Rocker bottom set up

Greg, after reading your post in the jet boat section about my boat (73 Eliminator) I would love to get some more info about this hull.

You said I shouldn't remove the keel fin, well it doesn't have one. Do you remember what type of fin it should have ? And where it should be ?

Also you said not to run a droop snoot on this hull, is there a reason why ? It had one on it before (when Busby owned it).

I have had a lot of problems trying to find any info on how to set up this type of hull (rocker bottom). It has a set back pump/shoe/ride plate + the outer plates, I'm using a JC pump for now and the old (long) diverter.

I was told this hull has lots of bow rise, and the outer plates need to be set slightly down, and the ride plate about 2 or 3 deg up (it has a tapered shoe). I was also told to not set the motor back but to move it forward (not a problem, I'm only using 2 seats) to help keep the bow rise under control. I guess the idea was to use the outer plates and forward motor to control the bow rise and porpoise, than at speed it could rock back on the ride plate and air out . Does this make sense ?


Sorry for all the questions but you are the first person I have found that remembers these things

Jeff Has some one taken the rocker out of this boat? Rocker is just like a rocking chair as the bottom goes to the transom it rise's up like a rocking chair. If it does not have a keel fin install it 52 inches from the mouth opening of the intake.The plates we installed even on the outside and about an 1/8 below o.n the inside of the plates. This was a good starting point and mods can be made from this setting.

Greg, I don't know how much rocker it had when new but here is a pic of how it looks now. The story is, the bottom had been done by Tom Papp when the intake was set back. There is no spot under this boat that is flat, it is one big curve from the tip of the bow to the transom ! You can even see how the stringers were cut curved on the bottom. In a 4 foot length from the transom it has about 1/2 inch of rocker.



You might remember this boat ? I was told it was owned by Bill Coyle, it was metal flake Green and said "Image" on the side ?? I was also told it had an Olds 455 and JC pump when new.

This was Bill's boat before I owned it.

Tommy helped me by doing the bottom and setting the pump back. The bottom is still original, with exception of making sure that it's strakes were perfect (clean w/ no knicks), still has the rocker. Never had a fin though.

here are 2 pics from around 1999 - 2000 during it's switch to a BBC from an olds:

i run my fin at 53 inches from mowf opening. turns like a summbitch,Ive thrown the ol lady clean out the boat more than wunce. it hangs a little fin on a mean azz pass which looks tough when everyones watching.

Cool ,thanks for posting those pics Brian !! I have been wondering what it looked like green, you were right it was fugly !! Let me know if you find any others , I would love to see them !!

I've got some that I have to scan in and post up, pre-digital days ... I'll get them up soon for you
