V-Drive?

When you are around this stuff on a regular basis, you neglect "v-drive" just isn't a family phrase. Serveral boats in our catalog are v-drive boats... meaning they've a rear-mounted inboard motor, with a standard prop shaft. Obviously, if in case you have the motor at the again and the shaft exiting the boat ahead, there needs to be something between. That one thing is a torque tube (drive line). A gear field that adjustments the path of the facility. That gear box is a v-drive, so referred to as, as a result of there's an angle between the centerline of the input and output shafts. That angle is usually 10 or 12 levels.

Since most ski or velocity boats under 20' are hurting for room and perform higher with much less weight, they do not use a transmission. For that reason, v-drives can be found with forward solely; ahead and impartial; or forward, impartial, and reverse; and with various gear ratios.

So why put the motor in the again, shoturl.org and have all this additional hardware? Performance! Our Tornado and Thunderbolt designs are being raced at speeds over one hundred mph. Center mounted engine boats often high out within the 60 to 70 mph vary.

Hardware "what's-its" for inboard installations

In case you are unfamiliar with inboard installations, the selection of the proper parts is commonly troublesome. For the novice, we recommend our book, "INBOARD MOTOR INSTALLATIONS". The following is a description of the assorted components. Their perform in an inboard boat. Confer with the "V-Drive Installation" sketch above to find out the location of the parts listed beneath. Although the sketch depicts a v-drive installation, a direct in-line drive can be related from the v-drive aft.

#1. QUADRANT or Custom TILLER. A quadrant is required when cable sort steering is used. The custom tiller is required when single push-pull cable steering is used.

#2. RUDDER Post BRACKET. The rudder put up bracket supports the upper portion of the rudder. To forestall the rudder from falling by way of the underside of the boat, a security collar is used on the rudder above the rudder post bracket.

#3. RUDDER STUFFING Box. A rudder stuffing box prevents the water from getting into the boat via the rudder shaft hole. Various types of seals or packing glands can be used. It's advisable to make use of the identical kind for the rudder as for the shaft log (9). The packing-sort gland may be repacked whereas the shaft is within the boat. The seal-kind requires that the shaft be removed to substitute the rubber Neoprene seal.

#4. RUDDER STUFFING Box PLATE. The rudder stuffing field plate goes on the outside of the boat. If you have any kind of questions relating to where by in addition to how you can employ boat hardware - Highly recommended Webpage,, it is possible to call us from our own web-site. It is non-obligatory and often not used on the faster boats. It does present a strong bolting. Bearing for the bottom portion of the rudder stuffing field. 5. RUDDER. Rudders of varying dimension. Shape are listed to suit almost any small boat. RUDDER. Rudders of varying size. Shape are listed to go well with almost any small boat. Rudders of various measurement. Shape are listed to swimsuit almost any small boat. Rudder Shafts (1" or 1 1/8") have to be matched to the rudder stuffing field, collar, and rudder publish bracket. 6. STRUT. Struts are available in various angles. Drops to match your installation. STRUT. Struts are available in varying angles. Drops to match your installation. Struts can be found in various angles. Drops to match your installation. Drop is the space vertically from the bottom of the strut to the centerline of the strut bearing on the aft finish of the strut. Two kinds of bearings might be obtained for most struts. The Aqua-Lube is a fabric type bearing. The BJ is a rubber-kind bearing. Is recommended when the boat is to be utilized in silty waters. Strut bearings are replaceable.

#7. WHIP STRUT. Whip struts are used to stop deflection or whipping of the shaft in high speed boats with flatter shaft angles.

#8. FIN. The Custom "V" FIN has a vee in the bottom to fit the vee in the underside of most boats. The STREAMLINE FIN has a flat base. Is often meant for smaller boats. The 2 bigger fins are used with the highest pace inboard boats.

#9. SHAFT LOG. The shaft log prevents water from coming into the boat through the shaft hole in the underside of the boat. Shaft logs are available in various angles to match the shaft or strut angularity. Refer to three (RUDDER STUFFING Box) for information as to the types of packing gland.

#10. PROP SHAFT. Shafts are available normal lengths as noted. Shafts might be lower to any desired length. Keyed on the driving finish without extra price. As an example, we can lower a shaft 63" and also you pay for a 5'6" size. Overall size could be decided by measuring from the coupling in the boat to the aft finish of the strut, and including 5" for 1" shaft, 6" for 1 1/8" shaft. Some ski boats use a shaft that's tapered on both ends. The prop finish is a normal taper, the engine finish shouldn't be. We want further info to taper this finish. There is also a further charge for tapering the engine finish of the shaft.

#11. PROPELLERS. For throughout use, the three-blade typical-sort propeller is mostly used. Direction of rotation should be specified. Direction of rotation of the prop is as seen from the again of the boat trying ahead-left hand counterclockwise; proper hand clockwise. All propellers are meant to fit our propeller shafts and have commonplace 1" tapers.
Propeller application chart for various manufacturing boats.

#12. PROP NUT Kit. A prop nut equipment furnishes the components essential to securely hold the propeller on to the shaft.

#13. Split SLEEVE COUPLING. The sort of coupling is used to connect the propeller shaft to the v-drive output shaft when each output shaft and prop shaft are 1" in diameter.

#14. V-DRIVE MOUNT AND V-DRIVE. V-drives can be obtained that embrace integral forward, marine parts neutral and reverse gears. Others include forward and neutral, whereas there are those who haven't any reversing or marine hinge neutral place. With the latter, a marine fitting transmission should be used on the motor. The exception to the latter assertion would be for full race functions. Ratios of the v-drives will vary. If in doubt, specify the kind of boat, its purpose, pleasure or race, the dimensions of motor, and preferably the diameter of the propeller to be turned or the house obtainable for the propeller. We are able to then estimate the ratio required.

#15. V-DRIVE TAKE-OFF. A v-drive flange take-off is used to couple the higher shaft of the v-drive to the torque tube. Check with TORQUE TUBES (#16) for information regarding sequence #1310 or #1350.

#16. TORQUE TUBE. Torque tubes are used to couple the motor to the v-drive or a jet pump. Two collection can be found, a #1310 and a #1350. For extraordinary use with the typical pleasure boat and motors to approximately four hundred cubic inches and a torque tube 24" or shorter, the #1310 series is passable. For bigger engines and for high velocity use, the heavy obligation #1350 sequence is fascinating. Note that the motor energy take-off and the vee drive take-off must be of the correct series to match the torque tube. The torque tube does have "play" in the spline that may make the torque tube approximately 1" shorter or longer than the noted dimensions. If a length other than those listed is required, the torque tube might be cut and sized to your specs. Check the worth listing for cost of this service.

#17. TORQUE TUBE GUARD. A torque tube guard protects the boat. Occupants if a failure ought to happen anywhere along the torque tube assembly. Ordinarily, these are fascinating on any of the higher pace boats with torque tubes 24" or longer. Note that these are made to accommodate each the #1310 and #1350 torque tube collection. (See #16.)

#18. Safety COLLARS. Safety collars are used on prime of the RUDDER Post BRACKET (2) and in excessive pace craft simply aft of the strut or ahead of the shaft log as a security device. Either cut up or conventional collars can be found.

#19. Power TAKE-OFF. A energy take-off connects the motor to the torque tube. The Series #1350 or #1310 must match the torque tube. Drives can be found for taking the power from the entrance end, the flywheel end or from a marine transmission. Most often, the drive might be from the flywheel end. In many circumstances, driving from the entrance end is impractical with motors outfitted with harmonic balancers or these with small diameter crank shafts on the driving end.
