the Bennett and Lenco electric actuator conversion kits will not fit in the pockets. I would suggest replacing the O-rings in them. The solenoid valves usually fail completely, not intermittently. So it's more likely a...

Bennett makes a retrofit kit for our electric BOLT Trim Tabs. They have a lifetime warranty on the actuators. But it really depends on the Tabs that were fitted to your particular model Grady. We make lots of custom Tabs and actuators for Grady and don't always know what ones are on any model...

Probably Bennett, Here is a link to our video page http://www.bennetttrimtabs.com/tech-help/video-library/ at the bottom of it are all of our troubleshooting videos. Here is a link to the motor making noise and no tab movement https://www.youtube.com/watch?v=wd2RjZ63tTI Below you will find...

Until you get in to speeds of 11 to 13 or more the trim tabs are really not going to have any affect on the boat's attitude. We have seen some semi displacement fast trawlers benefit from really long span (side to side) Tabs at speeds as low as about 11, but the tabs were huge. 42" x 12" on a...

The 10 x 12 M120 Sport Tab would be a good choice, its shorter actuators take up less transom height, good for the future platform. We recommend them for up to 23 ft boats. Tom McGow Bennett Marine

This is the first thing I would look into. Scratching my head too! Tom McGow Bennett Marine

Thanks Seasick! I am well and still cruising the boards! I really like our new electric system, but the M120 is still one of my favorites. The HPU (pump) should be mounted in an area that does not get really wet, some moisture is OK. I had a set of the M120s on my old Aquasport 20 foot...

Bennett also makes electric Trim Tabs nowadays. More info here Bennett BOLT Electric Trim Tabs http://www.bennetttrimtabs.com/bolt/ If the boat is kept in saltwater hydraulic systems can be preferable. But the actuators on both our electric and hydraulic systems have a lifetime warranty. Tom...

Run Forest Run :) Those are a mix of parts, small trim planes that were custom made for a small boat builder to mount in a pocket, note the mounting holes for the actuators are offset, combined with mismatched Hinge Plates that are way too wide (the Tabs will move around in them) and the...
