Does anyone have any experience using a 2.40 gear reduction on the 20B? I am going to use the Marcotte PSRU only because he has a much higher  HP Rating and it is only offered in the 2.40 ratio in the configuration I am using. However I notice everyone uses the 2.85 more commonly. Is there a specific reason why this would be better for the 20B?. I would appreciate any input any of you might have to offer.

Kind Regards
Tom

Turbine, not impeller. You know what I meant. :)
