I have stock 22p mercs from the factory on my 2018 35' with 350s. 63-64 normal here in Michigan, 64-65 last fall down south normally. On it best day 66 light on fuel. I am only turning 6000 though. Very low prop slip. If I over trim it to get rpms up the speed falls off. So i am having a set of bblades made up for me right now with the hopes of getting the rpms up to the limiters as well as carry the bow a little bit more too. In a prefect world if i have the same prop slip numbers with yrhe new props and 6400 rpms its 68 on paper but i know that wont happen lol. However if i can run a solid 65-66 when i want to I would be pretty happy. I built the boat for cruising, not speed, and this thing is barely sipping fuel at 47-48 only burning 35 gallons per hour. Slow down to 45 and its 30 gallons per hour and slow down to 40 and its in the low 20s.
