Working on a 2001 947 DI motor. My question is regarding use of Loctite 243 and molykote on head bolts. Manual states “apply Loctite 243 (blue) below the screw heads. The diagram indicates apply molykote below screw head. Which one is correct? The larger bolt I show in the picture below is the original bolt I took off the original head and it clearly has Loctite 243 blue on its bolt head. IMG_4900.jpegIMG_4901.jpeg
 
Seadoo flip flopped quite a few times. The newest manual shows the same as your manual.
I would do it whatever way makes you more comfortable.
 
The 243 blue is only under the bolt head.
The threads need the Molykote "grease" since cooling water can easily get in that area and corrode and lock up the threads.
It's not a perfect solution, but at least there is a little bit of surface area under the bolt head for some 243.
