this weekend i just sheared the flywheel key on my 550 and it spun the flywheel nut right out the front of the flywheel cover and i found it in the bottom of the hull in front of the gas tank. i will post some pics in the carnage section as it is impressive to see haha. On that note i have found, spend as little as possible on these old skis and ride the shiat outta of it till it dies.
This is the problem with old skis. Their previous three owners had the same attitude.
