RE: prop for patriotxl
Speedy,
Either the SJ-90L or the BSE-90L will work well. Both have nearly identical performance. Its more a preference of appearance and wow factor. However the BSE do sometimes come up 200-300 rpm more than the cast case.
A few folks have told me they were running 11x9 props on the SJ-90 and patriot with very good results. Two were located at relatively low atltitudes (NC and LA). One gentleman in South Dakota run a 10x11 prop.
Attached is an image of one XL without the inlets, SJ-90L up front. Looks nice.
