I Am Working On The Same 28 Thunder As Steiny. Can Someone Tell Me About Why To Run A Lh Prop On The 28 Thunder? Also.... I Was Testing The Boat Out, It Has A 4 Blade 24 Now And Seems To Have Alot Of Prop Slip 4800 Rpm At Best And Saw 68 Gps. Alot!!! Of Porpise At Top End. Does The 28 Thunder Typically Porpise? And Will Just A Liitle Tab Make It Go Away. We Need Some Help... This Maybe The Last Weekend To Test Before It Gets To Cold. We Do Not Have Heated Storage For This Boat And Will Need To Winterize Soon. Cant Wait Until Spring To Do This. It Will Bother Us All Winter If We Cant Get This Bad Ass Thunder Running The Way It Should Be. And Yes.... I Am A Sonic Owner But I Love The Thunders The Same As My Sonic. They Both Are The Coolest Boats On The On The Water. Just My Opinion. Thank You All In Advance For All Your Help. Think Spring

The only thing that I can comment on is the porpoise at top-end. I have never experienced that.

Also, 24P seems small...

I ran a 24 lefty on my 496 boat for nearly 300 hrs and I never saw it porpoise. I would think that thing would pull a 26 with ease and maybe a labbed 28.

Try a lefty B-1 26.

Single screw boats naturally torque to the right. The left handed prop offsets this some what.

If you're porposing at wot, you're most likely trimmed to high.

What year is it? I never had a porposing unless it was trimmed to the moon.

I'm dropping off a 26p labbed, 26p stock and a 28p stock all LH for him to try sat. and he already has all of my RH props. I think we will figure this thing out this weekend. Thanks for all of the help guys. we will let you know how we make out with it.

slboatdrinks, boatfreaks and you all had/have the original hull. Cosmic and Glad have the new one taken from the 32.

The original 28' would torque too much out of the hole and that is why we tossed the LH on it.

I will also say if there is a 24 on her, somebody changed it. 26 was standard. Looks like you have a few others to try this weekend from the Sonic guy. I like having that 26 stock and 26 labbed back to back. Those are my choices. The 28 will be a waste of time.

Let us know how you make out!

I forgot to ask, who actually owns this boat???

His Name Is Eric. He Is Part Of The Williamsport Pa Boat Gang.. Better Known As The 3bc .. The Boat Is A 01 28 With 500 Efi Stock. He Was A Baja Owner And Should Be Joining The Oso Gang This Winter When He Gets Some Down Time. We Will Keep You All Posted With Our Progress And Results Of This Weekend.
