Wanted to start a thread on this. I want to improve the ride where I can. I recently added a Permatrim and want to now upgrade the Lenco 12w x 12L tabs. Wanted to see the feedback and tips on this upgrade. Don't want to remove the original brackets/hinges and SS screws from the transom if I can avoid it.

Questions:

1). Can you replace the tabs without replacing the original 12" wide hinge brackets

2). Can u reuse the original actuators or do you u have to replace the actuators to a longer shaft to match the longer tab plates?

3). Will you gain a significant improvement in bow control with 18" (or 24") tabs?

I'm sure there is plenty of good experiences opinion on this.

Thanks.

I have had the 12x18 installed on my 2320. I’m still using the actuators from the factory installed trim tabs (12x12).

The 12x18 were installed over the winter and I plan on testing them out this week. The new 12x18 are drop fin Bennett’s. My boat is a 2016 FYI.

I’ll report back after I run the boat.

I installed 12x24 tabs when I had a Parker 2310. They made a big improvement in controlling side to side and bow rise with using very little tab. It’s a simple job to do it right by moving the actuators over and then filling the holes with marinetex.
I recently upgraded my tabs to 12x18 on my 2510, I could only do an 18” span with twin engines. Made a nice improvement, but not as considerable as the 24” span on the 2310.
I also had permatrims on both boats.

Great feedback. Id be curios to know if the changes made are to length or width? Did you change to 18" wide or 18" long. If you had to move the actuator I am assuming it's 18" wide?

Hey Guy. I think you are on the correct path. Give me a call to discuss all the options that might help your ride.

You want to go wider on the trim tabs. Go to "Classic Parker " forum and do a search, lots of really good info of trim tabs upgrades for parkers

Been out of commission with a muscle spasm in my back. I took these today. No plans for sea trail yet until my back gets better.

I have a 2018 2320 pilothouse w/ 300hp -- I'm running a stock prop and no Permatrim. I swapped out the smaller stock trim tabs for the 12.5"x18" and added a 3/4" starboard block to the hydraulic.

Ride improved significantly and I don't need to dig my tabs as hard under load. I trim the engine up 2-3 bars without touching the trim tabs and get 2-2.5mpg consistently on a normal day. Highly recommend installing the larger tabs, call the boys at West Coast Marine and they will dial you in.

Thank you. This was a good call. I did not replace the original 12x12 tabs with new ones. I installed the Permatrim and the tab blocks (I used two 1/2" blocks on each tab so I could back half out if it was too much on one side - i.e. starboard). I am also running the original 3 blade prop.


What a HUGE comfort difference. The Permitrim + tab block combination is great! Can run hard into the chop with the front end down and keep my teeth and lower back intact. Considerably more tab range now (drive and lift) on both sides with the slightest touch of the tab control switch.


Note: Comfort though comes at a cost. I did 161 nm this weekend chasing those blue devil fish, so I have a good economy read. I have a 2007 with a similar year F250 and a belly loop and bench seat on the roof - with 4 guys, tackle, ice, 150 gal fuel, and a 65gal bait tank, I burnt 113 gal of fuel and achieved an average 1.42 nmpg (1.63 mpg) in excellent sea conditions. On plane she runs at 28-31 mph (4800 rpm) getting 2.1 nmpg (2.415 mpg). But off plane out of the hole to mid (0-19mph) pushing all that weight she sucks the fuel.


I am going to try a 4-blade prop and a different pitch to try and get a better bite and better low-end torque so maybe my average mpg will improve. I know I will lose top end performance, but I don’t run the boat WOT and am more interested in better performance out of the hole and through the mid-range.

Do under mount, it takes the load of the bolts so all the load is transferred to the cavitation plate and I think it’s designed for under mount.
