1979 55hp Mariner Manual help

Hi guys,

I'm new here and new the the outboard world. My granddad passed away and i got given his old 1979 Mariner 55hp. Did some research but didn't find much except its also under a Yamaha brand sometimes.

Anyway, the engine has been well looked after and Its supposed to run. But it can with all those old forward controls, cables etc. I just wanted to put new power lines, and upgrade the forward control and put it on a hull i just bought.

Also i wanted to hook the starter up and see if the engine would turn over to check compression and sparks before i do go forward with it, do you guys know where the positive and negative wires go? both on the starter? negative on the top and positive on the bottom? And would anyone know what that fuse holder is for as the fuse inside is blown.



Would anyone be able to help me find a free wiring diagram or a free repair manual for this engine?
It would be greatly appreciated.
Thx
Guy

Post your serial# to make ID easier.Dont think Mariner had a 55hp in 79.I can see one in 84.I may be wrong.

Hi guys,

A bit of time passed since my last post. I finally connected the engine up with the help of a mate. It runs. Will be testing it this weekend. I started it on 100:1 but i'm not sure if i should use 50:1. Would anyone know?
Thx

Also anyone know the colour code or where i can get paint for it? I want to paint it the original color or close.
Thx

Re: 1979 55hp Mariner Manual help

Yes, use 50:1.

Can you double check the s/n as the earliest I can find is:

55 EL 663-31206 - 663-32415 1974

From here:

Need to get the year closer as far as the paint goes.

Ok so i've mix 50:1, I've also drained the fuel in the fuel line just to get ride of the 100:1 mixture

I will be testing the boat this weekend. Not sure how it will go as the boat originally had a seadoo inboard engine. If you guys want to follow the build have a look at this link

Re: 1979 55hp Mariner Manual help

Ok so went on the river today and the boat performed well. I'm very happy with it. Just wandering however, The prop/impeller i got on the boat looks small compared to may mates 40hp prop and i was wandering if i can still get a performance prop for them and where can i get one. Any body have one?

Thx
