Engine Mount System
If someone were to design the ultimate engine mount system for mounting an engine to a square 2” tube, the criteria list might look something like this:
This engine mount, just might match that criteria.
- Strong: 6061 T6
- Lightweight: 3.2#
- Versatile: Can Do Straight Mount… 2° Left or 2° Right… 2°Up or 2° down
- Adaptable: 277, 377, 447, 503, 532, 582 Model 90 or 582 Model 99
- Easy to instal: Pre-Drilled mounting holes on 1” centers
- Allow access to engine bolts
- Cost effective
Spacer Pads (4 pcs.) - Rotax Straight Engine Mount Bars (Front and Rear… Flip Rear Over for 582)
- 2” Square Boom Tube Mounts (Left and Right)
- Rotax 2° Angle Engine Mount Bars (Front and Rear… Flip both over for opposite angle)
The Rotax Engine Case Mounting Bolts are accessible through access holes cut into the Boom Tube Mounts which are large enough for a standard socket to fit through to tighten, check or remove the engine bolts. The 12” long Square Boom Tube Mount has cross holes drilled every inch from 1” thru 11”. Engine Vibration is dampened using the 2200 Series Barry mounts. (not included)
Aluminum Spacer Pads which are .125” thick are sized for use between the Barry Mounts and the Boom Tube Mounts to achieve a 2° slant; up or down. They can also be used to simply raise or lower the engine location in relationship to the Boom Tube. The Slant option works independently to any Bias (angle) option.
(Image Above) A 447 Rotax engine is sitting in the Engine Mount. It's currently using the 2° Engine Mount Bars. The innovative bars will accept any 377, 447, 503, 531 or 582 Rotax engine. The bars are a simple design which makes adaptation for other engines easy. They are ambidextrous for either Left or Right Bias (angle). Simply “Flip” them over. The Origin of Rotation is the Theoretical Center of the Rotax Engine Bolt Pattern in both the X and Y axis. Slots are machined into the rear Mount Bar for adaptation to either Rotax bolt pattern. “This versatile design allows the Angle Bars to be replaced with Straight Bars for an engine mount which faces directly forward. On the Straight Mount Bars the rear mount has offset holes. Offset holes forward for the 377 or 447 then simply “flip” it over for the 503, 531 or 582.
