Hence the reason I talked him out of buying my $200 top end. Yeah it's a 701, but when you can get a complete engine with electronics for ~$150 more then it's a no brainer for a backup ski.
Edit:and it's damn hard work to blow up a 650. You have to purposely sabotage it. Those motors don't really make enough power to grenade on their own.

Cool just let me know. And it's the piece between The starter and flywheel. The starter hits the bendix and that turns out and hits the flywheel. At least I'm Pretty sure that's how it works lol

Guess I'll be the only one to go against what others say.
Get a used 701. 650s suck. A 701 can be found for 2-450 bucks on eBay. I've bought more than I remember. Use everything else from the 650, and watch the power double. The only thing of any use on a 650 is the crank and carbs. The rest is aluminum paperweights. Why invest in junk at all?
I live a little south of you, I'm up there all the time though. I could show you how to tear an engine down and rebuild it in prob 2 hrs. It's really easy. These engines have like 30 bolts total.
If its a huge deal to get on the water I got a 650 bored to 7 something with wisecos in it that came with a sj I bought, it hits ok but still nothing like a 701. I'd let you use it till ya got something else.

Sparkplug thats a really nice offer. Op take him up on that stat!
I have to disagree with the usefulness of the 650 just because I play on the low end of the financial totem pole of thrashin out jet skis.
@BruceSki mentioned that you have to literally TRY to break a 650 and after almost 3 seasons of strait up abusing mine with water ingestion and hard riding I think THATS the main selling point on why to run one for the budget minded rider, especially for a 2nd boat. I see 701 based stuff needing engine work all the time. On a 650 its almost always electrical or carb related which is comparatively cheap to trouble shoot.
Pluuuusss if you wanna get fancy panced, you can throw like ANY aftermarket prop on a stock square and the difference is great. It starts to feel like a stock 701. Not saying more power...but 650's low end hooks you up RIGHT off idle.
Anyways, this is all just if you're broke. lol
I don't even know how my boat is pitched but you can throttle chop and ride at 20 mph slashin around. The power band is all low/mid and there is NOOOO top end at all. lol.

I have a plan to put together a clapped out old square hull I'm retiring from primary status to secondary status. Going to run a cement mixer 650 motor with an msd, a prop and maybe a bootleg pipe. Guarantee I can flip and roll it in surf no problem.
Basically doing it just to say I can. Haha

Haha. your reason why is the best part man. I need to get out to the east coast this year for a freeride for some real waves and some salt in my lunges.

Whoa whoa, everyone cool it a bit.
Dont take it as an insult Sparkplug.
Yes, I do want to spend money because I don't like possessing others things that I don't own.
Everything I possess I own outright with no debts or loans, hope you can understand that.
Also, I know how to build motors. I simply don't want to invest the time in doing so right now, I have other priorities.
CRJ hit me up with pics and shipped prices for top end only and the whole shortblock.
I assume its on stock bore?

I didn't take it as an insult. Iwouldnt use someone else's motor myself, but I would let someone use one of mine. If that makes any sense. I let buddies ride my bikes and skis all the time. Toys are more fun with other people I think.
If you didn't wanna use the motor that's up to you, it's just sitting on my shelf tho, for like the past 3 years. And I tried to blow it up before I swapped it out for a 701, and couldn't.
My buddy has a complete 650 top end he'd prob sell for like 60 bucks good to go, but he's in new York for the next week.
Did you buy the skis in redding? Or up here? Any pics?

Cool, I'm the same way and I do appreciate the offer. It's just if the engine blew or something it would be me in an uncomfortable position that I would rather avoid. 
I always let others enjoy my toys as long as they can respect them.
I'd be super interested in your buddies top end, especially since I could just drive down rather than ship.
I got the skis in Oregon.
I've tried attaching a pic from my phone, if it doesn't work I'll throw when up when I'm home.
