PTP Measurements on 618 Pro

[mkm]

Wondering what the ptp measurements are for the ones that have a 618 Pro with the new Mercury 4 stroke 175 pro xs? Mine is walking pretty bad and I've read about seat time, trim and raising motor. My PTP measurement is 3.25" (water pressure is 20-25) and wondering if I need to try raising any? Still breaking in motor so haven't gone wot much, other then what it says do in the manual. I already know I need to work on my driving skills for this boat.

Also, I have a 24P Tempest Plus with the med. vent plugs and holeshot is slow when I have another person in the boat, spinning up to 3000 rpm. Would it help any by removing any of the plugs since its a 4 stroke?

I have the 175 ProXs with a Tempest Plus 23 on mine. It is set at 3.50 ptp, that's where it came from the factory, and runs great. Holeshot, handling, and 65-66 mph is what I'm getting since 2011, don't see any reason to mess with it.

Most run 3.25 to 3.50. I run a tempest 24 and 3.25 is the sweet spot (15psi) on mine. I haven't heard of many people running higher than 3.25 on the 618. I have 2 medium plug and 1 removed for holeshot. They do seem to run better with more weight in the back.

So I raised the motor 1/4" to 3" ptp. Drove alot better. WOT at 3/4 trim was 5400 rpm, water pressure 25, 64.4 mph. Past 3/4 trim, it starts walking. Wondering if I ought to go up another 1/4". What y'all think?

If you fish any rough water you might want to stay where you are instead of raising it more. I Fished Sam Rayburn recently on a rough water day and I can’t imagine what it would have been like if I was running any higher. If you have a hydraulic jack plate then by all means go ahead and dial it in. If you have a manual jack plate then consider best possible setting for all types of water.

Thanks, I raised another 1/4 and tried it and I didn't like how it felt. Lowered it back down and am done messing with it.
