I have started to search for repair manuals for old mercurys,so far with no luck. Seloc starts @ 1965,which may not relate to a 56/57 wizard.I am a recent member of the national organization the fla chapter and jason's so if you are aware of a member willing to copy and sell or just sell what they have, i would apprerciate it very much.
East Coast Marine sells this one. Supposedly a great manual, but it is a pricey one new. People have picked them up off of ebay for cheap from time to time.
Pre 1965 Service Manual C-90-25500 (Mercury) is a pretty significant investment. I purchased one new
when they were about half of todays price and had
to think long and hard. Used and grimey manuals
just as useful. If you are going to work on a
model for which East Coast can provide a Parts Manual,
I would suggest buying the parts manual...it will save
you time and money.
I am aware that others may disagree..."We don't need
no stinking manuals" seems to be the feeling
among those with years of experience...and they are
right (mostly)...the manuals were intended to guide
trained dealer mechanics with factory service tools
to work on recent model motors...from there we have
to wing it.
Thanks for your help, i'm collecting all the information i can before i start a recon project.
If you know what years and modles used left handed threads,and where on the engine they where used,it would be nice to know. Is there any on a56 pwrmatic 12? Also is there any special tools required to remove lower unit and w/p assemblies, and flywheel? your help in in this is much appreciated, Thankyou. Dan
Several good questions...to best of my (limited)
knowledge the screw in water pump covers are opposite direction of prop rotation so any tendency of prop
shaft rotation would be to tighten cover. Not too
many models later the water pump was moved to a
location above gear case on drive shaft. This was done
to make room for gear shift mechanism and perhaps to
simplify sealing water out of gear case.
Buying the Parts Manual for the Make Model and Serial Number of the motor you intend to work on is a wise use of your money. Within last month or so I have seen Pre 1965 Service Manual on Detroit Metro
Craigs List for $45...no bargain but would save
enough to purchase a new impeller and seals for
water pump and drive shaft on many Mercurys of this
Tools...manual strongly suggests use of Mercury Service Tools for many repairs. Dealer mechanics
way back then could probably justify investing in
them because IF he had the work on hand these tools
could help him get more done correctly the first
time with less chance of a come back which put more
money in the pay envelope.
For most work you can either make a one time tool
or work around the need for a special tool.
The Inner Sanctum of AOMCI has a Mercury Service Tool
Catalog from early 1950's (there are later tools
covering later models in other catalogs) If you
read the catalog and look at the tool illustrations
you will get a pretty fair idea of what the tools
look like and how they are used...it does not take
a great machinist to make a version of a tool that
will do the job.
LASTLY...the biggest problem I have found in working
on early K Models is crud and corrosion...even my
few original tools are no match for really stubborn
fasteners and screw on covers...solvent, heat, patience & gentle force usually work eventually...
sometimes something gets broken which begins a parts
search...nobody bats 1.000
I have a fair knowledge of early K Models (not perfect) If anyone has a question on them I can
probably help...KE7 and later Models of Mercury
or Wizard are not my cup of tea.
