Yes, boat liked to chine in the high 60's/and 70's. You had to drop some tab. But of course, when you drop tab, you loose top end. I noticed the boat wouldn't chine until you got into a little chop or a wake that started you to rock. Mine had the stock, twin rammed tabs.

Deep Vee, no pad....It's the old saying "It's like balancing a bowling ball on a razor blade".

Hydraulic steering will take care of the chine walk. You need it if you're going to run that fast.

No it won't. It makes running faster safer because there is no cable to break & no tiller arm to break.

Well, I was planning on the twin ram steering, but I will be running in the GOM down here in SW Florida. Don't get many days that are flat calm here. A lot of 2-3 days, with some days bigger and some days smaller. But I was always told if you want to run 60 mph all day long, have a motor that will run 80 mph.
Thank you everybody for all of the imput. The first of next week I start the transformation from stock to modified. I will keep you updated on the progress.
Tank, love your old boat!!! Once Baja, always Baja!

before my sh&t was stolen I got out for a couple of test runs with a 2'' shortie and new carb on my 509 650 hp add on steering going to full. with the add on it still chine walked above 75gps, I hit 83.2 with 75 to 80 gals 2 foot chop at 5900rpm to 6000rpm with a 26 b1, but you have to fight the walk . I hope when its back together with a bigger prop to hit 86 or so. about the box I was told no boats to short. but a guy in germany has the 25ol with a 525 3'' raised box and is hitting 81. mine is a 24ol 88. if you look up pics of my boat you can see what I did or call me, I have made changes since I bought it in 1990 art ps the shortie made it handle the rough water better flys level and add the 380 k planes to.

Looks like the motor will be done the end of this week, first of next week. Decided to stick with the 454 block as most of it was in great shape. So, bigger cam, new exhaust, new intake and carb, new ignition(distributer), roller rockers, ...
Should be in the 550-575hp when it's done.

If anyone is interested in a "Cool Fuel" MPI fuel injection system, let me know. Mine is for sale.

Motor is done, 10 hours break-in time is done, time to start figuring out the prop selection.
This is what I am working with ...
Cam is a little hotter than a 500hp, 750 Demon dual feed carb, Merc Thunderbolt Ignition/Distributor, Revolution Marine Exhaust Manifolds, 4" Pipes, ...
Broke the motor in varying rpm's up to 3500. 22" 4 blade barely hooked-up, went to a 26" 4-Blade. Could not keep it hooked-up. Tried the original 3-blade 23" and as long as it was trimmed in and very slowly accelerated it would stay hooked-up.
My best speed was 59mph at 4000rpm with the 26 when it hooked-up once hit a small wave and so much for being hooked-up.
How much bigger should I go? 27" 3-blade? 28" 4-blade? Bigger???

I use to spin a 26b1 at 5100 to 5200 with stock drive with a 650hp. now it was hitting 6000 at 83 with a 2'' shortie before the drive was stolen. you should try a rev 4 25p if you have 550hp . I ran a 25mirage with 400hp to 4700, at 580hp 5600. you can test props with BBLADES ask BRETT. THE STOCK OLBAJAS LIKE THE REV 4 AND IF YOU HAVE 500 TO 550HP A 25P SHOULD WORK FINE YOU SHOULD SEE 70 TO 73, ARTIE
