    2004 Polaris Freedom Rebuild

    Hey, im new to this forum but not new to polaris machines. Ive built several polaris snowmobiles (im from minnesota) and 3 polaris jet skis. I picked up a 2004 polaris freedom 700 with a blown engine for a steal. Im very familiar with engine building but have a few questions that maybe the more skilled members may have answers to. The rear cylinder is locked to the crank, pistons are in decent shape and the jugs are still great. I was curious if it would be best to just replace the pistons and crank or tear it all out, and replace with a new engine. Currently has the 700 in it but i was wondering will the 777 work with the current carb and pipe? On SBT they sell a installation gasket kit that works for 700/777/800. Anyways if anyone has a clue on 700 to 777 engine swap or perhaps where to buy a new engine. Also if i just replace the 700 with another what mods can be done to get a little more power?

    Thankyou!

    without a 777 core you can rule sbt out.cdi is different as the stoke is 68mm vs 70mm on the 777.go with a 700 replacement.not much you can do to really add a lot to it.92 oct domes,and a recurved cdi to match.6 vane pump stator,different reed petals,replace the stock single carb with a set uf dual carbs,but even then you're not gonna see a lot of difference except for the bottom end acceleration.is this the blue setup??

    Thankyou for the quick response! Yeah i knew id have to knock Sbt out with an upgrade but i was curious if all the 700 parts would allow for me to upgrade. Blue setup as in the fuji engine? It has the red twin in it, the body is yellow. Also bought it an it has barnacles dried onto the jet/impeller and body any clue on how to get those off nicely? Once again I appriciate the quick response.

    Also would the older 700 engines work in this new model? What exactly is the difference?

    Week 1: Ordering products

    So finally figured out everything that needs to be done to this machine.

    I ordered new marine vinyl yellow and silver from fabric.com. Great site! Got everything for about 20 dollars.

    I thought the impeller was blocked due to the sheer build up of barnacles but turns out the steel wear ring was bent inwards, So now i need a new jet pump. I do not have an impeller removal tool so i cut the extender ring free from the impeller- it was trashed anyways.

    The left tire went flat on the trailer; a bottle of slime otta do it ha

    Also in progress to either order a chinese knockoff engine (700) or the core of a Polaris. I am unsure on what to do because I ordered a gas scooter and 4 wheeler both china products. I beat both machines and they still run to this day, obviously built with less quality but they still work.

    The bottom of the hull is covered with a salty waterline and barnacles, cant wait for that... Im thinking brillo pads and a cleaner?? Sand it off? I have no clue, any idea's would be greatly appriciated.

    The jet ski came with two batteries, one is 8 years old and the other 4 years. I sucessfully desulfated the 4 year old one with a smart charger, charging and discharging the battery several times.

    So i completed the project about a month ago. I used a 97 polaris engine with the stator and pipe from the 2004 engine. It is turning about 6700 rpms on the ocean 1 or 2 people.

    The seat was reupholstered and looks amazing after belt sanding down the rear yellow part. I was able to drop the engine in with the exhaust bracket and intake bolted on, no carbs.

    I mixed the tank 100:1 and have the oil pump turned up a tad, needless to say you can smell the oil ha. Was just being safe as I was unsure if the oil pump was 100%.

    Looks like you have room there for an analog speedo on the other side of the fuel gauge. You could get a kit for the early 650s and 750s. Would be a cool looking add on.

    I scrubbed it off with clr but they are still there in areas. Actually riding it and beaching the ski has taken some of it off. So if you want your hull to be perfect then sand paint and polish.
