Trim & drive Location for Top Gun
 

I just took my new 2000 Top Gun out after owning a 31 seahawk with arnesons and no bow lift. The new cig has a lot of bow lift. How should the tabs / drives be when getting on a plane and where should they be move to at cruzing and top speed?

Re: Trim & drive Location for Top Gun
 

I start with mine at 1for tabs and 0 for drives it depends on how big the waves and speed as far as when crusing but tabs usally around 4 or 5 at 60-70 and the drives at 2 maybe 3 mine is a twin step so it might be different.

Congrats on the new boat. but where are the pics?

Thanks
0 meaning down all the way to to get on a plane then moving tabs up to 4-5 then moving drives out 2-3at cruising.

Re: Trim & drive Location for Top Gun
 

Where do you have the drive at WOT or fairly close to it?

Re: Trim & drive Location for Top Gun
 

This is what i'm trying to figure out! I had the drives all the way down and a little tab about 6-7. Seemed to be to much bow lift.

Re: Trim & drive Location for Top Gun
 

?????????? :eek:

i have a 35 t/s... and its NOTHING like that

what props? spun in or out? cruise speed? WOT?

Re: Trim & drive Location for Top Gun
 

Didn't the owner you bought it from show you how to run it? He is "Shweeng" on OSO. The guy he bought it from is "Cig42X." His name is John.

Yea but it was on a lake and it was not very big. I ran it in the ocean last weekend by Myself with a lot of chop. The boat I'm use to has no bow lift at all. I just need a little direction thats all.

Re: Trim & drive Location for Top Gun
 

If the boat porpoises a lot I wouldn't run a lot of trim and keep the tabs around even when cruising, this will give you minimum bow lift. When running WOT I would trim it to 5-6 and lift the tabs up. A good idea would be when the boat is on the trailer mark on the indicators where neutral and even are with the drives and tabs compared to the bottom of the boat. Hope this helps.

Re: Trim & drive Location for Top Gun
 

Thank you. I have marked the indicators. The only thing I'm not understanding is when you refer to "even" is that even with the angle of the hull (because the tab is mounted 1" above the bottom of the hull) or pushed down so the trailing edge is even with the bottom of the hull.

Re: Trim & drive Location for Top Gun
 

In my 1997 straight bottom Kevlar Gun I plane out with drives in all the way or at negative trim zero on a Bravo drive. With my tabs down @ 7 she pops right out of the water at 35mph or so @ 2800 to 3000 rpms .
We don't run to much positive trim 1 1/2 or 2 maybe until the low 70s @ 4500 rpms or so and unless its real real choppy we still run some tab to keep her tight depending on conditions.
After the mid 70s these hulls really come alive and want to be trimmed out and loose the tab.

Good luck with the new rig, your going to love it.!

Re: Trim & drive Location for Top Gun
 

That is just what I was looking for.

Thanks WildWarrior

Re: Trim & drive Location for Top Gun

Re: Trim & drive Location for Top Gun
 

Thanks Stormrider can you get me the dyno sheets or any other history on the motors. I spoke with Jeff about 2 weeks a go but did not see anything yet.

Thanks, Phil ph: 714 241 3600 fax: 714 241 3601

Phil, keep trying Jeff, he's been pretty busy lately.

What exhaust are you using? How does she sound and idle?

Re: Trim & drive Location for Top Gun
 

CMI cracklin good very little surge. It's funny you ask about exhaust because i was wondering why one moter has platmum e-tops and the other has ploished?

Re: Trim & drive Location for Top Gun
 

Nice to see that the big bird will be staying in so cal!! congrats!!

Re: Trim & drive Location for Top Gun
 

When you do get a hold of jeff, ask his opinion on CMI.

Re: Trim & drive Location for Top Gun
 

Thanks Greg

Now Seahawk aka Big Bird and still S.C.O.P.E.

Re: Trim & drive Location for Top Gun
 

props are 28
spin out
the fastest i have gone is 84

were do you set your drive and tabs?

Re: Trim & drive Location for Top Gun
 

5 blades spining in... no tabs... trim out to 7

Re: Trim & drive Location for Top Gun
 

I don't think i have ever run the drives at 7, it slows when i go past 3.5 but i will try next time but i also have 4 blade props.
what speed do you get?
also the most rpm i get is 5100
