Details:

This is a 1996 bombardier 787 engine. Pulled from a 1996 Sea Doo Xp. Starter is bad but feels like it has a very decent amount of compression when turning over by hand. This could be a great deal if you are looking for parts engine or just to fix up.

The only major problem I can tell with this engine is when trying to pull the exhaust manifold one bolt striped out. The ski I bought ended up being too expensive to make a repair worth it.
