OUTLAW EAGLE MANUFACTURING

[mountainman]

I bought a 16' Lynx this summer and with the rear tank full running off the bow tank at full throttle it likes to porpuse on me it can be a real pain the but. I have turned the trim tabs down just a little bit and it hasn't really solved the problem. Besides running only the bow tank (which isn't really an option) what would you guys suggest to help rectify the problem. Oh and I'm running a 240SJ. I run the Wapiti river by G.P. and it gets pretty skinny in spots so I don't want to turn the tabs down more then absolutely necessary. Also I'm fairly new to this as it is my first boat.

Moutainman, there are allot of questions we need answered, What year the boat is, what the hull degree is, If the skid plate around the pump has a piece cut out, how far the trim tabs are turned down, is it a dog box model or flush rear deck, It is probably easier to call and go over all the questions you have for the porpuse problem you are having.

[mountainman]

Well I'll try and give the info I know.
Its a 2005 16' Tuchodi special with an 8 degree hull its got the doghouse the trim tabs are turned down approx. 1/4" not sure if the skid plate is notched or not. If we can't figure it out on here I will give you a call when I can get the rest of the info.

Any updates on this topic. I have the exact same boat and it porpoises under full throttle also.

Hey guys..does it matter if you are going with or against current.
I find most utility boats will porpoise going against the current if they don't have trim tabs or a HPD

[T-REX]

It doesn't matter which way I'm going, it acts the same.

we have a 18ft bobcat that did the same thing when we got it best way is just adjust the trim tabs down a crank or two try it , if it still does it,repeat until you have it corrected also the more weight you have in the back the more pronounced it is we always burn the back tank first ,and when we added a kicker on the back I had to re-adjust things a little.
and as far as the trim tabs hanging down in skinny water it actually seems to lift the back end out of the water a little more when on step the nose seems to scrape bottom before the trim tabs do

Mountainman, my 16'Lynx acted the same as Bender's. Bending the tabs down more should help.

Gentlemen,
Your dealer or Outlaw themselves, can send you a 3 degree wedge that will help your sportjet. Wedge your nozzle down, pull your tabs up. Worked for me. There is also some ride plate updates you can do, ask Ken at Northgate, he can supply you with a couple different options. If you keep lowering your tabs, soon you will be bending the turn buckles. They are around $80 each! A wedge is approx. $50.00.

Thanks for the info guys! Been out of the country for a couple of weeks and now back to work. With this weather all I want to do is go boating not working. If I can find the time betweenboating and working I'll get this fixed it is a bother but keeps me off the throttle abit

[T-REX]

I got mine to stop porpoising. I had the wedge in before but not the plate behind the jet intake. I welded it back in at a slight angle and lowered the tabs 1/4". It made a big difference. Not sure if it was the plate or the tabs, or maybe both.

[mountainman]

I talked to the guys at Northgate and checked out my boat a bit better. Seems I don't have the piece cut out of the skid plate. I turned down the trim tabs a bit more and that seemed to help quite a bit but it still does porpoise some what. How far can a guy turn down the tabs without fear of bending the buckles and such? Or would the wedge be a better way to go?
