i am working on a friends XL 1200 waverunner. he had the motor rebuilt and the oil line came off the front cylinder after 20 minutes. melted the front piston. am installing a new crank and complete Cylinder kit. the problem i am having is a question about the crank installation. the two spacers between the rod bearings looks like they were coated with silicone when it was assembled. from what i have see on other posts that it looks like theirs has silicone also. I cant find this in the manual or maybe its just not in the PDF i am using. here is a picture of the silicone. do i put some there or just assemble with silicone just around the cases ? is this normal or did someone just put it where it should not be Thanks..
