Re: water pump
Lastly, none of the videos address reinstalling the stern, any tricks to making it easier, or things to look out for?
yep, it's heavy and a two person job at best. i agree w/ Rick, take the whole thing off. there's pm to do by pulling the drive. + taking the lower off and more importantly, putting it on is much much easier on the bench. like a 1 man show.
if ya do remove the lower only. continue to have it in fwd. if not just for the reference so ya can put it back together again. i always get grief with the water tube and guide lining up. best i can say is do it like the s/m says. tube in the water pocket cover, guide in the water pump housing w/grease on the ends. load the prop with a bungee in fwd once in fwd to keep it there. if the prop turn cw at all it won't be in fwd any more and may cause ya to assemble the shift shafts incorrectly.
-don't forget the quad ring.
-don't forget the washer on top of the lower shift shaft.
-ya can eliminate the oring if ya got it at the top of the drive shaft in the lower.
-feel the first drops of gear lub for metal shavings when draining it. there should be none.
-i like to pressure test the drive while it's off (when still a complete drive, not seperate upper and lower). see if there's anything that could be getting ready to cause me grief.
-check for seal wear just under the splines on the drive shaft in the lower.
-use correct tightening specs. for the water pump housing. the bolts are not real tight and measured in in. lbs.. there are 3 different torque values for the 4 bolts that hold it on too.
it's not a horrible job, but not the easiest either. take your time and read the s/m on the proper procedure. if ya don't got a s/m. get one. a mercruiser one. s/m #2 (C-90-71707)is what ya want.
if ya got questions while your doing the deed. feel free to come here and ask away. lots of good folks here that are more than willing to help...
