    4 strokes are hard to read. Best way is to get an AFR gauge

    I've been told you can't really read plugs. If you are worried you are burning lean, get an AFR (02 sensor) setup.

    That's just what I've been told....

    Correctly tuned rec boats with EFI should almost always come out with white plugs. Lean motors also get white plugs.

    EFI tuning has everything to do with adjusting all of the few hunderd or so fuel tuning points that the motor gets to on a spirited ride. It takes a wideband and a data logger to get it right.

    OK, what do I need and where does it go? is it something that's plug and play? specific to seadoo or any gauge....Again, thanks for help and replies!!!

    Theres a "how to section" on this. You need to buy a gauge, most of us are using Innovate MTX-L. Pull the exhaust mani and drill and tap for the o2 sensor. Mount the gauge in a mirror with a pod. What do ya know, I sell these!!!

    OK, so this is basically a permanent installation deal? not just a test or check deal?

    yes is permanent. if you dont want to do that just add 42lb injectors and a intake and forget about it. me and thousands like me have that setup and is very safe.

    Yes, I've been told that many times...turns out I have 48's as stock, why would I put in 42's? (the boschs don't fit besides) I need to know they are being told to open more, or longer, or however it works...

    If you really have 48's, your lean problem is none existent. Your super rich!
