    WRA700AV flush kit install

    Hello All,
    I want to install a flush set up on my 1997 Waverunner 700 (WRA700AV). I figure there must be a way to "T" into the water lines, but I am not sure what lines to use or tap into. I can't find a diagram showing the water flow thru the engine or where the water enters the block. I found where 2 lines are connected with a plastic "90" fitting that could have just been a solid line, there is no reason to have that 90.... And it looks "factory" to me. The flush kit I got is a 90, with the a short hose and the connection for the garden hose. The other end of the 90 is a short piece of hose that needs to connect somewhere?
    Any help would be appreciated.. THX

    slower lower Delaware. And have a cottage on finger lake in upstate NY.
    Scoober, on the 650/700 motor the flush hose screws into the exhaust. On the exhaust there is a plug screw (#16 in pic) that needs to be removed and flush hose installed there. Looking at the ski from behind it would be on the left rear corner of the motor.

    The flush kit you should have looks like this one in pic under the listing for your ski on SBT.
