As someone who has broken this motor apart more times than I choose to count due to timing, THE TINY HOLE IS THE KEY TO SUCCESS! I thought I would be able to tell with the head off where the piston should be to time... WRONG. You need to see that line in that small hole and then lock the crankshaft as suggested with a longer bolt. The retailers have some special tool to lock it that is not sold to the public, so use a bolt. The only thing I can as a suggest is rather than turning the engine with the special tool down where you put the impeller shaft, you can use a T50 star bit to turn the motor over from the valve train, BUT BE SURE TO REMOVE ALL VALVE BUCKETS!! Failure to do so will still open and close valves, which may bend valves when you turn the motor over with the cams (took me 2 sets of valves to figure that out.) with the buckets out, the valve train can’t make contact with valves Great video!
Thanks for posting the video - i struggled and struggled to find that line as well. (mirror, flashlight ,... so on) I have another crank sitting here and its is notched out as a ">" on the crank. Still having issues with the Spark and seems like timing or a sensor (sensors and wiring tested fine) - but believe that's what i was looking for. Hope that is correct ..
There's an special tool for that but you can use the same shaft with a pipe wrench, also the piston #3 is coming up when you see Mark on the crankshaft
you can use the same shaft ( some tape around) with a pipe wrench or search on Google or eBay this one Sea-Doo Impeller Removal Tool Spark Seadoo Pump 529036273
i don't have a motor available right now to confirm that but 100% look at the video again, just do it by marks, remaining i think the 2nd piston was close to top end center but not totally up
No matter what I do, I cannot find that mark. The piston closest to the rear of the jetski is all the way down and I see metal but no distinctive line. I have moved the driveshaft back and forth to see where it is but still nothing. Any suggestions? 2016 Seadoo Spark
@@leomarrero I think I found it but im not 100% sure. Piston 2 is at TDC and pistom 3 is on its way up. I see a small indent. Lets hope thats it or else ill be buying a new valves kit
@@leomarrero Just got it aligned. My next challenge is to put the timing chain on over the cams. How you do do this? It doesnt seem like the chain reaches?
@@thegarre 1 tooth no, but several yes, you might have bent valves, set the time again buy a compression tester on autozone, napa.... and read the compression, if compression is 0 make your plan to rebuild the valves

Great video!
I explained everything in the video, k have done this on several sparks with 100% success, thanks for your comments 👍
Thank you so much!!!

did you get to fix it?
Thanks for the video!
I did everything on your video but not getting any compression at the spark plugs
did you check the valves before install the head?
☺️🙏 thank you so much 🥰
Any questions let me know
Great video, thanks for sharing!
Whats the tool to you used to crank the engine to get the piston to top dead center?
There's an special tool for that but you can use the same shaft with a pipe wrench, also the piston #3 is coming up when you see Mark on the crankshaft
@@leomarrero What do you use to remove the clamp on the 2nd boot? is it necessary to disconnect the crankshaft? Thank you for your help!
@@michaelkelley4421 if boot isn't leaking isn't necessary to remove from shaft
@@leomarrero thanks, i realized after I already removed it that i didn’t need to. I got it timed and ready for the water. Thanks again!

If you set timing mark of the crankshaft to the small hole, the second or the center piston should be fully on top? I am right?
i don't have a motor available right now to confirm that but 100% look at the video again, just do it by marks, remaining i think the 2nd piston was close to top end center but not totally up

it is there, when the #3 is coming up, you will see it, be patient, use a flash light

@@garrettomalley6436 is the only mark on the crankshaft, it's visible through the crankcase hole
@@garrettomalley6436 #3 is coming up ( #3 cylinder is the one closer to the shaft)
@@leomarrero Just got it aligned. My next challenge is to put the timing chain on over the cams. How you do do this? It doesnt seem like the chain reaches?
Are you sure the front piston has to be all the way up? My timing marks lined up when the center piston was all the way to? Kinda confused here
piston #3 is the one closest to the shaft , once #3 is starting to come up you will see a line mark on the crankshaft
i am 1000% sure
@@leomarrero mine must be different lol, because my middle piston has to be TDC for it to have the groove in the flywheel. 2015 engine
@@monkeynuthair1638 they have the same motor
@@monkeynuthair1638 did you remove the bolt from crankcase like in the video?
if the timing chain skips a tooth should you replace any parts?
in normal conditions they shouldn't jump any teeth, just put the time again and check the tensioner
@@leomarrero so they are not interference engines? the pistons won't hit the valves?
