I think the Webra 50 and Irvine 53 are great 40 size two strokes for profiles. The TT 46 Pro is also a good engine at a reasonable price. The Webra and Irvine will run you around $125 - $145 new. The new Webra Speed 55 looks like it may be the new 40 size powerhouse. I just got one, but it is still in the box. It weighs the same as the Webra 40, and is advertised to have almost as much power as a 60. The bad news is it costs almost as much as a YS 63.[:@]
