How hard is it to replace a 96 XP engine?

My buddy may give me his 96 XP that has a seized engine. I have a decent tool set and am fairly handy. How hard would it be for a couple of people to replace an engine in this ski? Is SBT the best place to buy an engine?
 
It's easy. Engine isn't very heavy and two guys could easily lift it out.

Be sure to note where there are any shims, and be sure they stay in the same places.

I have done it both by leaving the mounts on the motor, and leaving them in the boat. I found it easier with leaving the mounts in the hull.

Your back will be sore from bending over and working in that confined space for a couple hours.
 
If only seized, why not just build the top end?

Get off way cheaper! Still easy job.
 
It's not a good idea to just do the top end. It's better off to do the complete engine.
When you install the rebuilt engine, make sure you re-align it with an alignment tool.

Okay, so you think this is a bad idea. Looking over the seadoo manual, it talks about just doing top ends. That is where I came up with the idea.

Looking back over the post, I see that not knowing what is the exact cause of the seize, that investigating the whole engine would be the proper way to go.

I know that I am fairly "new" when it comes to "rebuilding" or even attempting to work on an engine. But instead of red lighting me, why not explain why you feel that way, (should rebuild bottom end too), so that I can understand what is the reason, and what one should look for.


I know in my case, knowing what the whole engine is doing, has put my mind at ease. I guess that is what you are trying to say. I appreciate all your help with the forum, and myself in particular.

So just a newbie giving out bad advise, will leave my thoughts on stuff to myself, and continue to learn right from wrong.

Sorry guys,

JD

I apologize.
I'm all about saving money and in many cases, if you just do the top end, there are issues that have to be addressed in the bottom end like bearing and seal condition.
Last year I worked on a customers 95 GTX. A piston seized and he just wanted the top end done. I tried, with no success, to convince him to do the bottom end also. Shortly after, the crank failed. Here are the pictures.
I'm sorry for being so blunt without an explanation.

No worries, I should understand given what I am going through with my ski.

If it seizes, do it all. If it turns, (runs), and low compression, then perhaps a top end. (more reading).

I just didn't get why I was fragged to -33 for making a stupid comment.

Looking at I would guess 80% or so of the posts, they are from guys like me, wanting to learn.

Likewise, going through it all, I'm not going to make the right call, tons of times. Someday though, I hope to get it right.

Again, making a mess of it all was not my intention.

personally, the peace of mind and warranty would lead me to buying a rebuilt from a reputable dealer.

No worrying about if you built it right, all parts were useable and assembled correctly,etc.

I have done car engines and I always worry that maybe I didn't do something right and it is waiting for me to be 300 miles from home and something will let go, and I will have engine block all over the street.

Buying one that was built by experts would be quicker, easier, and most likely cheaper in the long run, especially if it fails and you have a warranty to fall back on.

That is just my opinion.

It is also my opinion that I could fix Chester's crank with a couple tubes of JB Weld...:reddevil:
 
Yeah, that feeling in the back of your mind...... did I forget something?

For me the ski has been total therapy. Kick the day off and settle into a challenge. My mind stops running on work and I am forced to slow down and think, because I don't know exactly what is going on.

Been great, I am almost certain that I will do it again when this ski is done. Already eying couple of skis.

Looks bad chester but what did that have to do with only rebuilding the top end? That looks like a crankshaft that could have been rebuilt and not noticed the fitigue that was caused over time and rebuilt only to fail later. did you notice a bad bearing or any thing? Thanks. Robin :cheers:
 
The plastic cages, that separate the balls, in the 2 front bearings had failed. This allowed all of the balls to to rotate to one side and let the front of the crankshaft wobble severely until it broke.

FREE SKI.......Are you already ahead? What is the condition of the rest of the
ski? Post some history if you want us to help. If everything else is wore out, you
would be better off buying something thats been maintained.
