Your pulling against the flywheel, I had the same problem...
I have the same puller and ran into the same problem... here is the soulution...

The presure end (center bolt) of the puller does not fit in too the cavity where the bolt came from... the flat end and pointed end they supplie dont work.... hence your pulling against the flywheel...

At the time what I did was back out the flywheel bolt an eight inch and then pulled against it.... Once the flywheel popped I removed the bolt and then the flywhel...

Although once I did that it was recomended to me not to beacuse it puts alot of pressure on the threads.....
The second time I got some metal stock (larger than thread hole but smaller thatn flywheel hole) that would fit in there, works great then....
Hope this helps you!!!

An 11mm 1/4" drive socket works perfect here.

Still no luck on removal of flywheel on the blaster. The SJ was no where near as difficult.

Again, the engine is in the ski should I remove it? This is beginning to tick me off.
 
First thing is to get the garage cooler full of ice and beer, (Tequila is good too, gives you strength) If you are womping on that bad boy with a puller and a rope and nothing happens, (SLOW DOWN!), drink with your buds and pray to the Jet Ski Gods for forgiveness..
All kidding aside, the rope and steering wheel puller will work, sometimes though what has happened is that the flywheel has "rocked" on the crankshaft and actually "welded" itself to the tapper of the shaft.
This sounds crazy but I am old and my body gets po'ed at me all the time,,like the previous post's have mentioned, "air impact wrench", if you have to, go to a local auto shop, slip the guy a 20 and a bottle of Jack.....It's worth it....

Flywheel lock

I offer a flywheel lock that will hold the flywheel in place while torquing and/or removing the flywheel. If the flywheel is difficult to remove, I suggest driving your ski to a local tire shop, repair center, etc and offering them a few dollars to remove the flywheel with a strong impact.. Removing the flywheels with hand tools can be difficult, and the "rope trick" puts an added load on the rod bearings, pistons skirts, etc. The 20 bucks and a "bottle of Jack" is well worth it, as you can easily cause more damage than you are repairing. You might also look at the "electric impact" on my site that we use at the races, etc. Thanks,

I use an impact wrench on the flywheel puller bolt as well. Yanks it right off there. If you don't have air tools you can get an electric impact wrench at harbor freight for $50. I have one in addition to my air tools, and it works just as good.

Update:

On Feb. 8th I was able to pull the flywheel on the blaster. I exchanged my Craftsman harmonic balance puller for a new one (the threads and head of the bolts on the old were stripped).

I removed the engine from the boat and placed it on the floor in the garage (on a runner of carpet from the house). I marked the threads of the bolts with a sharpie marker using my 62t flywheel from the superjet to ensure I did not damage the stator on the blaster engine. If you thread the bolts too far on the puller you can damage the stator.

Anyway, I also marked the bolt head with a dot to count the turns so all three were threaded equally.

I used the largest socket possible that would fit inside the middle of the flywheel so the puller was countered on the crank. If you do not use a bolt, socket, etc. the puller will press against the flywheel and you will achieve nothing.

I used an 8" piece of 3/8" rope in the front cylinder and used a breaker bar and a pipe to get the additional leverage required to pull the flywheel. It would have helped if someone could have held the engine place, but I managed.

The extra leverage helped and I was able to finally get the flywheel off. Appearantly the mechanic who last replaced the top end red-loctited EVERYTHING. Even the flywheel and woodruff key.
