I'm trying to figure out what to do for an engine. With Rotax 503 being in short supply, I'm not sure of my options. I'm building the 1650 EROS. So I'm wondering what engine you have and if you're happy with it or wish you had something else. Also, any suggestions?

Thanks,

John C

[face=Arial][/face]I'm about 75% complete on a 1600R and I'm presently working on the engine conversion.  I'm going to use a Briggs and Stratton 993CC 37 HP generator engine in a direct drive / hand propped configuration.  Installed engine weight should be under 88 lbs including oil and exhaust.  See details in this thread:

I used an MZ202 engine in my Eros. Very impressed with the engine & the performance it gave.

The engine was built in Canada by Compact Radial, but the business was later sold to the Chinese.

Here is a link to the Australian dealer: https://aerochute.com.au/upcp_product/fiate-mz202-replacement-engine/

With a bit of research you should be able to find the Chinese company, & buy direct from them.
