33 avs speeds?
 
Looking for some real world input here. So I've decided that while I love my boat I want a stepped hull for the speed advantages. My friend has a 35 fountain big step with less power than mine but it's a solid 13 mph faster than mine. I want to hear about 33avs speeds. So if you have some real world experience post your hp and gps speeds. Thanks.

a friend has a 33 avs with 500efi, mid 80s

chris21hope 12-25-2014 10:12 PM

Rebuilding power now, but my 33' w/ hp500s got 80mph even.

Not sure how nailit's friend got mid 80s - maybe he has boxes too.

Seeing mid 90's with 750's but still dialing in. Not getting enough rpm yet

Indy, don't you have the Scarab School Boat?

I know when I spoke to the owner of the P31 he said his boat ran 80 mph with the HP500's. I would think that your hull and the P31 are the same layup schedule. What speeds are you running in your boat now?

indysupra 12-26-2014 08:26 PM

My boat runs high 80's but takes a lot of power to get there. boat ran 82 with stock 502's with m1 procharger at 4 psi.

I use to have a 98 33 AVS with 525 SC with intercoolers and solid cams. Motors made around 625 hp. Boat ran 93 at best. GREAT boat.

That seems inline with what I was thinking. That boat would be easier on parts than my boat running wetter and slower.

Do you have boxes on your boat?

I have owned a stock 502 mpi 33AVS which ran 76-78 spinning Bravo 28s depending on conditions, a stock carb'd HP500 33AVS which ran 80-82 spinning Bravo 30s depending on conditions (a stock unit will not run mid 80s), and the stock 600DPX (560 prop HP) unit I currently have which runs 90-92.

indysupra 12-27-2014 03:09 PM

Thanks for the input. That puts me close to where I want to be. I was thinking about putting my power in one and then turning it down just a bit.

What speed do you think that boat runs out of hull?

There are, or were, as I have lost track of them, at least a few, that were running in excess of 105. One gentleman from NH whose boat I had looked at as a possible purchase had approx 900s and was running around 107 with some set-up changes.

indysupra 12-28-2014 08:47 AM

I would have though faster with 900! I want to run 100 but it sounds like it would be cheaper/easier to start with a fountain 35.

I would agree, and my personal opinion is that it could run better with that type of HP but you have to dial the set-up into it, and it just hasnt been tried/perfected yet as a model to follow, like combinations have been done on other types of boats.

SPECTRECAT 01-17-2015 11:14 AM

Yes that's me. Who is this. No i did not have boxes on the boat.

DirtyMoney 01-18-2015 06:10 PM

I do have boxes and -2 sportsmasters

Built a 99 for a customer with 602 NA number 4s it ran just over 100MPH motors were around 700 HP if memory serves me. But never got it propped right before he sold it and went racing.
