I bought this boat a while back at a swapshop. It came with a K&B 3.5OB. I am wondering what it is? It is made of epoxy glass and is 27" long and 14" wide. I know it is not a Prather Lap Cat. I hope the pics help. Also did anyone run it and how did it perform. Thanks for the help.Les

Les..
That is the original dumas fiberglass hotshot...I owned one in early 1980's and with a stock k&b 3.5 o.b. ran rather well..
I also had the k&b auto trim system installed that adjusted the outboard trim angle while cornering...hope that helps..
 
Thanks for your help. Did You run a hopper tank as well to assure fuel flow? Also are the newer ABS Hot Shot sprints a lot faster than this boat?
 
Never ran a hopper in any tunnel boat and never had a issue but I always mount the tank as high as possible..I learned that from R/C airplanes...the hull would run well with the K&B SS or SX engine....with a worked x440 prop...both have the external exhaust...and a little engine port work should be an awesome runner...the newer ABS hull is lighter so I would expect that hull to be faster...but I never seen one of those run....I have built the shorter Hotshot Sprint wood hull that runs fine but is not really made for higher output engines ...and from what I have seen and experienced is ...any hull can win a race....but you need to finish...
Les I hope this helps... Is the hull already joined together...if not..be sure the bottom of the hull is square to the building table otherwise a twist or warp will be introduced...use slow setting epoxy with a filler and don't be afraid to use a lot of it....if I remember the radio box is built first and glued in place then the top deck on top of that.
 
Thanks for all of the really great help. Our lake is solid right now but I will be able to run it by the middle of April. Happy Holidays and Best Regards, Les
 
Les,

The boat you have "MIGHT" require a turn fin.. you can probably ask Dumas for a build manual. I bet they still have copy's.

Let them know you have an old Hotshot Glass boat and they might be able to help.

Grim..
When I race and built the boat..no turn fin was required...the sponsons on the bottom has a lip that extends below the sponson..that aids in stability...
Oh I asked Dumas several times about popping out a new hull for me....no deal...
 
I still have the Hot Shot from almost 40 years ago. In fact, I have had another brand new kit in my closet for the last 35 years that I am building now. I like the sort of scale look but the cowl does not resemble any of the open cockpit tunnel of the 70s. So I made a mold and pulled a cowl for it.

The boat is not competitive today. With a JG20E or a X440, the best it can do is about 35mph. But it blows over a lot when running into even a light breeze.

I am in the process of molding a pair of stepped sponson bottom and will require some surgery to lower the tunnel, reduce the angle of attach and add some dihedral.
