How hot does a waterbox get?
Last summer I blew an exhaust coupler from overheating. I *might* still have a waterflow problem but it's hard to tell with no hard temperature info in the manual. Running on the water hose in the driveway it runs frosty cool with a strong flow out the "pisser" but to me it looks weak running in the lake. Engine seems to stay cool but the exhaust pipe & waterbox get sizzling hot. I've used a temp gun on a few. I will see around 100* depending on the model. http://www.facebook.com/twinlakesjetskirepair    '89 Kawi 650SX 42.4 GPS  +3" stock pipe, ported ex. manifold, drilled waterbox, blueprinted pump, Ocean Pro ride plate    '99 Yama GP1200 65U 61.8 GPS  ported cylinders, matched cases, milled head, blueprinted pump, long ride plate    '96 Seadoo HX 717 53.13 GPS  light porting, massaged cases, lightened flywheel, port matched manifolds, Rossier pipe, stubby pump cone  Thread Information Users Browsing this Thread There are currently 3 users browsing this thread.
