Polaris 750 Jet Ski Engine repair 

Great vid, good to see someone going through the same things I am while I rebuild my ski. $40 for 1 gasket... 1 gasket, one.

Awesome vid man I really need to do this to mine so I can save some money but I just don't have the confidence that I'll be able to find out how to put it back together

It depends on your bore. If it is stock you will get a standard piston. If you need it bored, you need to have an eversized piston and take it to a machine shop and have them match it.

Love your videos I have a 98 polaris slt 700 has no spark to the front cylinder 135 psi compression new coil same problems any ideas.

Do I need to pull my motor out to replace the piston? I just checked mine and I have a nice hole in the piston closes to the back, I know this is 12 years old! I appreciate your help

Too bad you didn't show how to install the rings. Also, where did you get the tools for the compression test. How is it done? It's ok hearing what you did but showing how you did it would be better.

I have been working on two stroke jet skis for almost 15 years you better do a fuel pressure check just a bad gas cap seal will blow the Piston out of your engine and on that particular ski you need to upgrade to a 3 line fuel pump and get rid of the two line pump or it will cause a lean condition Polaris is known for this also those reins should have cost you about $26 per piston and you want to Mike the Pistons and make sure that they are no more than one meal over I must be within a certain tolerance of each other or the motor will be out of time there is a lot to getting those to run right but if you know what you're doing they will run great that's called the Blue Fuji motor

Ive been following your videos the past week! Nice job

I have a 96 780 the center piston was bad and when we removed it we relied it had a decent size piece broke off. We had the jug honed and replaced the piston. My question is do I need to crack the casein order to remove the lost pieces? Where did the remnants go?

Thanks man, that post is a bit old. My ski is up and running...

@azdanielducati1 That's awesome. I am very glad I could inspire you.

And you need to spray copper seal on your head gaskets before you put it together because it will start to leak compression the spray can copper seal is great for those compress head gaskets and I don't care what they tell you at the place you purchase them you need to spray them

l need some tips on how to replace wireharness from cdi box to motor

@punchmaster123 Yep, it was the "IN" color then. These days is is navy blue.

Hello, I was wondering if you have one good jug and 3 pistons, if so how much would you sell them. Let me know thanks!!!

is the crank good in that 50 dollar engine

Good job man.

what did you do to clean the piston

I have the same one and have questions

@Aaronhernandez24 Not sure. Go to greenhulk and join the forums. Someone will be able to help.

Where the hell did you find those rings I bought a kit for my SLT like under a hundred bucks

I will get some video next weekend.

I’ve had no luck removing the jugs or the carb. All nuts are removed and they are still not budging. Does anyone have any ideas?

hello frisco do you know what size of piston i should use for a 750 motor ?

@mogyver69 Awesome.

You wouldn't happened to have extra pistons for one do you?

nice deal 50 bucks I'm going to bed on a 2002 Polaris tomorrow at a Goodwill auction. it needs a new engine but I wouldn't mind putting new engine in it anyways

@FriscoJarretts see it says tx you go to joe pole lake?

Yes, you paid way too much for those piston rings !!

I paid 360 for the ski and 125.00 for a trailer!

You can buy a new piston and rings for 40$ on line

I need a fuel pump for that same model I can't find it

I don't know much about Sea Doos.

I just got a free one today and dont even know where to begin..
