Howdy - tried to put my lower unit on my engine yesterday (1966 merc 95 hp o/b). Got it lined up with the gears, no problem but didn't have the right nylock nuts and need a bolt as well. <br /><br />I have a couple questions:<br /> 1) Since my lower unit casting is made of aluminum (i think).. should I use "stainless steel" nylock nuts to bolt this thing on? I've heard that aluminum and steel don't act well together (in a chemical reaction sense). But I would assume that stainless would be the way to go...<br /> 2) Do I need a gasket or some type of seal inbetween the lower unit and the power head?<br /> 3) I don't have a trim tab on my lower unit...do I need one? From what I understand it helps with steering, but am not sure if this is critical? I would think that I'd need one. My parents gave me this boat (with a damaged lower unit - unattached) and never gave me the trim tab. I've since had a different one rebuilt...so the shop I gave it to, to fix it, did not put one on...should they have? I'm beginning to question this shop more and more each day. If I do need this....what type do i need? Any advice here would be great.<br /><br />thanks in advance<br /><br />-kary
