    Z521C/250 Pro XS numbers

    What are you guys seeing for RPM’S and top speed out of your 250 Pro XS on a Z521C? I have a 2018 and wanting to compare what I’m getting to what the average you guys are getting out of them. It would run 70-71 last season and this year I’m only seeing 65-66 at 5780-5800 RPM. Load is comparable as far as tackle/fuel and such

    68-71 anywhere from 5650-5900 depending on which prop I'm running. 521c with 2 stroke pro xs

    Worked fury 4 24p and worked 25p tempest plus. Can only turn the tempest plus in cooler weather. But I've seen 71.5 out of that prop

    Thanks for the info guys. I switched to lithium batteries and thought I’d gain 1-2 mph so losing 4-5 mph was surprising
