after reaching 2000rpm, I get no additional thrust or speed. engine sounds great. I do hear some grinding of some sort in bottom rear. I can leave shifter untouched at 1500rpm and it will climb to 5500rpm in about 3 seconds agian w/no additional speed.<br /><br />I was told the prop was bent reapaired prop = same problem<br />I was told cables need adj. fixed cables = same problem<br /><br />Any suggestions?
