Fuel pump question

[nate_evans79]

Hello, <br /> I like many others here have just aquired a 1978 Mercury outboard. Its a Mariner 900. It has been sitting for about 2-3 years, and I am in the process of tearing it down, and cleaning it up. Its on a 1978 Monark McFast 17 fiberglass bass boat.<br /><br /> My question is, I have taken off the fuel pump to replace the diaphram, but I cant get the two parts separated. I took out the bolts obviously, and I can't seem to get them to pull apart. I don't wany to pry on it and mar up the surfaces. Is there any special tricks to get this thing apart? <br /><br />Thanks. <br /><br />Nate.

Re: Fuel pump question

If the bolts are removed, tap the outside of the housing with a hammer

I'll give that a try at lunch today.<br />there shouldn't be any rtv or anything on there should there?<br /><br />Just the gaskets, and the diaphram, correct?

1978 Mariner? I didn't realize that the Mariner name was used that far back. Was that the first year for Mariner nameplates?

From what I can tell it is.<br /><br />Is there somewhere I can search the serial numbers to find out the exact info on the motor?

Re: Fuel pump question

thanks for the help. <br /><br />used a few "health" taps with the hammer, and it finally opened up.<br /><br />Also got the 3 carbs off today, and cleaned them up. <br /><br />I was checking the wiring in several spots and noticed that it had melted together, and had numberous burnt spots. <br /><br />So all the wiring has been removed,(with a single strand left to pull the new stuff through.) and I'm getting ready to pull through new wiring as soon as I figure out exactly what I want and where. <br /> I think that doing it this way will be much easier, and safer. I saved what I could of the harness, so I could use the main plug, and just connect new wires from that point.<br /><br />Looks like I'll be spending some time studying the wire diagrams tonight.<br /><br />again thanks for the help.<br /><br />Nate.
