Any Roger's guys out there??

[707-CREW]

I have a 1987 21' rcb day cruiser and have not been able to find out much about these boats. I had to sell the 100mph sanger flat years ago and get a boat with some back seats for the two kids. I bought this boat a few years back and it has been an awesome boat. I think it came with a jet but the original owner had a king cobra 454 i/o installed. The boat handles excellent and I have got about 68-70mph with 2 people in it. It has the shift cone set up and I was told this was the best cobra outdrive made. It was installed in 93 and was suppose to be the hot set up back then........I guess...well they are now gone...anyway..I need to go at least 85-90mph to be happy....Will this hull handle more ponies? Is it worth puting money into this boat? what would be the best way to get more mph? Is a rogers hull a good design? any info or thoughts would be greatly appreciated.......thanks

You'll gain 10 mph with a larger prop and about 5 lbs of boost. Staying in the same rpm range. Be carefull with those cast pistons though. I think they are only truly good for about 3 lbs of boost but be EASY on it and use it sparingly.:D

I have no blower...if this is what you are talking about...thanks

They are nice hulls.
Old Rigger here on the boards could give you more specific information as he has good insight into Rogers boats in general; but I would put them in the league of a Spectra or Howard as far as performance capability as they are similar in size/construction.
Specific to your situation, the first thing I would want to know is whether or not the boat was really a jet coverted to I/O. That may raise some questions as to who repaired the big hole that would be in the bottom of the hull from the jet intake and whether or not the area is structurally stable for the stress you're going to be adding. With the boat being an 87, there is a decent likelyhood that it could have come from the factory with the outdrive since I believe that package was available in 87. But again, I would defer to Old Rigger here on the boards as he might be able to say whether or not any were ever rigged from Rogers with that pacakage.
So basically, it is possible to go those speeds, if the hull is in good shape, the Rogers build would warrant the strength to support the speeds, and the hulls are easy on the eyes to boot.
Now if you're actually going to buck up and try for those numbers make sure you budget for full hydraulic steering and save some money for a good set of tabs just in case you end up needing them.
Nice boat, and good luck with it.

Nice family cruiser. I see that your boat is on craigs list, Did you change your mind and decide you build it up? Roger is known for building high quality fast hulls. I'm not very familiar with the VIP hull, but I'm sure Oldrigger will give you some great advise. He worked for Roger. Good Luck!!:)

from what oldrigger has said before, i think that 21 was made from a Conquest mold that Hallett sold Roger. the bottom is a Spectra design. and as said allready, Roger was know for building good strong hulls. so you may actually be able to put some real good HP to it and get some good speeds. lets hope Rich chimes in here soon, and sets us all straight.:D

[throwerb]

I have a 1990 and from what I could gather it was laid up for Rogers by Howard and we all know how they build them.

Thanks to you all so far....Mabe it was set up with an i/o from the factory. I have all reciepts from the original owner and in 93 they installed the whole package engine and drive for 10,000 at lucerne marine up by clear lake......I think it's clear lake.
As for selling it on craigs list......we'll see. I was checking into just getting a larger cat (daytona) but the wife likes this boat more than me I think.???
Mabe old rigger can jump in hopefully....thanks again guys...

Nothing could be further form the truth. Why on earth would Roger let the then new owners of Howard lay up his hulls let alone touch his molds? He's forgotten more than Gene will ever know about fiberglass.

707,
Your hull will handle just about anything you throw at it. As far as expecting the King Cobra to handle it I don't know. The man you want to talk to about that is Joe Rhodes, he runs a shop out in the valley called Rhodes way (or Rodes Way, I can't remember for sure the spelling of his last name). He's the man when it comes to setting up that outdrive.
When OMC introduced that drive they were tring to recover from the bad Cobra unit that came before it. They wanted to set a record in a boat to help promote it. We built a boat at Advantage to go after a record in the ETII class, and got it at 118 and change (I think. The record still stands so it wouldn't be too hard to get the exact speed) The outdrive was bone stock except for a low water pick up, and Joes installed that. It was one of the only things we never had a problem with. Oh, we set the record with a single carbed SBC.

Roger Weiman has, as his boat of choice to enjoy in his retirement, a 20 like yours, but with a jet. ;)
I was working for Roger when we brought those molds back to the shop. I will have you know I spent more days than I care to remember in them color sanding and buffing to bring it up to snuff. Great boat, and I like the deck on it much more than the Spectra deck.

[Squirtcha?]

Geez that things in great shape for being 20 years old. It looks all original too.

Is that the boat that they raced down the Mississippi with? I seem to remember a Banshee with a King Cobra doing that? I was pretty young though.

[old rigger]

Disco,
yeah we raced that 2 years in a row. 1000 miles in 2 days of racing, balls out on the mississippi. First year we got a big fat DNF, second year...1st place.:)
Raced Parker enduro, flipped and sunk in the first turn. lol Tore the left sponson off the boat. Stripped it, and sold it to I believe a guy in Texas. He wanted to do the glass work and use it on the water again.

Thanks for the info, I stand corrected.

Old Rigger...thanks for the info...So was this hull from hallet molds?? I will try and get in touch with Rhodes in the valley. I rebuilt the outdrive last year myself filled it up with redline and have been beating on it ever since.....no problem with it yet...
So what would be the most bang for my buck? It is a bone stock untouched 454ho. In my old flat i head some head work done installed a roller cam set up and changed my prop to a two blade and gained about 25mph. Should I toss on a aluminum manifold and mabe a cam first? Mabe a set of aluminum heads....What would you do......thanks for all of the info....
Here are a few shots of my old flat...I sold it to a guy in vacaville and have never seen it again. It took me about 2 years to completly go through the thing. It would go over 100mph on some glass......That's pretty rare at berryessa though.....thanks again

a couple more

No, the boat was a Conquest but not the same Conquest that Sleekcraft became. This was a few years before that. I'll be damned but I can't remember the guys name that owned Conquest, he was a gel coater too and I worked with him at Warlock. He was not the regular gel guy there, that was Jim Sullivan, but this guy would help out now and then. He was also selling some molds at that time too but it was a little tunnel deal.
I don't remember how Nick Barron came to own the molds, maybe he just bought them and never did anything with them? I dunno.
