New water pump kit and pressure is good. I got in some weeds at Holiday day before. No debris in lower as I replaced water pump after Twok trip. I am thinking that I should just go ahead and get replacement stats as they are 10 years old.

Tommy was out of stats last week. Went to Hubbard Sunday and ran from Yankee to the old bridge at 5200 revs with no problem. I am just going to replace the 10 year old stats when I can get them.

i hope they aren't as high as the ones for my 2014 Pro XS. They are right at $200 for both plus tax. Was gonna just change them myself until I heard that. Took it back to the dealer and let them fix it. Boat was gone a few days but it was fixed under warranty.
