Repowering the Bigobass 25 Talon SKULL BOAT!

[WILDMAN]

Bigobass just could'nt get by with a 94 mph boat, so he decided to repower with 300 Promaxes. This was the "Skull boat" that was for sale last year out of Canada. It had 225 Promaxes. I sold him a pair of 300's off a 25 Liberator I have. The Liberator will get 300X motors or new 300XS motors. Here's some pics of the swap.

Here's what it looked like before

Motors are on and ready to be hooked up

Cool looking boat. Are those skills gelcoat, paint, or vynal?

[WILDMAN]

All the graphics are in vinyl.

[bigobass1]

I'm bringing the 34's,lets see what it will do :reddevil:

[jeffbare]

Keep us updated on the performance. Looks good.

[Chummy]

Oh thats where the boat with no center pod went!!! I was wondering... interested to see how fast she is

[Ospreyproduction]

Perfect!!! As soon as he gets a boat dialed in, he sells it. We'll be looking for the listing in the for sale ads. We want that Talon here on Lake Murray.

[WILDMAN]

The motors are all hooked up and running. I'm just waiting for the new Marine Machine wingplates. The motors will also get custom matching cowl decals.

[stokernick]

Randy,does that diamond plate stand extend and retract into the trailer bed?

[WILDMAN]

No, it's fixed. Sure makes it easier to work on the motors!

[stokernick]

No doubt,but now it's got me thinking a slide out ramp might be just the s--ts!

[Corona Mike]

Nice as usual Randy!!:cheers:

[imq707s]

What kind of speeds will the 300's get him?

[RNM018]

Isn't Lee's Talon CC a 25' also ? I notice they do not share the same bottom .

Rich Martin 018 :confused:

[Pro300x24LD]

that is a bad bad boat

[WILDMAN]

It should run at least 110 with these motors. The bottom is different because this is the only one made with no centerpod. I was told it was originally Talons factory race boat.

[bigobass1]

Randy,motors look a little small on it.Let's put 3 :D

[WILDMAN]

I'm gonna test drive it for ya till the skulls peel off!

[150aintenuff]

hang 4 on it just to see if the hull will stay on the water...

[Jetboat Jared]

we will need vid of it running you know that right

[Ospreyproduction]

Randy,motors look a little small on it.Let's put 3 :D

Perfect. Now I won't have to add another when you sell it!

[MODVP22]

It should run at least 110 with these motors. The bottom is different because this is the only one made with no centerpod. I was told it was originally Talons factory race boat.

If that's true then this was Eric Saloom's (Allison7710) old boat.

[WILDMAN]

Finally got the wingplates today. We put them on and took the Talon out for a spin. There was a problem with the trim so we could'nt get the max out of it. You can see how flat the rooster is at speed. The boat handles great and still ran 102. I'll let Brad do the highspeed testing. Here's a video and some pics

OR WE COULD GO THIS ROUTE

YOUR CALL:leaving:

[WILDMAN]

Well, I did'nt have the video on the entire time we drove it!

[99fxst99]

Props turning inboard?? Does it need the bow lift?

[baja200merk]

the pictured v6 would have a much better power to weight ratio :reddevil:

i guess i should try to go to bed now.... :leaving:

gotta make sure i tied the pontoon boat to the dock :o
kid :D

[150aintenuff]

they turned in before, so I assume randy was just seting it up as it had been before

[Skatin]

Awesome looking Talon.

I had mine turning in for a while but I didn't gain any speed and I didn't like the way it handled. "When I had 2 on it".

[AirRide]

Did you video that on Lake Kerr?

[WILDMAN]

They turned in before, so I did it the same. Turning in helps with the porpoise. This boat is a full tunnel, so it hops more.
Skatin, how fast did yours run when you had two STOCK 300's? What props?
The video was taken on my little "Test Lake" Lake Ashby, west of New Symrna off RT 415.

[bigobass1]

Randy,is that triple setup cool or what?:D

[Pro300x24LD]

http://i158.photobucket.com/albums/t117/Randycorson/100_2188.jpg

I don't understand the point of those "spacer bars" being bolted in place right against hte wingplate, seems it would place less stress on the bolts to have them above the spacers and rams/tiebars, instead of below just acting like a washer. It would seem to reduce the leverage on the bolts and also put them in a double sheer situation instead of single sheer, but I've never seen a setup like that before so I don't know.

[Powerplay25]

Good stuff. Can't wait till you get it dialed in.

[WILDMAN]

They are Marine Machine, so I'm sure they've done their homework. I'd imagine they are that way because they have had occasions where the "ear" may bend under extreme conditions. They retail for $895 each!

Not doubting just surprised. If you were to take that peice and flip it around and bolt it over the ram and over the tie bar i would think it would add a lot more strength. Single shear bolts on steering parts scares me (my own boat included)

[WILDMAN]

I see what you mean now. You're probably right. Maybe I'll change them tommorrow. They came with no instructions

[Pro300x24LD]

I see what you mean now. You're probably right. Maybe I'll change them tommorrow. They came with no instructions:thumbsup: Let us know if it works out better that way.

I can't get over that boat though, I love it!!!:D

[tux974]

Randy,
This is correct and that is the way they should go. Like mentioned above it will spread the sheer load.
Boat looks great :thumbsup:

The video was taken on my little "Test Lake" Lake Ashby, west of New Symrna off RT 415.

When I first got the boat it would run around 108-109mph. Props were 15X34 labbed Merc's. After motor mods 116mph same props. I tried several prop shops and the Merc's and BBlades were by far the best.

What did you get out of it after the 3rd one was added?

Brad has a set of 34"x15" labbed Merc 3 blade cleavers for it. What was your setback and motor hieght? What kind of motor mods?

[Skatin]

What did you get out of it after the 3rd one was added?

I got a boat that will sit on the rev limiters in the low 120's.

[Skatin]

5.5" setback 2.5" above. Simon motors with a little more compression than normal and I mix Av gas.

[bigobass1]

This one is set at 1.5 inch above right now.Randy say's it's turning a set of 32's he has at 6000.Not sure it will turn the 34's but might send out the boxes to reset the limiters to 7000 and bump up the motors at bit higher

[150aintenuff]

even with the stock boxes you may want to go up... 6K is verging on abit low for the x motors.... lookin good tho..

[150aintenuff]

time for 36's

[whipper]

Great job guys! Youll have her screaming and flying in know time.:thumbsup: I love how that hardware looks on the motors. Heavy duty! when I saw this boat forsale I couldnt believe the deal you guys got! Well worth the long trip to pick her up. Love the Sculls to.:thumbsup: Cant wait to see the video when shes dialed in.

[Skatin]

even with the stock boxes you may want to go up... 6K is verging on abit low for the x motors.... lookin good tho..

Them there aint X motors.

[Skatin]

time for 36's

Nope. Got a whole new direction.

Top secret stuff here!!!!

[150aintenuff]

Them there aint X motors.

I stand corrected... I saw the X cowlings and grafix.. my mistake..

[Skatin]

6k is a little low. Raise em up and check the toe.

What is the history on the boat? How heavy is it?

There is a 25 around here that used to be an old race boat that is heavy and runs 99mph with stock 300's. It has a center pod though.

[WILDMAN]

You guys were right, I had the wingplates on wrong. The motors are 98-99 300 promaxes.

http://i158.photobucket.com/albums/t117/Randycorson/100_2248.jpg

[Skatin]

Never seen a wing plate like that. Mikey likes it!!!:cheers:

[WILDMAN]

It's Marine Machine

[baja200merk]

much better :thumbsup:

[Chummy]

now go run it again with some new wheels

[150aintenuff]

now go run it again with some new wheels

and taller engine height

[WILDMAN]

I just ran it to make sure everything ran right. I'll let Brad mess with the setup. I don't want to have anything blow up if the motors are too high while I'm driving it. It's an easy boat to drive though!

[Skatin]

My Talon is a lot easier to drive than my Skater was.

If go out in big water you might want to add a little weight up front.

:thumbsup:That looks SO much safer and stronger as far as the bolts are concerned :thumbsup:

I love this boat more everytime I open this thread up.

[WILDMAN]

Finally got the motor decals today. It's hard to see, but they are metallic maroon and pearl white to match the other graphics.

Did you run it yet ?

[WILDMAN]

Yes. Go to post 23

[imq707s]

Man, that is such a clean looking boat.....everything about it looks amazing!

Nice Job! :thumbsup:

[fast fun 2]

No pod, I like it :cheers:

[DoktorC]

How much setback did you use?? Is that the optimal amount?

[WILDMAN]

It has 7.5". I have no idea what is best.

[DoktorC]

It has 7.5". I have no idea what is best.

Perfect lol. I've got a buddy that needs jackplates and wants to go 300's in the near future...

[WILDMAN]

Bigobass came to pick up his Talon today. We went for a test ride and made a few changes. It smoked a while at first because he still had oil in the gas from the 225 Promaxes. We will go on a 100+ mile run tommorrow on the St Johns River. Here's some pics. I'm gonna download a video later.

man that boat is quiet

[Peter J]

But some has to do it!! Randy you must hate going to work every morning.Another fantastic boat!!! Peter.

[whipper]

Hands off the wheel at 100!:D:thumbsup: Looks like you need to go up a pitch or two? Sweet set up!

[Skatin]

The Finneys Windscreens sure do make a long ride a lot easier. You can carry on a coversation at 100+ and hear the motors. When I put mine in I raised my seats a few inches too. Awesome looking Talon and a fine install!!!!!

[Powerplay25]

Great job. Very quiet at 100 mph.

[WILDMAN]

We went on a 100 mile run today. I'll post more pics and video shortly. Brad had it running 105 today with 60 gallons of gas and two people on board.

[WILDMAN]

Pics from todays 100 mile run for lunch. 83 degrees out! Who ever said MONDAYS SUCK!

Skatin.Need the windscreens got a link?Wind rips over the front pretty good and with the seats where they are you can't get any lower and see. I'm going to raise the front seats if those deflectors bump up the wind high enough.We ran yesterday with 34 lab cleavers running 2 inch above the bottom.It pulled 105 with 60 gals and two people.I'm going to try the 32's again at this height and see what it will do.Hops a little from 65-84 but not as bad as everyone tells me with other full tunnels.Got spoiled with my 21 liberator with the 280's no hop at all:cheers:

[stokernick]

[150aintenuff]

any room to go up more??? and that looked more like a person and a half not a full 2 people...

Gotta lower one motor. Low pressure.

of 72 OZ prime rib MAYBE..... then add in DRIPPING wet, fully clothed, and 5 lbs of lead shot.. might get you to 100 lbs..... :)
