Check the fluid level in the trim pump. You can find the trim unit by listening to the trim motor.

There's 4 different trim pump they used. The reservoir has a fill plug. Remove the fiil plug and with a piece of wire check the fluid level. The fluid should be 1/2 from the top of the fill plug. If you have the plastic reservoir you can see the fluid level it should be about half full. # ***** is the fill cap. http://www.boats.net/parts/search/Merc2/Mercruiser/R-MR%20Alpha%20One%20%28Drive%29/6225577%20THRU%200D469858%20%281983-1990%29/HYDRAULIC%20PUMP%20%20OILDYNE%20PUMP-%20PLASTIC%20RESERVOIR/parts.html Lets get the drive down first it may shift ok when down.
