I promise I'll be happy:D :rolleyes:

[B.Mac]

'ta get another 10 mph outta this beast?
B.MAC:D

[Airboater]

How about a V8 and I'll promice you 20 more mph:D

[Airboater]

B.Mac have you tried a chopper on that rig yet.My old 18ft baja ran 74 with a 28 chopper and a stock 200 merc.:cool:

[ShorePounder]

Sandbaggin for B.L.'s benefit again I see. You really are a good friend to protect his ego like that :D :D

I was thinkin a prop change might be in order as well.

[woodco]

To get that boat Fichted !!!! It's broken :D

Hey Pounder !!!!! Ya get that pile of recycled beer cans motor
ya got together yet ????? My kid just bought a canoe with a
4 stroke 15 Rude on tha back and he wants race for titles :eek:

He's really concerned about what to do about yur boat since
he knows he'll win ;)

I said .... Son !!! We'll just donate it to one of those charity's :p

[ShorePounder]

Let's not hijack B.Mac's thread. If ya wanna talk smack, let's start another one elsewhere. ;)

[woodco]

I'll behave ...... ;) I'll wait for your next sermon :D

[sho305]

Try a prop, then you know you can use up that extra leftover resin and mat developing a flat spot on the bottom:) :) just what you didn't want to hear:) Anything you can diet in there? Synthetic lube? Just trying.

Is the LU/skeg all nice? Sand the bottom....has to be something you can do before you put a 300x on there:cool:

[Barefoot Bob]

How much setback you got there and what prop were you running to hit that speed?

[B.Mac]

13" S.B. (8" Panther jack plus another 5" Step n' Jack) and a 5" transom notch for a total of 18" from the non pad to the tip of the bullet.........Running a 25P Tempest plus 6200 @ 68 MPH
The backside of my prop has been cut just a hair to keep my RPMs over 6000. I have not tried a chopper but that might be my next logical step to carry the bow at high motor heights......will ruin my hole shot though...
I can only jack her up to a max of 2" below pad before the bow drops (it flies really nice right now) and I scrub off speed.
Surprisingly, she doesn't loose water pressure until close to centershaft with a stock unplugged LU!!! (all the setback?)

Sandbaggin? That 'Ol OMC of BL's couldn't run 68 with every lobster, and all them curtain climbers standin' on shore cheerleading!!!!!
B.MAC:D

[Airboater]

B.Mac I have that 28 chopper if you would like to try it. I have a coworker that drives up there every day he might be able to meet up with you.Shoot me your # if interested Paul:cool:

[B.Mac]

Is that 28 a big ear prop? If I can spin it, it just might carry the bow if she's a big ear.....might be too much prop. It will give me a place to start though.....Thanks Paul

Have you ever weighed the boat and motor combo the way it sits right now. It would be interesting to see what it weighs. Mine was 1800 pounds and I ran 75 with a 25 Trophy at 6400. My dads Baja is the length of your boat. He has the same motor only the power head was replace with a 1996 2.5 200HP. His gear case is also stock and is running a CMC with the 6" setback and a 25 Trophy at 69MPH. He honastly told me he never looked at the tach. But he was right on my tail when we ran them in fall.

As soon as the ice is off the lakes. I am going to try his stock gear case on mine and see if my numbers change.

And we are going to weigh his boat.

[jamoore]

Maybe you added too much weight when you re-did that transom? Just kidding, enjoyed following your re-build.

[B.Leonard]

First off, your prop is buried. The diff between a surfacing prop and one buried in water is like night and day.

I've been running the same motor on two diff hulls. On the Lund with similar motor height as yours, 5700rpm max. On my tunnel on the surface 6700rpm.

Try the chopper but I don't think you'll see much without getting that motor 4" higher (cone/low water pickup required). But even then, chine-walk and directional stability will be horrendous.

I'd keep it buried and find a motor with more torque. The guy with the V8 Starflight at the Tots run was running 80 with 3 people and couple coolers in the boat!

-BL

[sho305]

With my bow heavy Checkmate, I was told I would have to keep the prop wet and to run something like my Laser for lots of bow lift. It works well but is torquey in the steering. Not sure how similiar the Tempest is to a Laser...my Laser was pretty rea$onable, you might want to try/burrow one anyway. Then again, you may be able to run more of a chopper with all the setback lifting the bow; it seems to make sense in that way.

If you have no pad, you're in the same boat:) as me with the handling/lift issues. I don't know if I want to put a big pad on and loose the rough water abilities my little 17' needs. However, I just looked at a superboat pad that is rather small, and think it may be a fair solution to compromise here. It also looks like it would be pretty easy to adapt something similiar to my vee. I know they are not the fastest, but they seem to handle the rough water well, no chine/handling complaints, and are not a slouch either. I am leaning that way rather than trying to make this hull something it is not.

Maybe BareFootBob can chime in here and tell us how the Rude ran on his for comparison. Might be able to use less setback with a heavier motor if you don't care about brand:) I don't see the Merc having an advantage on this particular hull. And that looks like an excuse to get a second hull for my Merc....:eek: ;)

[Barefoot Bob]

The 225 Rude on my Baja need only 4" setback to get the same lift as the Merc with 9"
I was also going to ash you if that rating plate is for real(300HP)
My boat is rated for 175 and my dads is rated for 200. If your pushing your boat at 68MPH with a 200HP Merc, and the boat is rated for a 300, you are doing dam good;)

[Reese]

Since this is all a big guessing game here goes with my predictions.

1. A chopper will probably not help your cause. (tempest seem to work well on heavier boats).
2. Raising the motor won't either. (won't carry the weight).
3. You need about 50-75 more horses to get to 80.
4. A 12" pad will probably net you 10-12 mph, easily.
5. You can forget all the above and be happy with what you've
got and enjoy the rest of the season.
6. I have my doubts about number 5...:D

[Wile E. Coyote]

A good place to start would be to send that LU over to Bobs, get a nose cone/ low water pickup, and get that motor up. In conjunction with that try a surfacing prop, 27-28 pitch chopper maybe even a big ear to help carry the bow, that appears to be a heavy boat
My .02

BTW congratulations on getting that thing back in the water, it looks outstanding, nice job! (that has got to be the quickest transom replacement project I have ever seen)

Bill

[sho305]

My 17' is rated at 150HP...hard to imagine a 2.5 150 on there:)

Hate to say it, but likely the pad will make a difference. Here is what I come up with so far. My vee is the red in this simple diagram. The green pad style mod of enlarging the lowest strakes has been suggested and proven to work, though maybe not so good in rough water. The blue outline is like a superboat, and the pad is not that wide and has a slight vee. I am guessing it directs the water away and provides some lift, yet will still sink in a wave to help the ride/rough water ability. (feel free to add to this) Everyone says don't cut into the existing hull, though I'd like to chop out a relief of 4" or so for my BR. Seems like the added knees could hold a relief. Of course I would loose some beam with only a 17' too.

Flipping the boat is a pain, but adding a pad has to be much easier than doing a transom! Some just dam it up and pour it. Well, lets try the props first:)

[WILDMAN]

If you're going to the run next weekend, I'll bring my 26 trophy. It gave me 3 mph over my 25 tempest on my 21 Rallysport. Or you can go with twins to give you THIS!!!

[Barefoot Bob]

I would like to hear the results running the 26 Trophy. I have heard the the 25 is gutless next to the 26 and you dont loose much RPM. I also found one to try once ice is out on our lakes.

[B.Leonard]

LOL! Rub it in.

I'm gonna try and make it next weekend. See you there. B.Mac wanna go!?! C'Mon! It'll be fun. First outing for the resurrected 'mate :D

-BL

[Airboater]

B.Leonard if you can get B Mac to go I'll bring the 28 chopper for him to try.;)

[B.Mac]

My wife booted me out of my home office to convert it to our one year old boys bedroom so I've had no computer for three days....not to mention getting slave driven by the wifey painting, wallpapering, etc., etc. NOW lets get back to business here........
Ahhhhhhh, my computer back:D

1st Hey Wildman....... your goin' way to fast there with them twins......I wouldn't wanna see ya in any danger so I'll come pick one of 'em up to bring you down to an even hundred and me up to an even eighty:D Jeeese.......I'm tryin' ta hit 70 and you show up and almost double it:eek: Oh well........:D ;) :p

Reese.........#5, #4, and then # 3 in that order.......
sounds like good advice. That's where I'm headed next.
Run her for the season, then flip it and install a 12" pad and go from there.......Are you saying I could pick up 10 MPH with just a pad/ LWP & chopper?

sho305 ....I like the green pad, nice and wide.

BL.....Where we goin' and what day? Can't do Sunday ;)

Barefoot Bob.......Yep.....That's the original Rating plate all except my little OMC edit:)

Tempest vs Trophy I've heard alot of good things about the Trophy but I'd be shocked to see any better performance out of a stockie 200 than this on this hull...........
Besides....the boat is on the edge of out of control @ 70 with all the chine walking........time for a pad come fall:eek:
I'd love to try one though.......
B.MAC

[Airboater]

B.Mac are you going to east lake next weekend.I havent had a chance to call been working 7 days a week.My baja chime walked at 70 also but was controllable with the motor jacked all the way up.On the pad you might loose your ride in choppy water but it should help alot on the speeds.Paul:cool:

[WILDMAN]

Bmac, my Rallysport was real bad about chinewalking with the Tempest over 70. The Trophy tamed it alot and made it easier to steer. I also picked up 3 mph. The more setback, the better it handled too. I'm running a total of 18 1/2 inches. If you're going, I can bring a 25 Tempest and a 26 Trophy 4 blade.

[B.Mac]

Call me or E me about East Lake....is it Saturday? Near Lutz, Fla?
I'm in if it aint Sunday:D
B.MAC:D

[Reese]

I can almost gaurantee that a 12-14" wide pad will net you at least 10 mph...probably closer to 15 with no other changes along with much needed stability.

If I remember correctly you have a v-bottom with two outside strakes...I'm guessing they are about 3-3.5" wide. A new pad will significantly increase the lift to drag characteristics of you boat, and you'll be better able to use all that 18" of total setback.

Food for thought you have about 210 hp at 68 mph, a new pad will net you 12 mph...close to 80. After that you can modify your 200 to something like 250 (easy with all the engine guru's around here) and you'll be knocking on 90!!!

[B.Leonard]

I think they will be there for 3 days but I can only make Saturday. Not sure exactly where yet Alligator, East Lake, Kissimmee river etc. Maybe Wildman, Bobby or Skip or someone else can fill us in.

I plan on going over and back Saturday. I think they're planning on doing a tour of the chain of lakes or something which would be a blast :)

-BL

[WILDMAN]

YO! BL, I'm going Sat. also. I've got no idea where anyone is going! I don't think they do either. They're talking about meeting at East Lake fish camp at 10-11, then deciding. That way we can be in the water by 1:00! Let me know if you hear anything. If I don't know something by Friday, we're not going. See-ya, WILDMAN

[B.Mac]

I'm wit ya BL....you bringin' the Sterling? I wanna ride in that thing now that ya got them OMC gremlins worked out.......
besides ......I dont think ya wanna try flexin' 'yer Lobster claw on me now since I put the exhaust relief plugs in the Tempest
DUH.......DUH.........capital DUHHHHHHH

I was spinnin' 6500 standin' still and couldn't figure out why I had no hole shot. Three little plastic plugs in them big 'ol prop holes and a little hole drillin' & testing to dial 'em in......5/8" holes did the trick.

I was gonna name the boat "Higher Powered" but maybe now I'll call her the "Lobster Trap":eek:
BLAHAHAHAHAHAHAHAHAHAHAH.....BWAAAAHAHAHAHAHAHA:D


On Lobster Patrol...........
B.MAC:D

[B.Leonard]

It's runnin strong. The 235 is sportin a new set of heads and is stronger than ever. It is an absolute blast to drive, incredible torque now that twists the whole boat. The stock porting is keeping it from going over 6500-6700 so 90 is about the limit with this fishing motor.

I'll be swapping it back to the Lund soon and we'll have it out. I have picked up a special prop just for the 'mate :D That combined with those new heads will have you starting your "pad" project REAL soon :p

I'll call you with the details on next weekend. We might head over to Daytona for the whole weekend and launch operations from there. We'll see.
