Hi Wade,<br /><br />If it's like my 85 120 hp:<br /><br />Find a socket, swivel and magnetic insert for removing and installing the shift rod screw.<br /><br />Use a coathanger to align the screw and the holes when putting it back together.<br /><br />Make sure no one touches or turns the shift rod when the lower units off, these screw in and adjustment/specs are critical.<br /><br />Clean the mating surfaces between the lower unit and upper. I have water leaking out of there now. Maybe I should have "flat filed" surfaces looking for high spots.<br /><br />Hope this helps, and Good Luck!

I replaced mine for the first time earlier this year. Hardest part was getting at the shift rod to disconnect/reconnect it. I found it easiest to remove the lower cowling. This provided plenty of room to get in there without relying on magnetic screwdrivers or knuckled sockets.<br /><br />Have someone handy to help you remove/reinsert the lower unit. It's a little tough to hold it in place while inserting the bolts all on your own.<br /><br />Oh yeah, when inserting the new impeller into the housing, use a little dish soap as a lubricant. Helps get the impeller in there and just washes out with your first use.<br /><br />Good luck.<br /><br />Brew

Re: Water pump removal

To make the shift rod screw easier to remove, I drilled a small hole in the cowling inline with the screw.<br />Then used a 1/4" drive socket to remove and replace.<br /><br />pbailey

Re: Water pump removal

well lets say the shift rod is moved by mistake, can a lay person do this at home or do they have to take it in and pay the 75+ shop time to move a half a turn or what ever back.<br />omc made a special tool for this, but what can a back yard mech do????<br />-<br />not trying to take over subject. figure it would just help to know.

Re: Water pump removal

wade, make sure to put the grease in the kit on the splines of the driveshaft only (not the top). Also, use a little hardening Permatex on the pump base where it contacts the wear plate to ensure a good seal. Do not allow any sealer to get inside the pump housing. Use non-hardening Permatex on the cap screws holding the pump together and all the external fasteners holding the lower unit to the mid-section (if you ever want to get it apart again)!<br /><br />Good luck.

2K,<br /><br />Shift rod can be set to height using a tape measure. It's just a matter of knowing the height spec. from lower casing to hole in rod, +/- 1/32". But knowing where to measure from, and if it's in neutral ect. can throw off a first timer. If it backs off 1/2 turn on removal, gotta know it backed off and didn't advance cause I learned the hard way. I scribed a line on it even at the pump, but then it got pulled out so I thought it was unscrewed....... started turning it in to the scribe line, and became lost...... But thanks to the guys here on iboats.....
