How do I know if my core is good?

A core is good if it does not have any broken aluminum. Broken aluminum is usually the result of a bearing on the rod disintegrating or by a part of the piston breaking off and wedging between the big end of the rod and the crankcase. By turning the engine upside down, you look for cracks in the paint on the cases especially on the bottom and exhaust side. The condition of the sleeves, pistons, rings, rods, bearings and oil seals are all included in the rebuild.

What is included in your engine rebuild?

The engine basically includes crankcases cleaned and painted if necessary, crankshaft is completely rebuilt, cylinders bored and honed to the very next size possible to ensure that there is room for over sizes in the future unless you are at 1.00mm. in this case there will be other options needed to rework to usable condition (mainly re-sleeving), head and head cover. The 781, 785, 787, 800 and 951 Sea-Doo engines do not include the RAVE valve guillotine assembly. The Yamaha Rave valves are not included in the engine rebuild, but you will send them in and we will inspect them for wear and replace them as needed at additional cost for the part only. We will also include the upgraded safety link and make sure they work without binding.

Do you test the engine?

Our engines are tested case and waterside pressure leak down is tested by installing our custom block-off plates on the engine and measuring leak down rate times. Compression is tested and verified to be within the OEM specifications with a specific pressure test that expands the rings in the cylinder for maximum accuracy. As a result, a compression test is not needed with this procedure.

Sea-Doo 951 had a design flaw in the flame arrester that sucked in water. Sea-Doo issued a service bulletin and fixed it by putting deflectors on the flame arrester.

Sea-Doo tried to cure this by putting a boot around the joint. 2001 and later models have an o-ringed joint.
