I could really use some help here. I have a 1995 searay -searayder 120. I have pulled the nuts that hold it to the hull and jet pump, the fuel lines, exhaust baffle and throttle linkage. When I lift on the engine the whole back of the boat lifts off and the engine will not separate from the jet pump. I tried heat, air chisel, pb blaster jumping on the swim platform, brass hammer and it won?t budge. Am I missing something like a bolt from the underside or putting it out of gear?
