Taking my 200 h.p. 1989 yamaha to replace power trim motor, I have an engine hoist and I'm just wandering are there any pointers or steps in doing this, as far as taking the engine off safely. Also do I need to disconnect my cables, I have a foot or so of play and I need to just get to the bolts on the trim motor?If you have done this job before any wisdom would be appreciated.Thankyou Andy
