Rebal knows he had one once and he still knows where it is 

I love the 21's nice riding well built boats...i have had 3 friends that have owned them....my friend had a stock 460 with a jb a in it and ran about 52mph....

My 21' will run 56mph GPS.

thanks for the info, i do a bit on running on Lake Michigan, and was wondering how it would handle the chop,    did you refoam after replacing the floor?    this is also a 78 model

  don't no chit about fords but will figure it out,    my old man has a f-700 with 460 would this be a better block to work with [rods?].     the one for it is pulled apart with some pretty good ring groves,    stock oil pan ,     dont know if its the original motor,     he said one of the heads cracked and had an extra set.      last registerd in 98 so its been sitting awhile

 pulling the floor wont be any more work than what i have on the Cobrajet,     the floor is out on that one but the hull is cracked along one of the strakes where the floor sets in,     the hull is pretty thin on the cobra.

 actually looked at the biesemeyer for parts but think i will be money ahead on this over the cobrajet

man that would sux, that wasnt yours on the u-tube vid out on the water?

 the hole glass tank thing doesnt sound cool, want to run e-85 and heard the glass doesnt like it
 
 would have to make some custom tanks, they are a weird shape from what i saw

thanks guys, I ll have to crawl under it, im just asumeing the floor is shot, didnt find any soft spots but the interior is shot,only looked it over quick, offered the guy 250 told him i wanted it for parts

Ya never know if ya dont ask. I got my '23 sleekcraft for $75 by making a smart ass offer...fitty bux. I was just kidding but closed the deal for $75.

Yea that fucr had three flats, rubber flyn all over the place. Then went to look at this house I wanna buy and there was a set of universal aluminum wheels and tires stacked in the driveway...T/Y

man that would sux, that wasnt yours on the u-tube vid out on the water?

Ya, the one on you tube burning is Rays old Biesi!

that would have made me sick watching my boat burn

You have no idea dude! The whole story of that day is funny as hell, well, now it is, wasn't at the time. 

I'm wondering about your mention of fiberglass tanks? Mine were aluminum? Regardless, E85 (From another discussion over on PB that Proppy and I started) is perfectly fine with fiberglass. Someone even mentioned it's stored in 'glass tanks at many facilities. If anything, I'd be more concerned with it on aluminum parts (alcohol eats aluminum) and not store it with fuel in the tanks, otherwise you should be fine.

John, I'd love to dive that wreck and see whats left! That swim deck was perfect! But, its been under about 175 feet of water for a year and a half........ cant save a thing now,

thanks BeerJet havent had the extra cash with the wife and christmas shopping, but soon i hope before we get to much snow

Ray, I do know that at least some of them had glass originally. I remember the one my parents had when I was a kid (dont know what year it was), there where cut outs in the interior side panels where you could see the tanks. Was kinda cool because you could see through the fiberglass and tell how much fuel was in the tank.  I remember watching the fuel slosh around in there. 

 BTW, they might be great boats but as a kid I hated that boat !!!  My mom talked my dad into selling your mech injected wood deck flatbottom to get that thing (more family friendly).  I love my mom, but I will never forgive her for that. 

WOMEN!!  LOL! Well, I can't say much, because I've said many times before if Cin were still with us, Moo woulda been started up in the garage, ONCE, and probably been on Craigslist inside of 10 minutes after that event! As it is, I've had free reign on these things. 

Omar is the Lord and Saviour when it comes to hulls, and I'll never doubt his word. My experience, and I stand behind my statement, has been with pretty much stock, docile hardware. Throw 600+ HP into a 21' Bieser (or Nordic or Sanger) and I have no idea what it'll do. I know mine was a Bieser because of the tell tale drop outer chines that even the cruisers had. I CAN tell you what it'll do in an 18' and a 20' Sleek, however  , and as Proppy pointed out, we're about to find out real quick what nearly double THAT will do to a 1/4 stringer 18' Sleek    .  Could get ugly.........
Omar makes a valid point, and Proppy endorses it, that Biesers were inconsistent and made in several places. Mine in Phoenix, WAY before the drunken stupor that led to the end of that companywhen it was in Globe.  A '78, you're safe, made in PHX, Heavy layup, good to go.

I'm in a deal, personally, that I'm not even gonna try and explain here, you guys are brutal, and why I love you all! But I'd love to have that sloth old Bieser back! I think it'd be proper to break Carol in on that, then throw her in Nick or Marcs boat to see just how bad it COULD be! I'd be in a much better position to be able to sell whats under construction here a little easier,     

In my personal opinion, and many on the site were in or borrowed that boat, it came up on plane inside of 30 MPH, and left me no reason to beleive it was NOT capable of 70+ pretty handily and still maintain it's nimble handling. Woulda taken a LOT more than 600 hp to get to 70, but I doubt the handling woulda have changed though.....
