This was pulled from a running 1998 Seadoo GTX 787.  The computer indicated around 200 hrs of run time.

At some point thought the top end was rebuilt / replaced.  It reads .5mm over and cylinders measure at about 82.8mm

Compression tested @ 140 psi on both cylinders.  

Bottom water cooling passage cover is not included. Two of the bolts broke off holding the cover on, they aren't next to each other so you can leave them be or drill and tap for new ones.  What you see in the pictures is what will get shipped.

Cylinders have some dark spots presumably from sitting for an extended period of time but don't seem to cause any problems given the excellent compression numbers.  

Domes are in good shape but cylinder head cover has some corrosion on the inlet / outlet water ports.

This is a fresh water motor.
