Re: Whale tail stabilizer slowing me down here
now put a set of Nauticus Smart Tabs on it for $100. you will really be surprized.

I have one on my 18' Celebrity I/O with a 4.3L V-6. It really was a big help with my boat but I did lose 3 or 4 mph on top end.
Re: Whale tail stabilizer slowing me down [links]
If the motor is tucked in rather straight down or in the begining stages of trimming up, it can cause tremendous drag. [links]

Re: What does a whale tail do?
"If" your boat can use one, it still needs to be setup correctly or you may experience some the negative effects they may cause. more
If the effect is anything like my 16 footer, when i removed mine and laid a little gas to her the bow stood up so high i couldnt see of it. Also i had to go quite a bit faster to get on plane and to stay on plane. I think its was around 22 MPH. Didnt really have time to look as i had to stand up to see over the bow. I will also add that the comming off plane quickly will cause the wave to come over the stern into the motor well. I had to watch it and adjust my speed accrodingly when slowing down.
With the tail on i can plane at around 12 to 13 MPH And i can see over the bow all the time. No problems coming off plane and it handles alot better.
Should you add foils purely to get a speed boost? Probably not. Although there are a lot of claims – mostly by the foil manufacturers – of speed boosts, in my experience if there isn’t another performance problem the foils solve (like the trim issues) then speed remains the same. [links]
Adding a hydrofoil to an outboard does provide a performance boost much of the time. The smaller the boat the more significant the impact is, especially on boats that don’t have trim tabs. On a 16 footer with a mid-sized outboard and no tabs, for example, a hydrofoil will usually level out the ride by forcing the stern up and the bow down, and will end or greatly reduce porposing. There is a performance boost, usually of two or three MPH at cruise, as a side-effect. In other cases, specifically with powercats, foils will reduce the side to side rocking motion that often accompanies a beam sea. The picture you see here is of my own boat, a 22 Glacier Bay. When I added the foils side to side motion dropped in the 10 to 15 percent range. What about a performance boost? No dice; in this case speed remained identical to foil-free operation.
On a cat, hydrofoils can reduce side to side rocking while cruising. here
Will adding a hydrofoil improve the performance of your boat? I get asked this question all the time, usually by people who have outboard powered boats with relatively lackluster performance. And I always start my answer by cautioning that every boat is different, and there are no guarantees. That said… Adding a hydrofoil to an outboard [. ] more

Of course, many people want to give a foil a try but hesitate, because it means drilling holes in the anti-ventilation plate. But check out Sport Marine’s SE Clip, which allows you to mount Sport’s hydrfoils without drilling. It seems impossible that these clips can actually take the torque and hang on to the lower unit without any drilling, but I tried ‘em on the Glacier Bay and both have held on tight without a problem. One caution: the installation instructions seem to have been written by a chimp, and you’ll feel like Bobo yourself when you try to put these things on. It took me a solid three hours to figure out how to do a 15-minute job. Meanwhile, if you’re confident the hydrofoil is a must-have, traditional drill-and-bolts like those from Dolcher and Stingray work quite well. So back to the question – should you put one on your boat? Only if there’s a problem like those mentioned above which you’re trying to solve. If your boat already performs well, however, you shouldn’t expect these things to work magic. more
And, Welcome to the forum. Both of ya..
i was just curious as too how much if any i should expect it to lift the nose. but after my trial and error testing i figured it just rode at pretty much a level stance no matter what. as i stated i never had a pontoon and was always used to gettin up on plane then trimming it out on the ski boat. i know pontoons have different characteristics. here
The Enertia holds the water much better than the Black Max did. A LOT. The Black Max ventilated on me with even the slightest trim out from the transom. The Enertia is totally different. Not sure if that has anything to do with the whale tail, but I'm guessing it does. [links]
