When I am under way the prop does not sound smooth. There seems to be turbulence, or so it sounds like. When originally I tested the motors in the lake by just holding on to them, the performance was poor. When i took the prop guards off they were fantastic. So it seems a Kort nozzle is good but a random tube around the prop may be bad?</div><div id="yui_3_16_0_ym19_1_1466558752449_2646" dir="ltr">Hank</div></div></body></html>
