thanks wilson.. for a minute there i thought i was alone.. my problem is i cant remove the screw . when it broke half stayed in and the other half is just hanging. The front part of screw the one with the slot in it cant be removed. There is a big plastic washer on the screw the exact size of opening in the tilt/trim bracket. this prevents me from even getting to the broke part in the pump. i need to remove the front part of screw before i can get to broke part in the pump. any suggestions..

you have two choices. you can try to cut it behind the washer or do what i had to do and remove the whole trim tilt system. i had to so i can get the trim motor rebuilt and i broke my screw off as well and cant find a new one. here

You definately don't want to open the bleed valve with the motor trimmed up. That would pull air into the cylinders. You want to lower the motor all the way down and then bleed the air out. Also make sure that there is enough oil in the unit. Trim motor all the way down when putting oil in. Otherwise you'll overfill and blow cylinder packings.

The small seal on the pilot valve is probley bad, unless something broke inside. Impact valve is spring loaded and should return to correct position after impact. You should be able to remove the valve and replace the seal. The seal number is same as 125 Force, search Force tilt and trim for number. [links]

Thanks for the response. I've learned a couple things over the last few days. I guess I'd better share since it seems we have no resident experts in this matter. Buying the manual helps.<br /><br />1) There is no bleed valve. This unit is "self bleeding". You trim it all the way up and down 3-5 times and it should bleed itself.<br /><br />This did not work in my case <br /><br />2) Since I can lift the motor when it is trimmed down, (no reverse lock) I'm going to try the manual release valve and O-rings next. Plastic screw with 3 small O-rings and a retaining clip for $34.70. They should be shot for that! <br /><br />3) Next I will look at the trim piston rod assembly. This has the impact relief mechanics inside. Since this happened after I hit bottom I figured this would be next best candidate. Of course I need to buy a face spanner wrench to do this. Also, Mercury recommends that you replace all O-rings when you do this and the O-ring kit is $51. for rubber O-rings! <br /><br />4) After that if this was a 2000 I would need to replace the pilot valve assembly, but because this is a 1999 (same for 1998) model I will need to replace the entire pump assembly priced from Mercury at $428. <br /><br />5) After that the whole trim cylinder assembly gets replaced and then the entire trim/tilt unit goes bye bye. Found rebuilt units for $585.<br /><br />Hope I don't have to go that far, but a mans gotta do what a mans gotta do. more
