how do I optimize the hole shot on a 1989 Baja 280 sport ?

Not sure what you are asking?

Mine gets out of the water real easy. Drives all the way down, I don't even use the tabs. With my 3 blades or 4 blades and can hammer the throttle and the boat will jump out of the water. I don't do that though. I just give it maybe 1/4 throttle untill I fell it start to come over then I will stab it if I am in that mood.

Even with 8 people in the boat it has no problem getting up. In fact it will almost get up with just one motor running.

I have 454 mags

Here is a video of it http://www.youtube.com/watch?v=Dati5JuLvqg

Here is another video of it taking off. I take a few seconds because the river is not very deep so I was making sure I would not hit bottom

I do same. Just ease it up slow and once it starts to roll over give it some more until you on plane.. 4 blades will get yo on plane faster and have a better cruise speed sometimes you get better wot speed but more than likely you lose a few MPH with the 4 blade..

thanks guys for the videos and the advice.I do just that ,I get it rolling then ease it up a bit until it feels like she wants to go then I can crank it up.
I thought that I could just pin it and it will rock but it wont. Im running stock 454 mags and 3 blade 23p props.
I thought that something was wrong when I pinned it and it woudnt go but if like said; I get it moving and ease it up until she wants to hop up and then gun it, it runs like hell Its a great boat and lots of fun for me and my son,my wife hates it...want to see what the speed is at 5000 rpms but I gotta wait until I have really good weather for that .At 4000 rpms on Sunday we hit 54.8 mph.The weather here on the Great South bay long island NY gets rough in the afternoon so gotta wait for good day to really get her cranking thanks again cool videos keep em coming Ill thry to post one too.

I can pin mine from the start. It will rocket out of the hole if I do it. It's just not good on the drive.

Your speed sounds about right. Not sure where I am at 4000 but it has to be close. Most of the time I am running with 1/2 tank of gas or more with 4 or more people. 5000 RPM I am right around 67 68.

Couple shots of mine running in this one at 217 & 511

I've run a few of them and never had any problem getting them on plane..... Mine lives when I stab her from the get go....lol...

right on ,I took the boat out today with 3/4 tank of fuel 2 passengers and me on a calm bay and punched it out .It jumps right out of the hole and starts to fly

Just remember hammering it from a dead start you will eventually just sit there because there won't be a tooth left on any of those bravo gears... lol just be easy on your drives and keep the props in the water and they will last a long time..
