Looking for a tech willing to do this for me in mid-michigan I have the js300 and a working 750 sitdown. If you know anyone please have them give me a call 8102231264
Lol that statement makes no sense, so you're telling me the 750 with the 300 pump will cavitate but the 701 with the 300 pump won't?Don't waste your time. You'll get so much cavitation if you don't use the right parts. @j0hnny is right! You will need a bigger pump or else it will just cavitate! Rather than swap out the 750, Drop a new 701 in that JS300 and call it a "Yamasaki", Ha!
