As I can imagine a lot of first posts are for seeking help, I'm unfortunately going to be no different.
Very long story short, my neighbour left this beautiful thing abandoned in his backyard for 6 months. I spoke to the landlord and he said I may take any of the obviously neglected items from behind there, and this is where my story starts.
Introducing the Hydra-ski! https://imgur.com/60jeAf1
A bit of background from me: Many many many moons ago my Dad used to own a house on a lake in South Africa and we had a speed-boat with a 200hp Mariner on it. It was a beaut. I was about 8-10years old at the time, so I don't remember too much, but it was the start of me loving boats and outboards. Fastforward to now, I'm 25years old, I'm a software developer, and my main hobby is golf. So, far from anything that actually requires the use of my hands. However, I'm not shy of a challenge.
So I got the boat in my driveway, gave it a scrub, and now I've got this: https://imgur.com/uBpZlk0
Boat wise, I'm not too fussed as I've figured most of it out without hassle.
Outboard wise, I'm at the mercy of you guys.
What I know so far: It's a 1980'ish Japanese made Mariner. 2 stroke, 20hp. Exhaust comes through the prop. Googling '6a9 outboard' seems to give the nearest results to it, but no direct matches. Here's the only label on it: https://imgur.com/sUtOxXU
I'm trying to get this motor to run because my ultimate goal is to actually take this out on the water. I've never seen anything like it and wouldn't want to just hand it off to someone to let them have all the fun.
What I've done so far (Please note that 99% of my knowledge comes from either reading about it online or YouTube):
* Check the stator's resistance (resistance seems near to similar engines, but can't find manual for exact reading)
* Made sure the kill switch was working as intended so that it wasn't shorting out the ability to start the motor
* Cleared out the fuel filter
* Cleaned the carburetor to the best of my ability with carb cleaner
* Got a new fuel line, fuel tank, and hooked it all up
* Replaced the gear case lubricant
* Bought marine grease and greased what I best found I should
Once I spent about a good two days of researching, watching online, and fiddling, I got it to start... using carburetor starter spray. I went back to checking fuel filters and such and realised I could've done a better job as I had the dark tea colour fuel. Once I cleaned it again, I got it to start and run under its own power (with muffs on, of course), for about 30 seconds. During that time I observed a milky, and oily to the touch, liquid coming out the prop area. It was a reasonable amount of liquid coming out and it was quite consistent. From this I then read up that it's possibly because I'm getting water in the oil and it's causing it.
So here's what I'd like to ask:
1 - Is water in the oil/fuel mixture the result of water getting in there, and does this mean I should replace seals? (I'd have no idea which ones to target)
2 - Could anyone recommend a place to query about a motors manual this old? I've love to be able to test the cylinder pressure or maybe replace the carb (but I've got no idea of fuel spray rate that it would require).
3 - Any advice for things I should check/learn about?
4 - What should I name 'it'?!
Many thanks!
