45hp mercury need help identifying what year and model? Number on plate on trim

[Bmoneys]

 

[racerone]

Not very clear.----What is that number ?

 

[Bmoneys]

It looks like 5588388, I'm not sure or the 2 8's after the 5's could be 3'. It's not clear

 

[racerone]

Post a few more pictures of this motor.----Cowling , coils , carburetors , fuel pump on the engine included.

Ok I will i when I get time. I just have bought this engine and found out afterwards cylinder 3 has low compression around 80 and leaking. Weighing the options if I should rebuild it or not.

 

[racerone]

The serial # is not found in the 45 HP model years.----Seller was not honest I think.

 

[Bmoneys]

Yeah the front of the motor says 45 . Once I get some more pictures I will upload them.
Thank you

Here is the updated picture of motor to determine what year and model this motor is.

The one picture shows a label ----1980 50 HP -----So seller may have put a newer cowling on it.----Serial # also clearly makes it a 1980 50 HP.-----Will be hard to find a shop to rebuild it for you.----It would shock you what that would cost.----Your location?

 

[Bmoneys]

I thought about trying to build it myself, I have never messed with boat motors. I'm not sure, if I could still get parts for it. I live in GA.

 

[racerone]

parts are not a problem

 

[Bmoneys]

What is the problem then?

 

[racerone]

Motor needs to be torn down for inspection.-----Then evaluate condition.----Look for parts.----And before you ask , it cannot be a blown head gasket.----There is no cylinder head on this motor.----Only a water jacket cover.

 

[Bmoneys]

So it sounds like it could be the rings sticking or broke ring.

 

[racerone]

Remove the 4 intake bypass covers on side of block.----Just 2 screws each I believe.-----Allows you to inspect for broken / stuck rings.----Allows you to look for scored ( damaged ) piston.

 

[Bmoneys]

What numbers of the serial number did you type it, won't work for me says it's not found?

 

[Bmoneys]

I'm think about getting one of the mercury books to learn about this motor and how to rebuild it if possible

 

[Bmoneys]

I appreciate your help racerone. I can you use all of your knowledge.

 

[racerone]

I simply look on the list that covers your serial number!!----I do not enter the serial number in the hope of finding an answer.----Good luck with learning about this motor.-----Easy fix here as I have good " donor motors " for parts.----Your location ?

 

[Bmoneys]

What is the serial number to this motor? Easy fix for you must do it all the time. My location is rome ga

 

[racerone]

???---See post #3 for your serial # , I think you posted it.

 

[Bmoneys]

5588388 was this correct bc it was not clear to read on the motor. Where are you located?

 

[racerone]

About 1000 miles away.

 

[Bmoneys]

Yeah thats a little to far lol.

 

[Bmoneys]

In the pictures I submitted what 4 bolts are you talking about removing?
