I recently bought an Eyra SP but everything that could be upgraded was upgraded to where there isnt much difference between my boat and the regular Eyra. Only differences are the one I bought has one bilge pump, no lighted compartments, and 36 gals vs 52 gals of gas. And it looks like I can add more fuel storage but honestly dont need it.With the 225hp I can get up 74mph loaded down before I get scared and back off to a comfortable 70mph cruising speed
