2014 merc 175 pro xs model 1175p73ey serial 2b110355p. I’ve been reading the sticky’s about water pressure and all. I have a champ 181 with 6 inch manual jp 24 pitch tempest plus and have found the best performance height adjustment. But I am not confident in the water pressure that I have at this setting. 10/11 psi at wot. Personally I would be more comfortable with higher readings. I have to lower it enough to get higher psi that it hurts it on the top end. My question is, is there a negative to installing the mercury high speed scoop kit on my lower? If so, what might it be. And what amount of psi gains can I realistically get as a positive result? Thanks for any help in this matter. Have a great day
