JET DRIVE INSTALLATION MODEL SD-309 |
| These instructions apply to transom angle of 8 degrees
and from 3/8 to 1” thick and dead rise angles from 0 to 20 degrees. If
your mold has a greater transom angle a wedge can be clayed into the mold
to correct the angle. INTAKE CUTOUT The intake cutout dimensions are shown on EXHIBIT A. TRANSOM CUTOUT An initial cut-out is made in the transom to allow the intake to be installed. See EXHIBIT A. INSTALLING INTAKE There are four 3/8 – 16 tapped holes in each mounting flange that is used for jack screws. These screws allow for setting of the intake to the proper angle. An intake setting fixture, that bolts to the rear of the intake, is available to set the intake the proper distance from the transom as well as a means to check the correct angle. a. Set the intake in the hull with the four jack screws installed. b. The bottom center of the intake at the front of the intake must be flush with the bottom of the hull at the front cut-out use the jack screws at the front of the intake to hold your setting. c. Using the jack screws at the rear of the intake to move the intake up or down. Set the machined surface (where the pump unit bolts) at 4-5 degrees relative to the keel. d. Check the intake to insure that it is level with the hull side to side. e. Tape around the perimeter 1 – ½” from the cut-out. (This makes your epoxy job look much nicer.) f. Mix your bonding compound according to the instructions. Place the compound around the cut-out and also the mounting flange of the intake. g. Set the intake in the hull so the jack screws come in contact with the hull. h. Double check the intake setting. i. Smooth out and fare in the compound to the tape line also smooth out the compound on the bottom side of the intake. j. Remove the tape. k. Wait for the compound to kick-out. l. Drill the mounting holes with a 17/64” drill. m. Counter-sink the drilled holes for Flathead Machine screws. (From the outside of the hull.) n. Use bonding compound under the heads of the machine screws to make them water tight. Install screws, washers, and nuts. o. Mark and drill transom mounting holes. p. Mark and drill cutout holes. q. Complete transom cutout. SPECIAL NOTE: If you are using a HIGH-PERFORMANCE INTAKE you must follow these steps to insure the ride-plate centers up with the bowl. a. Bolt the ride-plate to the intake. b. Bolt the jet-unit to the intake and to the transom but do not tighten. Use the gaskets provided. c. Set the yoke on the ride-plate. d. Move the jet-unit side to side to line up with the ride-plate and yoke. e. Tighten jet-unit and transom flange bolts. |
