Hello all. Haven't been on here for a couple of days because i've been tearing down my 9.9. First i want to thank all of you for your help. As a result of the info i got on this board i ordered a manual and disassembled my engine. I now have it in a million pieces but the good news is they all look pretty good. I do have a couple questions if anyone wants to tackle them. <br />1) I had a lot of water in the lower unit, fortunately nothing was damaged. The gears all looked great and the bearings were in tact. I am going to change the water pump although it appeared to be brand new. Where am i getting water from? I can't find anyplace except for maybe around the water pump. <br />2) As my partner stated in another post the tops of the pistons had some carbon deposits on them but overall were in good shape. They have some discoloration down the sides of the pistons but they are not damaged at all. I am replacing the rings but i was wondering about the carbon deposits. What causes and is it bad thing?<br />3) Any idea how i'm losing compression on my top cylinder (which is still about 120). <br />Thanks for everything. Please help where you can, much appreciatted.
