xprop vs dynafly vs concord ( which solas impeller to buy? )

[stevethegas]

hi,

im looking to replace my impeller as its very worn and bent/dented ive got a 98 gtx linited 951 i should be getting 60mph but im guessing the prop is causing me problems and top speed is 49mph and top rpms are 7000 the gauge shows 8000 being the top

so the two questions are what prop should i go for ?

and will the prop cause me to be 10mph down or should the revs be higher ?

Just for reference, I have the 1997 GTX with the 787cc motor. My top, peak speed is listed at 62 mph. I bought a Solas Concord last year, that dropped my speed to 54mph. So, I went back to the stock impeller and last week, I was hitting speeds over 60. It's not always the impeller, but the wearing ring might be a problem too....

i should of mentioned ive replaced the wear ring for oem part and the motor has a fresh rebuild also been running premix but just relised that ive been putting too much oil in around 28-30 ratio instead of 40
