    Gp1200R Jetworks mod -mod??

    Hi,
    I am sure this is not a new concept..although I couldn't really find this exactly - so I am hoping for a bit of help.
    I have a standup background and the jetworks flow control mod feeds the water in a little different way AND to be truthful I am a bit nervous about removing the stock bilge "system" - Just in case.

    I bought a Jetworks mod kit which, unless I misunderstand the concept, basically states to modify/block the exhaust water routing, remove the bilge and mod the pump to feed the water to muffler via a flow control valve.

    My thoughts are that, to retain the bilge, I could place a 3/8" T in the lNEW ine back from the exhaust and feed the water back to the muffler via the flow control valve. Therefore, I wouldn't have to remove the bilge.
    It makes a bit more sense with my hand scrawl (refer attachment)- maybe....

    Questions are is there enough pressure - will it work??

    Thanks Mal...

    OK, kudos for drawing it all out... if I am understanding your idea (and forgive me, but I've done my FC mods a bit different) you want to run the FC valve off of the T? I've tried something like that before; you will not get enough pressure from the muffler cooling to open the FC valve and you will melt your stuff in the back.

    If you are just wanting to keep your bilge, invest in an extra through hull fitting and run your line off of the pump in through it, leaving your bilge pump alone.

    Like I said, I think that's what you are wanting to do, based on my understanding on the FC mod.

    if I am understanding what you are saying... no, not enough pressure

    to retain the factory siphon bilge, just add another thru hull fitting (3/ in the transon above the factory bilge thru hull

    Thanks. Having not working on these pumps before - is there a thread for this?
    eg: I assume that they need to be drilled and tapped for like other Yam pumps?
