Sliding Clutch Dog

[PinchiPancho]

HELP! I have an 89 Mercury 100HP Outboard. A month ago my lower unit cracked when my friend lowered unit(LU) too far when we were washing down... I have since then gotten the LU welded and I have spent the past two days trying to get it back on my boat. I manage to get it on but REVERSE will not engage. Does any one which way the sliding clutch dog should face when installed? I think I might have put it on backwards. The dog has two sides, one has square teeth which look like the top of a rook (castle) chess peice and the other has teeth with a slanted side. I wanted to know which side goes to the reverse gears that are on the propeller shaft. Right now I have the slanted side facing the gears that are located on the front part of the LU. Any help would be greatly appreciated.

Re: Sliding Clutch Dog

Thanks Laddiesservice,<br />That answers one of my questions and removes doubt about whether or not I assembled the gears correctly... My next questions is... <br />Do I have to drop the lower unit again in order to align the gears? or can they be alligned without droping it? I noticed that the shift rod had three positions or notches on a somewhat round metal peice that turns when the gears are engaged.... my questions is... is forward at the bottom of the three notches or the top?

try to have someone turn flywheel back/forth while<br />applying upward pressure to align shift splines.<br />both L/U and shifter should be in fwd.<br />good luck,<br />M.Y.

Re: Sliding Clutch Dog

Thanks mellow yellow... maybe you can answer my next questions which I have also posted.... where is the forward position on the shift cam? is it at the bottom position of the cam or the top? Should the cam have a groove in the middle where it makes contact with pin that moves the sliding clutch dog? or is the groove a sign of excessive wear and the cam should be replaced? I have never seen a new cam so I am not sure if they have a groove or not.

The top of your shift cam is reverse and everyone I have seen has had a groove running along it.<br /><br />Best of luck Keith B..
