This unit has been developed to meet a requirement where high torque, lower r.p.m. than direct drive is required. It is particularly suitable for marine applications where driving a large propeller at lower r.p.m. is very efficient and quieter.

The unit is powered by MFA/Como Drills 800 or MFA/Como Drills 850 series 12v d.c. 3 pole motors, with heavy duty carbon brush gear and double ended 6mm drive shaft. The motor is mounted on a rugged 1.5mm steel right angle bracket. The 2.1:1 reduction is achieved via two precision aluminium timing pulleys utilising a high quality toothed timing belt. The final drive is delivered through two block mounted precision ballraces with a 6mm keyed steel output shaft.

The RE800 motor version will deliver around 1229 g.cm torque (0.12 Nm) running at maximum efficiency.

The RE850 motor version will deliver around 1380 g.cm torque (0.14 Nm) running at maximum efficiency.

Output shaft speed on 12v (800 motor): 2300 r.p.m. approx.
Output shaft speed on 12v (850 motor): 4000 r.p.m. approx.

Recommended marine propeller: X65 - X70 or similar brass propeller. Marine coupling available (6mm-M5 thread). Part No. 1105/51.
