    1996 Yamaha Wave Venture 700 Exhaust Hose Issue

    I have a perfectly minty 1996 Yamaha Wave Venture 700. I have had the ski a couple of years and have now replaced the OEM 63N-14752-30-00 exhaust hose twice because of a tear... Ski runs great for nearly a year and then the exhaust leak happens.. Ski is running great, water flow and temp is very good..

    Has anyone else had this issue with these hoses tearing often and creating an exhaust leak? If so, is there a fix or better option that you may have found?


    Thanks!

    Nate

    Since the Exhaust Pipe is double-walled (i.e. Dry Pipe), most likely the annular cooling space is blocked/clogged with sand/pebbles/gravel mostly near the Stinger Section which is getting hot thus baking/killing the rubber Exhaust Hose.

    Disassemble and clean the entire Pipe till you hear no more rattling coming from the cooling passages and channels.

    A wire coat hanger and a soft rubber mallet will help dislodge and shake out all the gravel.

    Remember to clean/clear all the Cooling Lines and the Brass Hose Fittings also.

    My GP1200 Pipe had about of pound of Gravel in it...

    Thanks, JC! The thought of a cooling issue crossed my mind.. The side pisser is working well and I felt no excess heat on the engine or head pipe. But, your example makes sense.

    Yep, on the old Yamaha 2 strokes that style pipe is known to clog up that internal water discharge in the stinger that JC pointed out. Seems to be the only thing tat will cause a bad exhaust hose on those?

    Thanks! I ordered two new hoses just to keep a back up on the shelf. I plan to keep this ski indefinitely because it is a very nice machine, with ample power from that twin carb 701. Way more power and fun than I expected for such a large hull. I plan to pull the ski form the lake, remove the exhaust and clean it up as you two suggested.

    Thanks again!
