Not your avg 270.. Boating content

[Nord]

You and Nord should kiss and make up again!

Steve knows his shit. As a matter of fact, I think the boat should be taken to Mead (what the 27 Hallet is perfect for) for a few days and test a couple different set ups instead of being spread out over months. This thread is a wall for ideas and I think everyone is throwing ideas at it. Everyone can throw an idea out there not just one person. Some may stick, some may not. The boat is sick. I hope it all comes together.

What's the latest ? :thumbup::thumbsdown

Curious to what GT says is the fix? Or what they are going to try next?

[Cole Trickle]

The Boat is stunning to say the least.....

Sometimes when you push the envelope things don't work out as planned.....The 21' Arneson turbo Eliminator Daytona comes to mind.

I hope they get it figured out because that boat is floating artwork.

I agree. Why is it up to the owner to fix this problem. GT should be all over testing this boat and figuring this out.

Probably not a good idea to be calling out a paying advertiser

I don't care if they are. I'm plaster Dave not river Dave.
Bottom line is it's not a call out its reality. This boat was customized by them they should make it work.

 

[skav]

So here's what I'll do. Trade straight up. My 270 for yours

Let me know if your interested quick, because I'm already having second thoughts!

 

[RiverDave]

GT isn't an advertiser? Not sure anyone was calling them out or not either. Just asking what they're next step or thought process is in dialing it in.

In any custom creation like this it isn't going to run bitchen first time out. It's a process, and one the membership could learn a lot from.

The reason I ask, is because when I was looking at boxes, IMCO told me that if I used a neutral box, my drive would be 2" lower than it is now.

I asked about a -2" box, but you would need to rise the motor 1" (I think, maybe 1"-2") for proper alignment.

The reason for that is because the IMCO box is built with an angle to account for the angle of the transom. I don't remember what that angle is off hand, but for some reason 14* sticks in my mind. But not all boats are built with the same transom angle. If your boat has a higher angle, then pushing the drive back will make it deeper and vice versa. In theory, if you had a 14* transom, then adding the box would not change the x dimension.

The Hallett in question is set up very similarly to this Hallett for sale which I believe ran 90 with this power. In the side shot, look at where the nosecone is in relation to the keel and you'll see this boat also has a very high x dim. I doubt its the tabs, a lot of Laveys run those long planes with no problem. I doubt its the extension box, I've only ever heard of a box helping a single vee. The only glaring difference between the two boats that I can see is the hull work. Changing props and x dim can change the handling of the boat, but it seems no matter what you do it keeps lifting the transom, I'd look at the hull again.

Any thoughts on how the tabs are mounted. The tabs in the link are mounted with the "V" of the hull. The tabs on the boat in question are mounted flat.

 

[Skinny Tire AH]

From the peanut gallery. Last summer, there was a 28 speedster here with twin 1300's. Boat had a very similar problem. I understand, it was a cat with twins but the boats seem, from what I am reading to have very similar issues. That boat is owned by a friend of mine. It was sorted out by the drive(s) being blueprinted. I left off all the names for obvious reasons.

The 28 Speedster runs numbers like The M35's with 3000HP do. Again,I get it, different hulls and different power but a very similar problem. Perhaps look at the drive profile? The drives themselves on the 28 speedster were lifting and causing the boat to be un-drivable at 105 and up. Runs 175 now. I didn't read the entire thread, if this has been looked at prior, my bad.

Just throwin it out there.

 

[Crazyhippy]

Do nose cones cause transom lift?

The argument has been made, that when run high enough, the bullet on the drive will act like a hull, and end up on plane, which will provide stern lift... outboard guys run into this issue when WAY above the pad (2" up and 12" back... boat will not even plane out without a hydraulic plate to drop the motor.

 

[Crazyhippy]

Other thing is how would they know where the X dimension is on a bottom that is a one off? They don't.

X dimension can be measured with a tape measure... They may not know where it needs to be, but where it happens to be is easily measured.

If that's the boat I think you're talking about, it was way more than blueprinting. The issue was SCX4 vs SCX lowers, drive spacers and cleavers vs Bravo style props. It did get sorted out damn well though.:thumbsup

They're also much smaller.

No actually I've heard that mounting them flat is actually better and gets them higher out of the water. Most laveys are mounted flat and I remember the old Factory 1 Warlocks always had them mounted flat as well. I don't see that as causing a problem as they've described with excess transom lift.

 

[rivrrts429]

I noticed that as well.

But the same boat in your link doesn't have the tabs mounted flat? And that boat runs up to 80-90 without issues. Might be worth a shot.

To me, it would make more sense mounting them flat for ocean use. Not so much for smoother water like the lake or river. Unless it's a bitch to get on plane.

My guess is that those tabs never run dry and are a small part of many other small issues adding up to one big problem. I just hope the bottom isn't one of them.

I'd spend a few days doing nothing but making small changes and testing. Get some sort of data on which direction the boat begins to feel a little better.

Good info in this thread though. It will be fun to hear what ends up working.

Exactly. Its worth a shot to take the tabs off especially for how easy it is, you can do it in the parking lot at the lake and run the boat back to back for comparison. Small changes is key though, change one thing at a time. I'm also curious to know what ends up working.

Yes, all those things were tried. None of them made any difference. The blueprinting is what allowed the boat to be driven at those speeds. It went from un-drivable at 120, to handle well at 175, overnight.

Joe say's it's the bottom..

 

[RiverDave]

Joe say's it's the bottom..

Who is joe? What are his ideas to fix it?

 

[hydfixer]

i am the guy with the 28 speedsteer. We tried everything and spent a bunch of unneeded money. My boat acted the same as yours we tried Bravo props different pitch and dia different ride heights, blue printing the bottom all that did was to move the MPH where the problem started up or down. Eliminator had a single drive boat with the same problem. I went from a boat that was uncontrollable at 80 MPH to a smooth ride at 174 MPH By BLUE PRINTING THE LOWERS ONLY.
Call Brad at E Ticket boats.

 

[Nord]

So shouldn't Hallett fix the bottom?

 

[CampbellCarl]

Could we pause for a moment and define..."Blue Printing" It may help all of us understand how/when that term is used.

In my world, 'blue printing' is nothing more than insuring that the original design build and specifications are 100% as intended by the original engineer/designer.

I'm dumbfounded that the Speedster problem example above was resolved by closing up or tightening up bearing tolerences, gear lash, load and preload clearances all done in the drives.

Anything is possible but could we get a clarifiction on the words please...

CC

Again, the part in question matches the blue prints for said part 100%.

 

[Skinny Tire AH]

Outside Carl, not inside the drive.

Supposedly it is a modified hallett bottom?

When they are talking about blue printing drives.. They are just changing the shape of the lower and skegs etc. It's not a good word to use to describe the process, but that's what they call it.

Ironically enough blueprinting bottoms isn't a good word in that description either. Lots of boats were designed to have hook / rocker in them etc.. And when you straighten them, you are going away from the actual design intent..

[Nord]

Who modified the bottom ?

 

[spectras only]

whatever happened to the ventilated bottom one that Supercrewjohn was ejected from?:hmm

 

[ToMorrow44]

Teague just posted on Facebook the other day that they just got a new set of SCX-4 with the "new" lower unit that is supposed to be blueprinted after figuring out some stuff on an e-ticket. Sounds like IMCO/Teague/E-ticket may have tweaked the design to work better.

 

[RiverDave]

Who modified the bottom ?

Like I said supposedly it's a modified bottom. I'm not sure that it is modified, maybe? Who knows.. We have a single step one here at the shop, I wanted to put them side x side and measure everything from the bottoms to the setups, and drive them both to see if one runs better then the other and figure out why etc..

I think Andrew might have done that, but I wasn't around.

I believe that was a twin step, but don't quote me on it.

maybe screw some wood to the bottom for starters just a thought.:yikes

what do you think?

 

[Blubyu]

Why would Hallett change the bottom that they've had working for so long on other 270's? (straight bottom)

Unless this is just a one off bottom from hallett?

 

[RiverDave]

I'm sure you guys will get it dialed in.

[plaster dave]

I thought I heard GT modified the bottom.

 

[Gelcoater]

So my friend has been building this boat for the last few years, its not your average hallett 270. So for the next few hours we have to try and find some kind of prop that will work on this boat. He has tried a few but they have all been weird worked over one off jobbies.. We will start with a 34 Maximus five blade and see where it goes from there..

The boat has more custom work done to it then just about anything I've ever seen. It's not even a Hallett Bottom anymore. Note the delta pad, different steps etc.. This was a boat that Gary Teague (GT Marine) was building for himself, and my friend purchased it midway through the project. I'll add a couple of pics of some of the custom stuff I noticed right off the bat.

[Racey]

Anything done to the bottom of that boat after it came from the factory would almost definitely be an improvement, it's no secret that those 270 step bottoms have issues, the 290's were really bad, I know more than a few people that spun them out on separate occasions, 4 good friends of mine got ejected from one, and these were not amateur boaters.

I would tend to agree that the bottom is still causing the majority of the issues, short of turning the boat upside down and totally re-designing the bottom, any 'mods' to the bottom that GT did still have to fall within reason as to what you have to work with from the start, there is only so much that can be 'modded'.

The straight bottom 270's worked awesome, Anyone that has ridden in Lynch's 20+ year old one can tell you that, that fucker runs hard, and true, and in the 90's.

It's a gorgeous boat, and the 270 is one of the most versatile configurations on the cockpit/cabin side, I hope they end up getting the thing to work to an acceptable level. AK is a great guy, and has lot's of patience luckily :thumbsup

What's the latest ? :thumbup::thumbsdown

Do you really want to know? I've ridden in and driven a few Halletts. This boat is so wrong. I don't know if you guys rigged it, but it's horrible. I spent a day this week driving it. From the channel up to Topock. The motor is no way 1300hp. It was blowing oil all over the bilge. The boat no matter where you trim it won't get over 5000 rpm, and 75mph. It's slow, handles horrible. Motor is weak at best. I'm sorry. The Big K is a close friend and he got royally fucked on this deal. Someone needs to step up and make it right.

The water breaks just past the open bow. It can't carry the nose. I'd say the x is way high. They tried a three inch spacer and it's still too high.

A 270 Hallett with a brand new 1300 hp 598 and 8 liter Whipple should pull a 30 pitch prop and 1,26 gears past 5k without overheating and blowing oil out of the breathers.
