2750 bottom changes
 

Incorrect

Maybe Quent will chime in I think he just went through this or the lavey boys!!!

I have an 02 2750. After a couple of years of a porpoising problem and trying numerous props and tab settings I finally had the bottom blueprinted. Some of the lifting strakes were removed and a couple were just moved. The difference was amazing. Now there is no porpoising at all and you can run it close to 100 and it's as smooth as silk. It is a fantastic boat with an amazing build quality and now has a ride to match. I love it and it was worth the investment.
I hope you decide to have yours done because it is an amazing boat.

Good luck,

Tom

bottom work
 

Did the lavey boys do the work or some other shop???

The bottom on the 2750 has been modified. The official change took place a couple years ago. Like hotlavey said, the lifting strakes were removed and some strakes were completely removed. I'm not 100% sure of what his boat had gotten done but Lavey took off the lifting strakes on the rear and middle pad, the strake closest to the keel was removed on the rear and middle pad...
The mold has been filled therefore all new 2750's have this bottom mod. As to your question if an older boat can be changed, the answer is yes. This can be applied to any of the 2750 bottoms and still remain solid.

With this "new" bottom the 2750 handles quite a bit better. No more, or very little, porpoising or chine walking. And because it handles better, you are able to control the boat better and gain a couple mph or add more hp and be safe.

If you want this change to be done, I'd recomend calling Lavey and taking your boat to them to do it that way IF something does happen to the lamination on the bottom down the road, it will be backed by Lavecraft.

I had the work done at a shop in Lake Elsinore in So.Ca.
I'm sure Lavey, with the knowlege they now have, will do a great job for you too. At the time I had my work done Lavey was not doing bottom tweaking so I went to the folks that were doing my engine work and maintenance. Send me a PM and I will give you more info.
Lavey Jr mentioned that there is very little porpoising or chine walking with their new bottom. I have absolutely no porpoising and no chine walking at all with no tab use. Perfect ride.

Tom

Thanks for the help.
Hot Lavey - email me if you would the name and number -
[email protected]. I'll call Lavey as well if I get one and get a bid for the work as well.

Hot Lavey - what motor/drive package do you have and what prop are ya spinning?

Thanks,

Chris

For what little I know, here is my take. The boat simply had too much lift. That is great for ocean racing and ocean running but for us blue collar guys on the lake, it meant you had to "drive" the boat all the time at any speed at all. Tab dragging and stuff.

I grew up running and racing outboard pad bottom boats and "driving" can be fun and was, in fact, the order of the day. As I've advanced in years, I've come to appreciate going fast and not wrenching the wheel all the time just to stay upright. Nevertheless, on the edge driving is a rush, just not healthy. Quent

Yes, I say very little because there is no 100% gaurantee that the boat will not porpoise or chine walk. You can get pretty much any boat to do either one of those.
In reality, I have personally driven five 2750's with this new bottom and none of them porpoised nor chine walked, but it is still always a variable to be mentioned.

Absolutely correct. I was just stating how mine handled, which is awesome. This boat is incredible, both ride and quality. Before I had the bottom done I was ready to sell and move on to something else. No way would I sell now- as someone once said "Out of my cold dead hands". Glad to see you folks have changed the bottom, that is all that was needed.

Hotlavey - got your email....thanks!!

How did the boat run with your stock power? Did the boat change for the negative after you put the Whipple on it?

Thanks,

Chris
I read a boat review on the 2750 with the 525 package....all high marks - so just wondering if these issues you had were from more power, more torque and bigger prop???

Thanks again!

Boat ran76-77 gps but had a ton of porpoise. Would have been faster if I could have avoided using the tabs. It was a great cruiser from 65-70 and could handle just about any water(Like Mead on a windy day). Over 70 or so it was not too comfortable. Today? Ahh Nirvana!
After the first Whipple(2.3) same problem, just faster. 2nd Whipple(3.3) and a Imco shortie, not much difference- no better no worse. Bottom work solved all the problems. I should have started there first. Best investment I made with this boat.

Hope this info helps,

Tom

The 2750 with the "full bottom" was excelent and had little issues running in calm water with 496, 496ho and 525. Although, there are a few 525 boats that just didnt like it and there was no real reason as to why they performed different...
with smaller power like the 496ho it ran beautiful and most of the time would run 70-75. This is so because the hull had so much lift, it would help out and give all the added lift the smaller power needed to run fast.

But then as you start adding more and more power, the boat just lifts more and more as speed increaes and at that point it becomes a boat that is classified as a "drivers" boat and you need to know how to drive it at higher speeds...

So with the "new" bottom, there is less overall lift which tames it down and is more controlable with high power. Also, there has been zero negative aspects from this bottom change, even with smaller power. Rough water handling hasn't been sacrificed either.
Another benefit from the change is that it requires almost zero tab input to keep level (depending on your load distribution) which in return is less drag which will equal more speed.

I hope I answered your question.

well gents ...... im certainly not as knowledgeable as you all are but
here goes
i am still in the small class with a 26 ft nu era but this boat is amazing......
i dont have to trim out as far to get speed like i did in my old sled
and someone made a comment about the boat just slowly lifting and the speed climbing
and i still dont have the right prop
soon to be rectified.........
i purchased a 24 p for everyday running
and a labbed 26 from cutting edge propellers
i find that i can get a bad chine walk if i trim out to far
back the trim off and feel her fly
was out last weekend and got 68mph in dead flat water with no wind or ripple 2 old carcasses and a full tank is fuel
i am impressed
i zero my tabs and the slightest touch is all it needs to make the hull dance into instant response
combine that with a bit of steering and i swear it feels i could carve a turn at WOT

i cant wait to go out tomorrow,,,,,,,,

Had the new boat out on Castaic on Saturday....had some wind chop and the boat ran soooo nice. Can't wait for Havasu in a few weeks!!!

Schweeng- did you buy the 2750? in the picts?

Uncle Dave

In the pictures??
Yes I bought a beautiful 04 2750..... love it!

I'm back on the water....:evilb:

Awesome!
That was a sweet one too.
One of the nicer ones Ive seen come up for sale.

Congratulations! & Welcome back.

How any Laveys does this make for you?

Dave

3rd one...
1st single 29 ever made
1st twin 29 ever made
and this one.....
http://images.traderonline.com//img/...mb_550x410.jpg

Besides my twin step Cig this is the cleanest used boat I have every bought.

Uncle Dave you doing the SCOPE run at Lake Mead??? Come on its Fathers day weekend.

I may- issue is I have the whole week after off- and its going to be hard to put the 2 back to back.

Enjoy!

Curious- Why did you get off the cig?
Guys that own them are like cult members.

Centless- most of these boats neither like, or need lots of positive trim and if you do do that it starts moving around on the pad. Keep it neutral or ever so slightly above that and youll be sailing along efficiently and likely faster than the "next guy" with the same power and length.

I would still love to own that boat...just way too expensive!!

I think I'll be at Mojave Lake for Memorial....that should be fun!!!

As in more expensive than any normal 2 engine boat?
Or as in it had a bunch of problems you chose not to deal with?



Memorial at Mojave should be a blast- I love that Lake.

UD

The TS Cig had zero issues....the monthly nut -yikes!!!!

That brand and a select few others....ya get a down right awesome boat but you are paying for the "brand" for sure.

Trying to figure out Mojave RV or Cottonwood....towing the lavey with a RV and don't want to have too long of walks back and forth from the RV/dock.....

ahh got it - completely understand.

Those are VERY nice rigs.

What I cannot tell is if they are any nicer than a comparable rig from the West coast to justify the price delta being in the "club" demands.

Either way - hope to hook up with you this summer.

UD

They are nicer by far!!!

It's like having a new Corvette ZR1 (badass car) vs. a new Ferrari ???....

They might be similar in certain aspects of speed and performance but getting into the nitty gritty or an overall view....the Ferrari will take the cake for the majority of people...

Good info, I have only seen older versions on the water and seen them at shows.

Other than 6" pipes I didnt see much that different from any other v bottom.


UD

Schweeng,

That's my boat- the exact paint scheme. I thought this one went back east. Looks good.

thanks uncle dave i am finding that out very quickly in my old sled i had to trim out till i was just about blown out to get speed
this weekend i kept the trim below 1 up to 1 on the guage and she was glued to the water no chinewalk or porpoising of any kind
tested a labbed prop today from CEP
they made a mistake and shipped me a 24p instead of a 26p
already rectified cant wait to try out the 26 next weekend
the freshet is a week late here im hoping i get one more weekend before the big jump after that its rafts of solid wood for a couple weeks and a couple more weeks of chunkies
