Great work man. Question. If was getting ready to buy a 96 speedster, twin 718 in winter and traveling 3500km to see it. What should I be looking for on inspection. Any help is appreciated.
love your videos. very informative. i have a 2005 Seadoo sportster le di with the 951 and it has a charging issue. i "think" the only thing left is the stator to be tested/replaced. Suggestions? Can it be replaced without pulling it out of the boat? Thanks in advance for your help
Did you check the rectifier ? Un plug it and see if you get high voltage at the battery. It could be just a bad recitfier or bad battery. There is also a fuse for the charging. See if that is good as well. If all that is bad then changing the stator can be a challenge. You need to remove the exhaust to get to the front of the motor to remove the stator cover. Oil lines and cables will be your challenge.
I have a suggestion for an upcoming video. Can you do a maintenance guide on how to keep these boats running great? I just bought a 2003 SeaDoo Sportster LE Di and I am new boat owner. Any advice will be greatly appreciated.
I will. We are just in the process of getting the seadoos and boats in the water. I am going to review each one..check top speed and performance and the required maintenance.
Your videos are great! Any suggestion on how to clean the engine bay? Can I just pressure wash everything or do I need to block off some areas such as the air intakes for the carbs? I just picked up a 2001 Sportster SE that needs work. Mostly cosmetic and hopefully the engine will start with out too much effort (currently locked up for some reason). Your videos will be a lot of help!!
I cover any open ports. (for example if the plastic air box is off the carbs) and then I just pressure wash everything . It works amazingly well. (spray nine works wonders as well)
@@SeadooRefurb Thanks for the quick response! I took the pump off yesterday and removed the spark plugs to see if I could turn the engine, but the shaft won't turn. I tried forcing the pistons down through the sparkplug holes - nothing. So I am guessing that the engine is ceased and I need to pull it. I will be paying very close attention to all of your videos on the 947/951 motor!! Thanks again!
Great video. Just got a 97 gti. Look like same engine. I think it seized. But im not getting any response from electronic either. New battery. No beep from key, just oil warming light come on for sec, then nothing. How u test module?
6:35 I deleted both oil pumps on my 05 Ultra 150 & 98 SPX 787 for that reason right there. Those oil pumps are garbage. Those oil lines fall off so easily with these 2 stroke personal watercraft/jet boat engines. Running premix will save you a lot of headaches in the future. Sucks that yours was an error made by a mechanic, but those pumps are bound to fail anyways.
Yes ..Pre mix is a 100% security that you are getting the right amount of oil. Having said that...I have never had even 1 bad oil pump. All the failures we do to people not doing a correct assembly of parts.
@@SeadooRefurb That’s surprising. Skis with triple engines are famous for blowing up a cylinder for that reason alone. After seeing it happen to many ZXI 1100, GP1200R, & GP1300R models I wasn’t taking any chances.
@@tehsnipatres208 Ya...I hear what you are saying. For me ...We have lots of people riding and all it takes is one person to go fill up at the gas pump and then I am toast !
What are some common reasons a 2003 Seadoo Sportster LE DI wont turn over when starting? The boat will crank but not turn over. The boat has sat for 2 years with no fuel in the tank. Battery has been replaced about a month ago and about a gallon of fuel was added to the tank. What should I look for to get the boat to turn over?
I am unclear on crank and turn over. to me..they are both the same thing. if you mean the engine is turning but not starting then you need to start with the basics. check compression. check for spark . if both are good then dribble a small amount of fuel in each cylinder and see if it fires up.
I both a 951 2001 i know there a pain to get out had 150 psi both cylinder i made the commitment. Took it out for ride then engine lock up after 10 minutes: guess other guy that rebuilt it prob got those oil injected hose not connected right. Winter project now. Any place you recommend parts in Ontario?
I have never had to replace one before. It should be quite a simple thing to do. Removal of the old one will give you all the insight you need to install the new one. :)
@@SeadooRefurb thank you for your reply however my boat had the previous one removed. Any chance you could show where they are usually installed? Thanks!
I have a 2001 sportster Le I want to rebuild the carburetors. Any suggestions before I begin? I made the fatal mistake abusing regular gasoline and I think the carbs have got clogged. I got a lot of smoke when out on the lake. Running too lean Any of your thoughts before I begin would be appreciated Thanks Mike
Just remember where all the parts go when you disassemble the carbs. :) Check to be sure you don't have the old grey fuel lines . Change fuel filter. I like to use carb cleaner in the ultrasonic and not just warm water . That's about all I can think of
Thank you. Looks like all the fuel lines are crimped and not with regular hose clamps. It's a hard reach from the edge of the boat, working blind as it's hard to find the main fuel line to initially remove. Where is that hose? Fwd or aft end? I was wondering about the throttle cable separation. Didn't want to change, just to remove to release the cable from the controller wheel under the carbs. Also is an oil pump line connected to this assembly.... someone on another video mentioned it, but I don't think it relates to the assembly Thanks for taking time to respond to me., greatly appreciated Mike
Found the fuel line. Has a clamp👍and it's black👍👍. One last question before I begin. The cable that is on top across the 2 carburator air inlet (dish flaps)not sure at the moment the name that controls the rotation at the same time. Is there a trick to maintain the position of the secured clocking position of these disks. I'm wondering if I loosen the Allen nuts on the 2 places to disconnect the cables I won't know how to restore it to the correct position....or does accuracy matter?…......or Just need to retain sufficient tension on the cable? Thanks Mike
🤔Are torque wrenches not necessary in Sea Doo repairs? I missed where you checked piston height or checked the compression let alone the carburetor flow. I know everyone has their own way of doing things but Dude… this video jacked with my mechanical OCD on so many levels.
Hmm. Every bolt was torqued..Loctite on everything. Compression bench checked and is still 150 per side as of today. I did not check piston height nor did I check carb flow. I am not building racing engines . (squish check) Totally unnecessary for my needs. I use the standard #5 base gasket, standard pistons and never machine the heads. (I will buy a good used head vs having is shaved). Hopefully that puts your mind at ease.
I have the same boat. No acceleration at all and I have a beep code that points to the throttle body. If I replace the throttle body and sensors do I have to have a dealership reset the mpem settings? I don’t have the software.
Trying to find a cheap one to rebuild now. I’ve owned 3 snowmobiles, so these with the same motor should be close. Not sure if I want a twin engine or single?
great video, as usual! How would you get at the gauges in these boats? I've got a 95 speedster but 3 of the 4 gauges at the moment dont work. Planning on taking it out on the water this week! Thank you for all the good video you take!
On the 97 and up the gauges are accessible through the flip up hood . You remove the white bucket and they are right there and accessible. I am not sure about the 95's
I have a '97 Sea Doo speedster with the twin motors. [Missouri in US] One of the motors is frozen up or the starter is not working. I can't get the Sea Do dealer here in town to work on it because he says he can 't get parts. Looks like from your video you're not having any problem so apparently he just wants to sell them and not work on them. May have to do it myself. Never done this before so your videos are very helpful. Can you mention your source for parts and save me some time digging around on the Internet? Thx
If you are talking about the bottom end of the engine then yes. No gaskets just Loctite 5910 Parts are machined to go together perfectly. That's why you can't mix and match top and bottom cases.
@@abreubrian819 Hmm, I can only see a need for 1 battery unless the 2nd one is a back up. Normally they have one battery. The 2nd one may be set up so you can use the accessories and not drain the starting battery.
@@SeadooRefurb My engines starter just stops and locks up then the current burns the cables everytime i change the starter. what electronecllly do i need to replace?? please help
@@rkhokhlan remove the spark plugs. Then try to roll the engine over by grabbing the pto. If it is difficult to rotate then I am guessing you have a seized bearing in the jet drive. I don’t believe it is a wiring issue. It sounds like you are requiring a ton of power to roll the engine over. I have seen this issue before.
@@SeadooRefurb I have same boat, which requires Top rebuilt. If you are in Toronto Area, Would you be able to work on it? I can drop if off at your place? Please let me know. Thanks
@@BEDS4 Hi Bilal, I don't do any repairs or rebuilds on any one else's seadoo's. I just do it for fun and personal use. Try Jetx power sports. I assume that if the top end blew there is more to it. (possible head damage and carb issues ) Oil pump issues ? etc....

it’s a 2 stroke so you just keep filling the oil tank. on my 4 stroke I put a 1/4 line down the dip stick and suck the oil out with an oil pump.
