Hi All

I'm sorry if this isnt the most appropriate place for this post but I thought you guys might be able to help me.

I am building a hovercraft and have purchased a 250 cc 2 stroke engine (the ec25 by fuji robin). It is rated at approx 20hp.

I have heard rumors that this is the same as (or a variant of) the ec25 used by polaris in a number of their 2 stroke 250 cc models.

Can anybody here confirm whether or not this is the case.

Why I ask is because perfomance parts are readily available to increase the performance of the polaris engine to in the vicinity of 40hp, whereas parts for the juji robin (even basic parts like pistons, gaskets etc) have all but died out.

Thanks so much in advance for your help
