    Gary had .48 p/s on Monday, Sept. 9. Back in the day, guys would run the .48 p/s in an engine so they could race C Stock Tunnel in NAMBA.

    RE: Dumas Hawk picco .21

    You can make rear sponsons from insulation foam, 1/16" plywood. That boat was designed to run with rear sponsons.

    You could run a .28 in the boat. The only problem might be the engine...

    RE: 21 Tunnel Talk

    I am running 11 oz. of lead in my VS1 - 1.5 oz. in each sponson tip, 4 in front of the radio box and 4 in back of the radio box.

    The O.S. 21 Outboard will not pull a X445 and a X642 might be...

  12. RE: AQUACRAFT'S NEW MISS VEGAS U-18

    The OS 18 CVR MX will drop right into the motor mount. The pull start should work fine. Personally, I prefer using a starting belt and my electric starter.

  15. RE: Requesting advice on completing Sk Daddle 40 kit

    I would recommend you consider spending the money to upgrade the drive system to a flex cable drive system. However, the cost of that might be more than you paid for the boat.

    Are you planning to start one engine backwards to get left and right prop rotation or are the outdrives reversed?

    RE: 21 Tunnel Talk

    The O.S. 21 is a better engine - it holds all the 21 tunnel class records.

    But, some guys still run K&Bs. Just not the guys winning national championships.

    RE: K&B Outboard

    You are correct about the starting direction. A good prop for that engine is an Octura X440 or a Grim Racer 40/53. The Dumas Hot Shot Sprint wood kit is a good choice if you like to build. The...

    Looks like a Sundowner Outboard Hydro. Back in the day they were very poular in SoCal. That's going to be one loud engine with the straight exhaust.
