i need some in put on avenger hulls are they good ,are they a fast hull
-
I think they were owned by CeeBee and mainly a ski boat I have no clue if they were built to crazy fast
-
Pics will help as Cee Bee built diffrent kinds of hulls . I heard they are good lake boats . I dont remember them breaking any records though , but then again I cant remember shit as it is .

I have a 16' avenger and I am gonna find out how fast it is this coming summer! I think i finally laid hands on a rotary Turbo out of a mazda! We will see what she will do!
-
Add a little squeeze to it and you'll probably piss off a few big block fans :o
-
I have been told and seen a couple videos that lead me to believe that I can SMOKE a well built big block with the Rotary! I have a guy here in Austin Texas who is gonna go through it and says that he can get 800 Horses before the juice! Thats all on pump gas and weighing next to nothing!
-
Granted it wont scream out of the hole. But on a 20 stomp Ill smoke em all if I can keep her on the water
-
I would like to see how it works out.
Since the rotary doesn't produce much torque but likes to spin, what would be the best impeller to run?
-
I am checking on all that. i do know that i wont get a hole shot worth anything but I should realize my powerband around 5800 rpm up through as high as 12000! I will have to build boost first. Just something to play with.

Bobby Brown that owned/owns Cee Bee, is one of the pioneering guys in jet boats and high performance boats in general. His brother owned Powercat boats back in the 50's in Paramount. When the company moved to texas, Ray Ledger gave his brother, Bobby Brown (half brothers I guess?) a set of molds to stay here and go on his own. That was in the early 60's, maybe 62 or 3. With that mold he started Avenger boats. He knows his shit and his boats did compete and win races. The 16 you have is probably a splash of the old 16 tahiti though. Post up some pictures.
I'm sure you've all seen this video on youtube. A good running wankel set up right is gonna run circles around most other jet boats, big or small block. I don't know shit about rotary engines, but wish I did after seeing this clip. You have to watch it til the end to get the full effect of the acceleration this thing has. Amazing. :o

I really like those motors. Back 15 years or so ago, there was a RX that ran at the drags that was wild. Ear piercing RPMs at the launch and flat got with it. Unbelievable fast for the day.
A buddy of mine just competed down in California in the 24hours of Lemon, (not Lemans. google it) and they used an RX7 and ended up 3rd out of 90+ entrys. The thing was fast and dependable.......
I did hear once that with the dual spark plugs if the timing wasnt right, the motor would have a tendency to run backwards.........cool O0
-
With rotarys there is a leading and a trailing plug and coil , if you don't do it right it will run backwards!
-
I dont think you are gonna turn that impeller 12k rpm let alone 5800 with a rotary, Unless you decide to run a Z impeller...Those motors work well in small cars and build power high in the RPM range. You wont make the power down low where it counts in a jet though IMO.
-
perhaps someone on here can remember where that clip of a rotory motor in a jet just flat left another jet boat....I'm looking for it but can't seem to find it....damn it's the shi#s getting old......
-
old rigger has a link to it in his post about 4 above this one, top link ;D

You obviously haven't watched either of the videos in those youtube links above. :D

Damn Fork I really must be getting absent minded.....thanks... :D

i need some in put on avenger hulls are they good ,are they a fast hull
My buddy own's A 20' Avenger out board ski boat it run's about 70 + great boat if you like out boards.
-
Avenger Boat were very fast in the 70's. I think both Dan Durham And the Barons ran record braking Avengers. Dan I think switched to a Rogers But I'm not sure I'll have to check my old pictures.
-
I'll have to check my old pictures.
tom....you need to start scanning those in....i'd love to see all of them.....i wouldnt mind helping either.
-
Brad we'll work on that. The Rotary thing is an interesting side bar to this thread. Let's see couple it to a lenco 5 speed or a 3:1 gearbox... And Didn't those mazda's run opposite to American engines in which case the gear box would be mandatory. The concept to make that project work I think is to take Colin Chapman's (lotus) theory that speed is made through making it light and put that puppy in a very light but very stiff hull. Good luck
-
Durham and Barron did run Avengers. Also the drag Boat the Devil was an avenger. Most Cee Bee / Avengers for the general public I think had more of a traditional deck with windshield etc. while the race boats had a racing / river type deck.(http://)

Looks like #6 cylinder has an issue, cool looking race boat though.
