I’m getting 5200 – 5300 rpm with my 25. Hoping a 23 can get me closer to 6000. Thanks January 21, 2021 at 11:49 pm #134 EdHawkinsParticipant Yep, too much prop for the HP. A guy I know had the same problem with 150 with 25. 23 is best for 150 to 175. Author Posts Viewing 2 posts - 1 through 2 (of 2 total) You must be logged in to reply to this topic.
