We ill contact you when the engine or machine work is ready. We can take credit card by phone and ship the same day unless otherwise discussed.
The core is your old engine that you remove from your machine.
No. Our program is designed to only rebuild the motor you have and most times you will have to change everything else aside from having possible fitment problems. If we let you to upgrade, we would only have the smaller engines that are less popular that nobody will want in inventory.
If you do not have a core, we help you to find other alternatives to a PWC Engine. Other companies, such as OEM dealers and salvage yards, etc..
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.
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.
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.
Yes, most of the manufacturer colors are matched but they are not always match able. We do try to paint them to match your original color scheme in this case.
All of our engine contains new pistons, rings, rods, bearings, seals and gaskets. The pistons are WSM's line and we include using factory rings from RIK Japan and factory Crankshaft oil seals by ARS Japan. If you buy an engine that uses aftermarket low quality seals, it may make their warranty, but will not make it long after the warranty expires. This we have seen with the competition many times.
We charge for broken and cracked cases, sleeve damages beyond boring and cylinders at 1.00mm, as all holes will have to be re-sleeved and set to STD bore. The welding charges for broken aluminum and cylinder damages will require you to send photos to firstname.lastname@example.org. We will evaluate the damages and reply with the estimate
Please call us for pricing.
When ordering an engine or crankshaft outside of the US, you must present us with your old engine first. When we receive, any damages will be assessed and we will notify you of the amount money for the wire transfer or US money orders for the sale. All freight, taxes and duties are YOUR RESPONSIBILITY of the customer. Please see our International Sales Policy for more information.
Please remember, we will charge additional fees for damaged aluminum, missing parts or aftermarket parts. Once we have received both the core parts and the payment in full, the order can be released for shipping. For additional information please see our Core Exchange Policy.
You can calculate your shipping rates and transit times when you are ready to send in after you get your final weight including the packaging. Go to ups.com or fedex.com.
Please see our Warranty Policy page.
Call us at 866.870.1121. Do not disassemble the engine or return it to PWC Engine without filling out the Warranty Claim Form or writing to us at . Also, it would be helpful for you to read the instructions in your owner's manual.
Please see our Core Return Description page.
We recommend Oil-Block off plates for use on engine rebuilds on skis with normal use. Common failures on engines include lack-of-lubrication seizures due to failed oil pumps, breaks in lines, leaks, etc. Running a pre-mix gasoline will help eliminate this problem. We will include instructions with your rebuilt engine for the mixing procedure and break in
Nothing. PWC's engine comes with gaskets like OEM that do not require any type of sealant.
Gaskets, Never! O-rings while not recommended by us, but if just replaced can sometimes be reused if in usable condition.
We always recommend factory oils, please refer to the owners manual for the exact type for your machine.
You will need a factory service manual for this procedure or you can write us at email@example.com. Please include Year/make/model and we will reply. If you are send your engine into us for rebuilding, we will remove and reinstall after rebuilding.
Take the battery out of the ski. If you have filler caps, remove them. Use of an automatic charger with a 2A cycle is recommended, otherwise use a trickle charger, following the guidelines in its instruction manual - you will need to monitor the specific gravity of the battery during charge if you do so manually.
Doing mods even to factory engines substantially decrease the reliability of any PWC. Doing any type of modifications will void the warranty.
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. The 951 also had a problem with the joint between the exhaust manifold and the exhaust pipe. If it did leak it would onto the carbs. Sea-Doo tried to cure this by putting a boot around the joint. 2001 and later models have an o-ringed joint.
No, and we do not recommend it as these engines are already mostly at the manufacturer limits stock.
