Hello. I am new to this forum. This is my first post. I recently bought a Sun Tracker 18' Pontoon with a 1993 40 HP Mercury Tracker Pro Series. I noticed some back and forth play of the motor while in the locked position. I pulled the lower unit to replace the Water Pump with a kit and while looking inside, I noticed 2 bolts far inside that seem to have lost rubber bushings or something and allowing the engine to pivot back and forth. I am sure the repair is easy, but would require me to remove the Drive Shaft Housing in order to access those bolts. What is the simplest way to remove the drive shaft housing? Or is it easier to bring the Motor to a shop and let them do it? Any idea of the cost?

What is the s/n of your engine and I will see if I have the service manual for you.

Your s/n comes up as:

MERCURY - ( 40 H.P. (1994 ))
Serial No: 0G047741 Model No: 1040312PT

Parts List for model 1040312PT:

40 HP30 JET - Mercury, Mercruiser, Force, etc. Parts Lookup

The upper and lower mounts are seen as items 8 and 29 under DRIVE SHAFT HOUSING ASSEMBLY, if that is what you were looking at.

Service manual is P/N: 90-814676R1 and if you PM me with an email address, I will send you a copy.

The work to replace those mounts is basically a nut and bolt job if you have any mechanical experience but the powerhead will have to be removed to get the steering arm and the bottom yoke off. They are seen as items 7 and 9 under SWIVEL BRACKET.

Thanks Gerry,
yes, it looks like item number 8 is what I am looking at. Or at least what is left of it. I PM'd you my email address. Hopefully my mechanics skills are sufficient for this job.

Manual is on the way Sven. There are many knowledgeable people on here who will be more than willing to give you a hand if you run into problems.
