Hello everyone first post here. I have a 2021 198p with the manual jackplate and a temptest 23p. I do not know anything about the jackplates. Once I have the boat loaded I’m spinning around 5700 and only getting 53mph. I was wondering how to go about starting to test heights on the jackplate and just what set ups you guys are running and what you are getting for speed and rpm. Let me know if you need more info to help! Thank you all!
