I was told they experience better planing, lower plane speed and better performance.

Yes sir,
My interest was stimulated after I was running and saw a similar boat as yours. When I asked the boater what was the purpose; they explained the increased stability and power increase.
I used to have a cuddly cabby converted to sea-drive. It was similar and needed to mount the engine. I was exploring the idea, improvements and benefits of this mount and what are the drawbacks?

? Do you have a helix 9 also?

Would you take 500$
I was about to pull the trigger on the helix 5, but would rather give you the money!

One more thing; that little trimmer zinc anode May also need adjusting.
Also for Dan Pearson; What is your top speed? Is it 50+mph.
I would not be surprised if it was (60) sixty.

Phillip and group,
Having owned various boats(12’Carolina Skiff, 16’ Ashcroft center console, 20’Starweld 20DC, and several others; just wanted to share my experiences.
There are different types of hulls, bay boats, flat bottom , deep-v, displacement, and many tri-hull variations. When you have a reverse chine
Type hull, the boat will plane out and ride dry. However it is sensitive to balance. Fore and aft and side to side. The North style all-species boat are an all around compromise. When I used to use different boats I noticed list, caused by uneven loading and planing at high speeds. Every boat I have ever been on has some list from time to time. After experiencing it , I investigated corrections. Every good independent boat man I have ever spoken with , gave me the same advice. Install the hydrofoil on waterline anti-cavitation plate. The brand I always use is stingray. I know you will believe otherwise, but a small amount of lift/pressure exerted on a balanced object, will effect the balanced object. A greater pressure exerted on the same balanced object closer to the balance point, neutral point will be required for the same effect.
If you install a stinger model , I guarantee you will be amazed.
Not only will you not propose, if will not dig in on launch to plane. Also, it will plane at a slower speed. (16-19mph) My boat is fully rigged
(Three batteries,two anchors, tool kit, safety kit, 7 flotation devices, three paddles, two boat hooks, two nets, 45 quart cooler, and miscellaneous electronics, fish finders, vhf radio, Bimini top , 150 hp f150xb long foot Yamaha 4stroke and 35gal tank. Before I tuned the boat it was ok , but I noticed some stability issues. I went to Walmart and bought my stinger by sting ray hydrofoil. 4 secs to perfect plane and extremely stable.
If you invest in trim tabs , know that when properly adjusted they will cut 3-5mph off you cruise speed. Proper means leveled out.
They have to be level with the bottom. If you hang an outboard 36 inches on one side , that must be balanced. Sounds reasonable. The boat is balanced. Some additional feature unbalanced it. They are cargo, engines, people, gear and live wells , coolers and obviously batteries and trolling motors. Don’t be surprised that some rigs need trim tabs and hydrofoils.
Just my experience with 53years of boating.
