I have a 1997 XP... My winter Project is restoring it to all original (OEM). I bought it with a blown engine it literally had a blown out case by the the balance rod where the gear meets the Crank. It had LITTLE to no oil in the case and hull.. after i diagnosed, it the oil pump had failed! Ive been researching over the last 4 months on how to rebuild the motor, I know how to do it just buy reading the manual, but i LOVE Visuals! THANK YOU for this! this is the BEST VIDEO on youtube for the 787!!!! this will help me when i go to reassemble once all my parts come in.
WOW thank you for the nice comment! Stay tuned the next couple videos should help you and the community out a lot
By far the best set of tutorial videos for the 787. Outstanding job.
just pulled my 787 today and found this video. exactly what i needed. thanks!
Thank you guys!! This video is detailed and professionally made. I am rebuilding a 787 rfi right now.
Glad it helped!
By far the best 787 rebuild vids!!
Thank you!
This video is excellent. Tons of information packed into the video, and no nonsense! Thank you.
Beat video out there. Can’t wait for the re assembly video.
Thank you so much! We are trying our best to put out quality video that helps others in the community.
@@TodayWeWrench I’m sure these will pick up quick in the jet ski community.
This tutorial is Top Notch!!! Nice job!
thank you!
These videos are legit. Nice work man
Thank you!
Love the shirt! Keep up the great work man!
Thanks bro
Great videos!
Thanks!
I must say you have an awesome looking shop bench and floor!! There is no way I could wrench on something that nice looking!
I’m getting prepared to tear into my 787 (previous owner said it didn’t have any spark and that’s why it doesn’t run) I hit the button and hear “clunk” and can feel the starter is making that sound… unfortunately if you try to put a pipe wrench on the drive shaft it does not budge either direction… I’m thinking locked up motor…
Sounds like its locked and will need a full rebuild
@@TodayWeWrench dug down into it and PTO piston seized on wrist pin, stator piston scared all up on the side... amazingly? The rings are on both pistons and head looks good... going to pull it the rest of the way out and crack the case... can't wait to see what's inside.... kinda like Christmas morning when you've been bad all year long!
Many thanks. The best I've seen so far. I don't know how to thank you for it
How can I check the seals without having to assemble the whole engine first ?
Pressure test the RV housing. See our assembly video for that
I cant find a flywheel puller for 787, link doesn't work, whats the puller size and thread side 38mm Right hand thread? thank you.. Love the content
once it's blasted don't touch it with your hands the oils from them cause fish eyes
thanks bro helped out alot my guy.. have a question tho so im looking to reinstall oil pump since when i got my 95 xp they did the block off on it im trying to get it back to factory new ... should do a video on that and your thought on taking out the pumps
I would leave the stock pump in place and replace all the lines. You can see how to install it if you watch our engine rebuild video
I did a 787 jet boat build and was not able to properly mimic the gravity feed oil injection so I deleted it.
Do you know if those engines CIRCULATE crankcase oil or does it just kind of sit in there and never circulate?
The way I have it it just sits in there since the injection was deleted but maintained the lower case hoses with oil and im feeling like every few years Id like to somehow suck out the old oil and put in new...
Hey question, I’m going to run a ball hone through the jugs of my 787, the question is what size of ball hone should I buy? I’m assuming there are different sizes?? Thanks
Big info...
How did you hold the crank to get the flywheel nut off
This crank was stuck but if your engine is spinning over freely, stuff a rag in the exhaust port of one of the cylinders before removing anything on the top end.
If engine is already pulled apart you can also put a pipe through the rods keeping them from turning over
@@matt.squarebody5427 No you will risk damaging the rods. If your going to replace the crank assembly its fine but if you are going to try and reuse your crank, reinstall one piston and one cylinder wedge a rag in it to safely bind it.
what size taps did you use to clean out threads. all sizes please. when I tried this, I was removing metal
Strange, what sizes did you try?
I have a problem with extremely high compression in my 787. One cylinder at 150psi while the other one is at 270psi?! I don't think it's the gauge because 150 should be perfectly fine.
Great video, where is the best place to buy the parts for the top and bottom end?
All info is in the video description

Hello sir I just have question I have got sea doo 3D with 787 rfi its 2004 and it hasn t run long long time so hove much does it cost to rebuild it ?
Thank you
What Milwaukee drills are you using?
How much oil do you in the case? Before you reinstall the top end. For the crankshaft
1oz
Got a part number for that crankshaft o ring? Mines torn
Which o-ring? The one that goes in before the PTO?
Can you pull the flywheel without the puller?
No
@@TodayWeWrench ok thanks
