[QUOTE="Johny25, post: 303995, member: 7791"] I don't think the small resistance you are explaining is causing you to lose speed....... as for your speed readings lets get some more info from you because 22mph with that setup does sound low. What did you take your speed reading with? What is your RPM reading at WOT? What size prop do you have? And does the motor sound like it slips (revs higher) while you are running it? Mark the rubber hub inside the prop before you go out next time and when you pull out of water check to see if the mark is still in line with the prop, this will tell you if prop hub is slipping.
