Here is a hydrofoil for your consideration in the future. I have one on my Boston Whaler 22' ........ I just ordered another one for my dory because they have changed the design since my last one. ..........I will let you all know how I like the performance on the Dory when I get it installed and sea trialed.

Mike, I'm anxious to hear how this works out for you. I am considering Lenco Trim tabs, but thought I'm try some kind of engine trip plate first (less cost) to see if that'll get my stern up a little more. I don't seem to be able to raise or lower the bow much just using the engine tilt... Thanks

If I had to vote, I'd take the Wallas first. I use it a lot more often than trim tabs. I think I could transfer enough weight from side to side and fore and aft to compensate for the engine trim couldn't take care of.

See you Friday night or Saturday morning. Jackaloff Bay?

Perhaps a different "take" on your dilemma......get the Trim Tabs now, then when it gets chilly, the spousal unit will insist on a Wallas Heater....thereby creating a "win, win" situation. :wink
 
I sold my trim tabs and was wanting some feedback on the permatrim ...lol... I didn't think it would turn into another trim tab thread. we have several of those already.
 
I got my new hydrofoil installed yesterday and took it for a short spin with Jim (Duck) and another friend aboard. Since I was replacing an old plastic (rubber) doe fin, I did not see a dramatic difference in "hole shot" but where I did see and feel the difference was in steering response at slow speed (docking). I have Bennet Trim tabs as well and wishing for this feature more then anything else.

For 39.95 plus shipping I am more then pleased with the setup.

I put the Permatrim tabs on the end of last year. I have a 24ft TomCat. I was basically trying to get the whole boat out of the water more. I would say they do work but in adjusting trim you need to watch or you could have water fly all over the engines or shoot a rooster tail out 20 or 30 yards behind the boat. (looks kinda cool!) I assume thats good. My boat should be in Lake Champlain early next week!!!!!

Roger on Sensi..... did you ever install the Permatrim Hydrofoil???? I'm still undecided on them or possible the one the one WhalerGoFar installed. His test report was not conclusive enough for me. How about someone posting the dimensions on both. My thinking is that the Permatrim would do the job of lifting the stern just a well as seperate trim tabs. On a deep V seperate trim tabs are the way to go because of the need to level the boat port to starboard as well as lift the stern. (Had them on a previous 27' deep V) Roger since you have the Permatrim, could you measure them for me, also you too, Mike on WalerGoFar. Also for both, do they come predrilled or do you have to drill them. That could be difficult on the Permatrim's since they look like stainless.

Thanks for any and all input on these two Hydrofoil's
 
hey there Roger on the Fran Sea

I have not had a chance to install the permatrim yet. I am just finaly taking her out for the maiden 2006 excursion. I just got all the wiring and motor reinstalled last night, after a visit to the factory for some tender care from the experts there.
We will take her out tomorrow for some shrimping and then I will try to get to installing the permatrim next week.

I havn't opened the package yet to see if they are predrilled or not. It won't be much of a problem if not. I have a good slow speed drill press in my shop and I drill stainless all the time.
 
Fran Sea: You should find the Perma trim already drilled. It is just a matter of clamping into the position you want, mark the holes with a marker and drill. Add some sealant and bolt on. Make sure your drill will fit above the holes closest to the stern of the boat. On some engines there is a small casting that sticks out about a foot above the anti-cavitation plate. This may restrict your drill from fitting above where you need to drill the last hole on each side.

You can check thru the photo section and see several perma-trims mounted on variouse engines. You can check my album, too. For some reason the photo section doesen't seem to be available right now.

You should notice that the Perma-trim is "HUGE" compared to the one a few post's up (Bobs Machine?) That one is barely any bigger than the anti-cavitation plate that it is mounted on. The bigger the trim plate the more lift and the more cost for material to make it. The Perma-Trim is first class in quality, fit, finish and color to match your outboard.

Chris, I may have to agree with you on the larger size tab giving more lift, but it would only matter to me if I were in an airplane, but since I only want to lift the back of a boat 4 to 6 inches I don't think "Huge" counts here. Besides the outboard mfg's didn't even find it importaint to add more then 2" of plate.

Maybe if we all added spoilers on the front of the boat, it would keep the bow down and save us from adding trim tabs.
 
Chris on C-Weed, thanks for the info. That was my concern, that the one's from Bob's Machine seem small and I thought it would be important to get more surface so as to have more control; consider that a pair of 9X12 trim tabs give you 108 sq inches. I've seen some boat with rather large "plastic" wings bolted one each side, but these are curve toward the stern and I felt they might contribute to porposing. I'm inclined to go with the "Permatrim" but think I will hold off until I get back from the Chesapeake Gathering as I may get some feed back there, and possibly even see one installed..... thanks for your input; but still interested in getting actual measurements on both.... :bat
 
The Permatrim is aluminum and only has the back two holes pre-drilled.

I have a NIB Permatrim, model 1 in Grey sitting in my garage. My trim tabs are sufficient. Anyone needs the Model 1 (I know it fits Yamaha 75 and 90 hp models but don't know what else) let me know and I'll ship it for 1/2 the current price plus shipping.

PM me if interested or sneaks(at)mail.com

Fran Sea: Perma Trim is 12.5" wide not including the turned down sides and 22" long.

WhalerGoFar: Spoilers on the front of the boat would work but at C-Dory speeds they would have to be "HUGE".
 
Just put my new permatrim on the 60 Etec this week. First run at speed was this morning (btw the one for my motor is 11.25 x 18) Biiiiiig difference. All but eliminated the tendency of the bow to point skyward when going on plane. The boat seemed to almost rise on a level attitude til it was on plane. I had been using an extra cushion on the seat to see over the bow. Did not need it today. Also much softer ride in the chop with the bow slicing instead of bouncing along. I'm very happy!

Just spent the last weekend on "cool change" since I installed BOB"s Hydro plate. Very happy with it, brings the bow down VERY WELL when called for, all I need. Also steering is improved.

TWO Thumbs up!
