For all scale fan`s
Our scale NXT drivetrain was developed on the basis of the modern Z-drives, which are mostly used on the original boats. We also adapted the anti cavitation plate which ensures for original boat that the propeller can not suck in air. This Z-drive convinces through highest processing using the highest quality materials. Thus, this boat drive made of powder-coated aluminum cast includes eight steel ball bearings and four hypoid-toothed bevel gears. This ensures optimum, quiet mileage and a long service life.
This model drive is universally suitable for electric or combustion engines with up to 6PS. The output speed is 7% higher than the engine speed. Suitable for boat models from 1.30m length.
The gluing of the flex shaft in the powerboat drive is omitted since the NXT has a square inlet. This stern drive can be used both right and left running. The choice of the flex shaft determines the running direction. The inclination of the Z-drive can be adjusted horizontally by +/- 7-11 ° and vertically by +/- 3 °. Here, the vertical adjustment is done manually by means of the integrated set screw. Horizontal adjustment may be done by using a 2-3mm linkage (bicycle spoke) or throtlle set (not included). Suitable for this are servos with 25-30kg holding power, which are also not included.
Good to know!
The vent screw, located on the top of the drive, can be used to assist in the event that two NXT drives shall be connected. Optionally, this can be done by a 3-4mm linkage and M3 or M4 ball heads. The rubber sleeves and the shaft seal are available as a spare part on request.
The drive must be filled with gear oil before usage (see Downloads). Please also note that the drive should only be used in water - therefore not in the dry state. Otherwise, the drive will not be sufficiently cooled and shaft seals may be damaged.
> Do you have any questions concerning this product?
What spacing is needed if I want to use two of these drives?
The space between the drives should be 82mm (3,23").
Is this Z-drive steerable?
Yes, all of our Z-drives are steerable but it has to be done by you. You could work with a 2.5 - 3mm bicycle spoke for steering from on side only or with our sterring set #1833 for steering from both sides. Besides that you will also need a 15Kg quarter scale servo.
Which height shall be used for assembly?
The prop shaft of the drive shall be 2-3mm above the keel line
