Have a buddy with a 21 ss extreme 225 Evinrude. It has a slidemaster manual jack plate and we are trying to raise the motor but the center adjustment bolt is froze in the plate. We have tried spraying blaster to loosen up but have had no luck. We have also double nutted the bottom of the adjustment rod and pulled on it pretty good but are worried we will brake the adjustment bolt.

an yone got any ideas??

Thanks
