Greetings Group,

I have completed my deck install and new seating and carpet. I will be
posting links to the process in a bit.

I need to "service" my 3.0 i/o Merc and everything I can...Is there a step
by step guide or process anyone can share with me, along with what to get?
Or should I resort to the dealer that is not so local??

Thanks in advance!!!

A boating post finally. Thank you.

We're looking forward to seeing your work. As far as commissioning your
power train, I don't know if there are published step by step directions
for you to follow. There is no reason you can't do the get ready
yourself unless you come across a task you are not comfortable with
taking on. The only exotic tool you might need to do routine maintenance
is a engine alignment tool. Service the IO first. Replace the whole
water pump assembly while you are changing gear lube , check engine
allignment, check for worn or binding parts especially the gimbal
bearing. Check that fwd and reverse gear engage and the driveshaft when
rotated causes the propshaft to rotate. Remove the prop and grease the
shaft as well as the driveshaft and ujoints Look for leaks. If all looks
well install the IO using a new gasket set. A tune up and oil/filter
change is all the engine needs. Check the V belt and inspect all rubber
parts. tighten all hose clamps. When you start the engine you MUST have
sufficient water pressure and volume to the "ear muffs" connected to the
lower part of the IO. I strongly suggest you order A genuine OEM service
manual from Mercruiser.
