how much of it is still polaris? not to much.

Cases. Cylinders since approx 2006 are aftermarket............. Wait, isnt that what everybody else is doing on their yamaha's? XScream, DASA and ADA Cylinders..................... There is not much difference.

so i guess company PSI does the cylinders.... and x 2 on what BK said!

My 950cc, stock crank Polaris engine is almost done, and it's costing me about $3,500. I've seen smaller engines sell for way more. I have a brand new OEM crank, porting done for me and my riding, power valves, and it's all made in the USA!
My stock Octane engine has survived everything. I'm really impressed. I plan to stay Polaris, especially with this investment...

I will admit the 777 is just about the only watercraft/sled motor polaris has made that is of any quality.

the motors are good just all the parts that are bolted on them suck balz.

 

[speedysprocket]

The carbs suck. Pretty sure that's it. yamahas don't have programmable CDIs or a flywheel you time instead of having to move the stator...

 

[Polish jet pilot]

where did you source the cylinders? Looks awesome! Bet it will rip hard

 

[speedysprocket]

Crank Shop in Vermont. It's the same casting EME uses and other places. Just watch out, bolt pattern is slightly different from the sled cylinders to the EME ones that Power Factor makes the head for...!

Did I mention how fun it is trying to turn the polaris centripetal force pig. By far one of the least nimble motors I have ridden. IMO poorly designed flywheel.

This place made the old Malone cylinders before it was EME. Not listed on the site anymore though.

It is a massive flywheel, but so easy to time!

Biggest problem with the newer Polaris engines was the crappy PVL ignition systems, ditch the PVL crap, run total loss and most of the electrical problems dissappeared.

 

[just starting out]

I saw your ost on 1995 seadoo HX seat shock outer bellows and was wondering if they are available from you or WSM?
