ENYA 25 SS
I have a used Enya 25SS that was in a Wonder. I was wondering if it is BB or not. I took the front housing off but still cant see any bearings. Do I have to pull the crank etc. to see them?
Also, I see the nice testing done on the Enya 30SS. Can I assume that the 25SS will give somewhat simiar results?
Does anyone know if there is any test results for the Enya 25SS in a thread somewhere.
Thanx for any info.

Post #8 in this thread, 25SS AAC 9x5 jxf prop at 13,600rpm peak on 15% fuel. This is on the stock SS muffler. 14,300rpm on a OS 25FX muffler, which is probably larger in volume.
If your engine is a BB engine, there will be a raised "snout" on the front of the engine right behind the prop driver. BB engine:
Bushing engine:
This is on a *bay ad, and its hard to see the front of the housing, but if you look carefully you can see the engine doesnt have the raised bump for the ball bearing.

The bushing engines tend to run a few hundred rpm less than their BB counterparts, generally. Based on the SS25 AAC numbers from above on 15% nitro, It would probably be 300-400rpm less on 5% nitro which is what they should really be ran on.
