My first post so please forgive me if this information is posted elsewhere. I have a Dauntless 15 with a 60 hp Johnson. On my first cruise I noticed the boat was very susceptible to porpoising when changing speeds or power setting. Yes, it can be trimmed to alleviate the problem, but with a slight degradation in speed at the same power setting. Yes, I know that load distribution will affect this problem. I saw a product on Shipshape TV that is ABSOLUTELY the best item I have installed on a Whaler. It solves the porpoising problem for good and adds about 3 mph higher top speed. Before I mention the name, please understand I am not specifically advertising this product, but trying to help fellow Whaler owners enjoy their boat more. Having said that, the product is Smart Tabs. I put the 40# on my boat. All the difference in the world. Made my boat handle like a 17'. Great for increased lateral stability, too. If you have a very fast V hull boat, these will eliminate chine walk at high speeds, too.

Smart tabs are easy to install. Just remember that the farther out from centerline on the transom you put them, the greater their influence on lateral stability is. FORGET motor mounted "Whale tails". Although they will give you slightly better out of the hole jump, they also give you higher drag and a loss in top speed. Since they are on the centerline, their influence on lateral stability is minimal. Smart tabs allow you to trim your engine for almost 0 thrust angle = 100% forward thrust hence higher top speed. These are simply transom shock absorbers, and they make your ride on plane in rough water much smoother. Coming out of the hole - right now and stay on plane at a slower speed. Are they adjustable from the helm - no. Do they need to be - no. You adjust them per the instructions when installed. Fine tune the adjustment once in the water and you are set. Are they better than trimable tabs? I believe so since they absorb shocks unlike adjustables that are fixed in a selected position until moved again.

Smart tabs are much cheaper than adjustables. No wires, no cables, no hydraulic lines, no control panel. What about warranty? Okay, I had a small rip in one of my two year old cylinder boots. Called Nauticus, told them the problem and that I wanted another boot. No deal they said. They just sent me TWO NEW Cylinders for FREE!!! How is that for warranty?

I've put a set on a 9' Avon, and a 21' Caravelle (300 hp, 60+ mph boat) in addition to my Dauntless 15. No complaints or problems. Check them out. If you put them on you will be satisfied. Let us know.
