Does anyone know where I can get a template for making a motor mount for Rotax
engines?

Thanks,

Bill

Don't think there is one template for all. Is it inverted? Upright? Usually there
is a base plate mounted to a frame of some sort. What type of installation is it?
Tractor? Pusher? Let us kow and someone will have something for ya.

You can download a pdf engine data sheet (with mounting stud dims) for
the 503 at http://www.800-airwolf.com/R503.htm .

The 277 has bolts spaced at 70 mm front to back and 96 mm side to side.

However, I would have a plate and a motor together and try a template
made from cardboard for the first try to make sure the plate/bars clear
the rather close proximity of the fan and shroud.

The same goes for the 503 if usding a C box, or a belt drive with a
large casting.

The other parts or the motor may interferes with the plate/bars,
requireing some relief be provided.

Another option, not as good, is to use longer mounting studs/bolts and
space the motor away from the plet slightly.

More than a 1/4 of spacer, and I would not be satisfied with the design
personally.

I have seen stacks of washers used as spacers in this situation over the
years and it is really BAD design.

Tall spacers should be a solid piece of stock to assist with shear
loads,,,,,,,,,,,,,,,,mark

BTW, the 503 is 153 by 94 mm spacing for the mounting bolts.
