Conversion & underwater hardware for a small block ChevyThis is a typical list of hardware for the Crackerbox. The Crackerbox was originally designed as a race boat. These boats did not use transmissions or any shifting mechanism; it was turn the key and go. Because of the short length of the boat, it is difficult to use a transmission (13" additional length). In order to keep a reasonable shaft angle (15o or less), the motor must be moved forward and/or the rudder installed on the back of the boat. One local builder was able to use a Velvet Drive transmission and still maintain a 12o angle by using a motor with a "low profile" oil pan. The installation listed below is "typical", i.e. no transmission and normal underwater rudder. If you would like to use a transmission, substitute Item 99-231 for the 99-000 Bobtail Conversion Kit. A Transom Rudder Bracket is often used to move the rudder aft in order to accommodate a transmission or reduce shaft angle. The prices below are meant for estimating installation cost only. Prices are current as of March 2006; check the Price List in the "Inboard Hardware" pages to confirm prices. Additional items: motor, hose for exhaust ports, steering, throttle control, and gauges. |

* Specify degree/length ** May want to use 90750 POL ALUM @ $50.50 ea *** The chain coupling is the most common and most desirable way to hook up to the prop shaft when not using a transmission. If this option is used, deduct the 90793 flywheel power takeoff from the conversion kit. A less common method is to use the flywheel power takeoff plus item 90864B (1") flange takeoff. The flywheel adapter bolts to the flywheel and has 4 holes to which the 90864B bolts. The 90864B accepts a 1" prop shaft. The flywheel installation requires the motor to be higher in the boat and is seldom used. |
