bottom blue print begins

started with many mesurments, settleing on removeing the rocker from the center pod from the transom 6 ft forward. Using the outside sponsons as the baseline as they are straight for about 7 ft. Cut a section from the front half of the pod, so at 6 ft. There will be a step. Will need to fill the last 2.5 ft with as much as 3/4". thats my question, what to use to make up that gap as it grows moving toward the transon???? Center pod will end up flat from the step to transon.

Something for you to think about, Back in the early days of Mod-VP (80-85) i was told of a Sleekcraft trick. I involved sqeezing the air in the tunnels. They added a wedge to the tunnel ceiling to promote transom lift. I don`t know how long it was but there must be some Sleekcraft devoties out there that would know.

hey db. That would'nt be that hard to play with, after we test that might be something to try. My guess is with this change, there will be considerable lift, and needed with 12" set-back and 500 lb of motor. Godd thought..................

Those tunnels are realy shallow at the front. I can imagine that the "trick" DB is telling about should work well. The fact that the tunnels are deeper in the back than the front will probably result in too little compression and lift.

I`ve never driven one myself but have been around several Sleeks way back when. Those suckers were hung high and i mean HIGH! The Misty Blue Mod-VP racing team had several with support from the maker and tried many differant bottom mods and the tunnel wedges were one of the biggest improvements. The other was removing the last 10 inches or so from the outside sponsons. I don`t remember exactly how high they went with the cut but Marvin Catrette told me the cut made top end speed greater but would also bounce in calm water.

That sounds like a good idea. does anyone have any old Mod VP pics of this or know of anyone who ran a sleek back in the day?

You may want to try and send "BuddyRoe" on here a pm. His Dad was at one time the main guy racing for Sleekcraft and had all the right bottom mods done to his boat including the one above.

hey varmint, drill some holes 1/2" in the transom to get an idea of the condition of the wood inside. Near d rings, engine mount holes, drain plug. If its not clean wood, then its time to think doing a little more exploring. And you are right about the guys on this board, great information and it allowed me to put the puzzle peices together. Good luck with the project!! Gb
