Loving these old ski rebuild videos, keep it up!

[@toddreid7660]

Glad you two are safe and well keep up the good work. Thanks for all the videos and the inspiration of your time and effort to restore older seadoos.im restoring a 97.5 grey ghost 👻

[@Kyle0228]

Great production level, really enjoying these Sea Doo series 👍

[@darrenellis8910]

Great clear and to the point tutorial 👍

Glad it was helpful!

I’m buying a 951 so need this next video to come out lol

I'm rebuilding two engines so I need it too lmao

SBT wear rings are really good. At least for my ski

[@Andingo86]

Ok thank you. I'm doing a 951 engine soon. I missed you

[@grh317]

Carb bolts neat trick :P

[@georgehoy2038]

Great Teardown Video. BTW if you are wondering were the Needle Bearing came from, The vid shows it came from your workbench on the end of your magnetized screwdriver

[@TodayWeWrench]

No shot. The bench was cleaned before disassembly like every single time I do a tear down. This engine has caged aftermarket bearings in place and was never ran after the top end rebuild. That bearing was from that engine when rebuilt.

[@antoineyerna9371]

Hello, good to see you back. I'm just rebuilding my carbed 951 what do you suggest for case sealant? Seadoo Manual says Loctite 518 for carb engine and Loctite 5910 for DI engine. Does it really make a difference? what are you going to use? Thanks

[@Bmxjoe26]

Great video love the SBT hate. Lol. I had a new SBT starter last half a revolution before the armature shaft snapped. But I will say if your gonna make sure people call engines engines instead of motors you should probably call bolts bolts and not screws. Lol. Keep up the great work.

[@stevenbirou2890]

Great video guys these x4 hull videos help me out so much on my ski I’m still wondering tho are you guys going to do another x4 build?

[@rvega91722]

Hey Guys its mid June and we are still waiting to see the rebuild on the 951. Do you guys know of any mods to get more juice out of them. I have a 98 gsx limited with a 951

[@TodayWeWrench]

Assembly video will be out in a couple weeks

[@Garethuk2006]

Do you need to cover any of the shiny crank bearing surfaces before it goes for blasting?

[@thediplomasta5891]

Not if they will be machined afterwards. They should know to avoid blasting those areas; the professional blasters anyway.

[@thediplomasta5891]

Instead of "Nick #2", you should go by "120 pound Nick". 👍

[@toddreid7660]

Nick #2 said you guys were both covid free what has happened to you both no more videos.I really enjoy my wet Wednesdays 😉

[@farmerap4431]

Any advice on these 951 would u overhaul them or swap out with refurbished 951

[@toddreid7660]

Hey guys hope you're still safe and no relapse.but need some info on where to find the larger fuel for a 951 motor

[@bobkane880]

Question, the motor alignment tool, is there just on size, or multiple? I’m a newbie but damn you guys make this shit look easy

[@solarguy22]

Is there a way to remove the starter bendix without pulling the engine? Or because of the probable need/desire to change the bearing, it has to be pulled?

[@jadd9328]

What kind of compression are you getting after a rebuild?

[@TodayWeWrench]

Factory spec unless we’re milling the head or going aftermarket

[@dovilerukiene4573]

Hello, where the green hoses connect to? Thank

[@silviuntro]

Hey great work, I just got a 2002 seadoo gtx, I don’t have a key and the engine is locked up, please send some input this way.I have plenty of car mechanic experience but I don’t want to rebuild it until I get a key so it would actually turn on..please help.

[@TodayWeWrench]

You have to find someone to program a key for you

[@ReddyPowersports]

What oil will you be running ? Amsoil interceptor ? Seadoo xps? Or what oil do you recommend for these engine ?

[@thediplomasta5891]

NOT Amsoil! It was not approved tcw-3! That is the ONLY oil that you should NOT use for 2-stroke! I'm a Certified marine mechanic, for 22 years, if that adds any weight to my statement. I care about your boat, the same way your vet cares about your dog. You should listen to me.

[@ReddyPowersports]

@@thediplomasta5891 I hear ya, what oil would you recommend?

[@thediplomasta5891]

@@ReddyPowersports for 2 cycle oil, they're all the same (marked TcW-3). Synthetic oil, will leave slightly less carbon behind. But if you do a good seafoam/powertune/Ringfree (they're all the same) treatment on a regular schedule, then that carbon won't matter. In the old days, there were wild differences in performance between 4-stroke oil brands. But as they have all independently worked on a better formula over the years, the gap in variance has closed to a small difference. (If they are all really working towards the best possible design, then theoretically they should all eventually end up with the same formula). 2-stroke oil offers no performance improvements. It only offers the continuation OF performance. 🤣 But only certified tcw3. And there's only one I know of, that is not certified but also still somehow available for sale. 🤨

[@jonariopaz5381]

​@@thediplomasta5891Hello friend, come see some of your videos, I would like to know if you can help me find a seadoo xp 951 in good condition, I like this jet a lot

[@mx1209]

Can these be run in a dry exhaust configuration?

[@TodayWeWrench]

No

[@Andingo86]

Would you recommend using a impact wrench on the flywheel or no?

[@thediplomasta5891]

No. It will damage the threads on the puller tool bolt.

[@jadd9328]

I’ve got a 951 that over revs on the trailer. It idles fine in the water but when it’s on the trailer it over revs and I have to choke it to kill it. Any ideas on what Is going on. I was thinking air leak in the fuel system but not sure. GTX Carb. Thanks

[@maratkhakimov8663]

Hi bro. 951 di It seems I forgot to pour oil into the balance shaft during assembly. Can I do this through the nozzle hole? Are the balance shaft bearings lubricated with this oil?

[@rlyle5804]

You can do it through the nozzle hole and the balance shaft bearings are lubricated with this oil. I used to check mine every year. It is a PAIN.

[@lukesgoproch8019]

What starter would you get

[@tomdonahue4224]

Out of curiousity, how tough is it to get a 951 out of an XPL? I about lost my mind putting Beach House Sponsons on one about 20 years ago.

[@ryanjohnson8340]

Any chance you can post a video rebuilding 951 carbs

[@garyc3955]

emailed these guys on their site about rebuilding my 951, never heard back, .......

[@TodayWeWrench]

Check your wear ring

[@rookiethomas]

@@TodayWeWrench the wear ring is fine the problem is not that it does not move. the problem is that it does not accelerate as if it were drowning. Do you have any other idea what it could be I would really appreciate it brother

Where are all the 951 go fast parts??? Ebay is a bust

[@davidtopj5538]

Hey there watched one of your videos while back and you recommended these guys called Full Boar Online. Do you still recommend them? I sent them the top end on a 787 to have bored completed with a top end kit and I can't get a hold of them by phone number or email. They don't return their phone calls or emails. And so I have no idea if they're even open for business. But they have my parts....

[@fckurvtc]

I sent mine to them yesterday. I shipped mine with the signature required. Did you?

@@fckurvtc not sure, i had my shipping department send it. I have the tracking number which says it was delivered.

Yes I called ups it was signed by someone at the UPS store where the private mailbox is held.

@@fckurvtc did you ever talk to them on the phone or by email and get some kind of a time frame? Cuz every time I tried to call, so no one answers and no one returns my call or my emails. So I don't even know if they're in business?
