I recently purchased a 21 WALKAROUND with a Mercury 200-HP EFI two-stroke. It rides very heavy in the stern. I think trim tabs may be a necessity. What size trim tabs are recommended? Are there any other options? Thank you.

Check out the current discussion on this topic, I think it will answer your question.

Good luck with the new boat.

gqwhaler,

Welcome to the forum and congratulations on the 21' Walkaround...fantastic boat!

Trim tabs are definitely necessary on the 21. Go with the Bennett or Lenco 12"x12" tabs. You will be amazed at how much faster the boat will plane and cut through chop.

What year is your 21? Check my profile.

Steve, do you use a dole fin on the cavitation plate? Will this help? My boat is a 1992 with a 2000 motor. I saw the pictures of your boat--very nice. Where did you have the arch built? How costly was that?

I put 9x12's on mine along time ago.. Made all the difference it the world... specialy when I have a few big guys standing in the back. I do find myself running with them all the way down all the time.. thiking maybe they sould have been bigger ?

It's a great boat... you'll love it..

Billy,

I've had a Doel-Fin on the outboard for the last 10 years or so. Took it off last year when I installed a new prop and am still evaluating whether I need it or not. The Doel-Fin will definitely help in getting on plane and being able to stay on plane at lower speeds as will the trim tabs.

The biggest performance improvement I have noticed (besides the trim tabs) was the new Mercury 4-blade Offshore/Vensura prop. Fantastic holding and acceleration.

The arch was made by Lakeside Marine in Lakeside, Ohio (Lake Erie) back in 1993. Believe it was around $2500.
