    Place Diverter, without hesitation. I like the manual levered one, but the hydraulic one is nice also, just have to get used to how fast it moves IMO...

    talk to Tom at JBP performance. He will turn your JC pump into a split bowl for much cheaper that buying a new split bowl... I am new to jet boating but they say the JC bowls have good veins! check it out.....freakin bad azz. http://www.jetboatperformance.biz/ca...plit_bowl.html

    You got a Great Jet already (12jc) for your application , however as indicated the "Bang for Buck" upgrade is hands down Trim package (diverter) , instant gratification ,definatley worth some mph and ride/handling improvements Lots of other ideas here on the boards ,little things and hints to help your Hot rod be fun and dependable Call or PM if we can help Tom

    Then IMHO run it the way it is, a loader won't hurt you, but the "seat of the pants feel" (aka the Ass-O-Nometer ) may be dissapointing for the effort..

    I say run what you brung for now, I would bet you will find plenty of stuff to spend money on...without building the pump to tighter tolerances, most bolt-ons yield minimal results, just my .o2c...

    as stated above i am semi new to jet-boating. I bought a diverter and a new loader from Tom......and with no shit i probably gained 4-8 mph....never been gps'ed but i think that is about what it is, i guess i do have question though. If i sent you my JC and got a split bowl with snoot or droop snoot......do u think i would see any mph gains? I hate to say it but i am still running with BOW tanks. what kind of SHIT is that?
