Yamaha 650 701 760 1100 1200 Wave-Runner-Blaster Super-Jet Crank-Shaft-Seals RTS

  It comes complete with all of the seals necessary to freshen up your crankcase.  If you have an older motor / engine, its always a good idea to change the crank seals as part of your preventative maintenance. Air leaks can develop over time through the crank seals and can cause a lean condition and develop serious motor damage.  Leaking crank seals can also cause many symptoms of bogging and stalling leaving you thinking there is something wrong with the carbs or electrical.  There are times when those components are not the problem, it is the crank seals.  If your not sure of your motors history or if you want to know your seals aren’t leaking, then we always recommend installing a fresh set of seals.  These crank seal kits are in stock and ready to ship.  We also have the Threebond 1211 case sealant and complete gasket kits available in our ebay store.
