There are 4 bolts holding the 2 pieces together, 2 in the back inside the cowling, one in the front inside and one in the front outside, right near the pivot point. I had to remove the airbox to get the front inside one out, the rest were no prob. The it is a rasslin (wrestling for you yanks) match to pull the covers off of the rubber mounts, for each side pull straight towards the sides of the boat

Randleman, It looks to me like a hack may have gotten ahold of your motor in its previous life. Your t-stats have been hollowed out and your poppet valve has been removed. I think they were chasing cooling issues before you got ahold of it.

Ok, what does the poppet valve do. I know it has to do with cooling, but does it regulate the amount of water through the heads ????

Mine doesnt do anything.

Its supposed to open up to allow more waterflow through the motor above 2500 rpm.
