All,
So I just had my 2014 RT188 replaced under warranty. I now have a 2019 RT w/ my old 2014 Mercury Optimax 115 hp. I took it out for the first time today and could not get max RPM’s or speed. I have a brandnew Spitfire X7 SS prop 21 pitch, i should be getting 5800 to 6000 rpms at 45-48 mph. Never got faster than 33 mph. My hole shot was slow, also when i engage the throttle and putting it in gear, i am not getting any power till i get half way down to open it up. There is something definitly wrong here. In the old boat, i had an aluminum 4 blade 22 pitch prop and was easily going 44mph @ 5600rpms with an excellent hole shot. Any ideas what it might be?
