Merc Motor.

Post by cusoak » Mon Aug 26, 2013 4:21 am

Well I picked up my 61 Merc 45 hp from a Merc out board racing mechanic.
He ck compression ok
He pulled mag off and went through and cleaned up everything, points rotor and contacts in dist cap. Installed new timing belt.
Pulled carbs off and cleaned, rebuilt.
Put lower unit and rebuilt water pump.
Replaced some fuel lined that were old and brittle.
Replaced some wires that had some cracking in the insulation.
Put in barrel and started up and adjusted everything
Also rebuilt fuel pump
He found that the motor has a screw on the throttle control the will limit the how much the carbs open up.
So he thinks the motor has never run at full RPM of top speed.
I watched him start it in the barrel and with just a few turns it fired right up and ran great.
All this for only $400.
Can't hardly wait to get it on the boat and in the water.
Now I need to find out what color was used. So I can touch up the paint.

Well that's another big step closer! :D Reasonable outboard service is really hard to find around here, sounds like you have a nice resource there and he took care of all the same things I have had to do to mine to get it running reliably.

1961 should be a Cloud White motor. Color went to Phantom black in 1964 at the same time the cowls took a little different shape. Motors made before 1959 were available in colors

Geez, did you have a gun in the guy's back? You stole that motor for $400.

Great Find!

Now that I have the motor mounted and ran it a little in the lake.
I would like to know what gas and oil mix you all are using in your Merc,
And the year. If that makes a difference.I was told to run a 32to1 mix in my 1961.

Mercury issued a service bulletin in the mid 1960's that said any full needle bearing motor should run 50 to 1 oil mix. Also the 1965 Service Manual C-90-25500 states to run 50 to 1 mix with Mercury Formal 50 Quicksilver oil. However with my Merc 500 I run around 32 to 1, it varies between 24 - 1 and 40 - 1. If I know that I will be doing mostly slow speed running I run 50 - 1 but never on high speed runs. My thinking is the motor will run on 50 - 1, if it is tuned up perfectly however get a little dirt in one carb and you could have two cylinders running at 100 - 1. The guy that told you 32 to 1 was right on. You may have to clean the sparks plugs once or twice a summer no big deal.

Hi Jeff
I have a small runabout similar to the Glen-L Flying Saucer but it is of my own design. I currently run a 1964 Merc 500 and when I go to Atwood Lake I run a Mercury KG-9, because of the 25 hp limit. You can see my boat at viewtopic.php?f=20&t=14659. I do not know Jay Miller. I was just by Seneca Lake last week on my way home from DC. How is that Merc 400 running on your Zip and what pitch prop are you using? If you would want to display your boat, I am have an Antique Outboard meet at Atwood Lake on Sunday OCT. 6th , would love to see it.
Mike

I run my 2 strokes at 50:1 regardless if it a chain saw or an outboard. If it starts sputtering, just add a smidgen of straight gas until it runs perfect and still has some smoke coming from the exhaust. Keep track of your dilution ratio then you can keep that ratio for that engine. I only have to tweak my weed eater to 40:1 but everything else likes 50:1.

Regards
Bill
