I have a hydramaster 323. 23 horse with a tuthill 3006. I'm wondering everyone's thoughts on replacing the 36 with a 45. It would cost $2500 - $3000. Is it actually worth it? I've read many threads with lots of mixed reviews on the difference between the 36 and the 45 with most are saying getting away from the 33 is most important but not a huge difference from 36 to 45. Thoughts?
