INSTALLATION INSRUCTIONS
The installation instructions for this package on a Rotax 915 series engine are very similar, so please refer to the instructions found on that product's page. Any product installation differences will be added below the link. Check them out before you start so you do not go too far or do a step that is not required.
Differences are the exhaust outlet.
Once you have completed step # 4 of the 915 installation instructions, complete the following.
Since the 916 has a movable exhaust outlet rather than a fixed outlet, everyone's outlet will be slightly different; therefore your cutout will be slightly different.
Below are the steps required to custom fit the angle you want your pipe to exit the cowling. The more vertical the outlet the easier to remove and install the bottom cowling. It will also create the most drag and..... as compared to sloping it back. If you slope it back too far you will run your exhaust into the cowl skirt which you do not want as it is required for cooling. Find a happy medium that you are happy with and loosely clamp your exhaust pipe in place with the V Clamp provided after step one below. Check the engine manual for current torque on final installation.
I recommend having the other side lower cowling fit and screwed or clecoed in position before doing this as you do not want the nose bowl to move. Having the cowl skirt fit and drilled is also good as it holds the bottom flat when fitting your cardstock and can be held in place when positioning your exhaust pipe.

STEP 1:
Tape cardstock paper to C channel and locate screw holes.
STEP 2:
Use a scissors or razor blade or knife to cut the cardboard till you have an even 1/2 inch clearance all the way around. If you cut too much out, not a problem.
STEP 3:
Last chance to modify the angle of tailpipe. Too large a gap on aft end or front end.
Tape cardboard in position till you have what you want.
STEP 4:
Cleco your template to the cowling. Mark your hole cutout 3/8" smaller than what you have on your cardboard and mark the same size as your cardboard. The cardboard is not as stiff as the aluminum and there will most likely be a difference due to positioning. Trim to your smaller hole on the cowling (pictured below). Position cowling and trim a little at a time till you have a 1/2" gap between the exhaust and the cowling. Verify that the exhaust does not hit cowling after first run and first flight. Trim as required to keep from hitting.
Lh side lower exhaust opening is now done till first run.
