Lubrication questions on a Mercruiser 3.0 LX

[rodrigwa2005]

Here I go - I decided to get away from paying someone else to do this for me - downside is I am rookie so I am looking for some help from more seasoned boaters.<br /><br />I got a Alpha One 3.0 LX, I/O, Mercruiser transom, '97 with power steering.<br /><br />Specific questions I have are:<br /><br />- On lubrication for the power steering unit - I keep looking for the lube fittings ( manual indicates the use of Quicksilver 2-4-C marine lubricant) - can't locate them - All I found were orifices ( flushed with the body of the unit) plugged with what looks like tiny bearing balls - nothing close to look like a lube fitting - Any suggestions?<br /><br />On the engine coupler - Manual indicates "lubricate every 100 hours or every season with Quicksilver engine coupler spline grease" - help required is: How do I access the lubrication points?<br /><br />Thanks in advance.

Since it sounds like you have the Merc service manual, look at page 1B-14 for lubing the coupler. There should be a zirk on the coupler, If you don't have the grease zirk, you have to pull the drive and lube the shaft.<br />Not sure what to tell you on the steering cylinder. The cables seldom have grease zirks.<br />The steering cylinder itself will only have a zirk if it's the old style cylinder. The newer doen's have one.

Don:<br /><br />Not a Merc manual, I am going with a Seloc repair manual which covers, to some extent as you can see - the engine I got.<br /><br />Could you point me where to look for the zirk ( in case this one has it)?<br /><br />Waldo

Sure, page 1B-14<br />Here is the online manual.<br /> http://www.boatfix.com/merc/Servmanl/13/13covr2.pdf <br />Click where it says GM 4 Cylinders, then click on the B under section 1.

Forgot earlier, here is a manual for your drive.<br />You will need it when you do the other maintenance items the Seloc doesn't tell you about.<br /><br /> http://www.boatfix.com/merc/Servmanl/14/14cover.pdf

funny those drive coupling splines.. they go from a system that relies entirely on a thin spear of grease being put on the drive splines when the drive is fitted most of which would get wiped off.. to a totally sealed tube system that once packed full grease via the grease nipple looks like it could be left alone for the life of the life of the unit..<br /><br />just thinking aloud.. he he..<br /><br />trog
