Re: johnson seahorse
I did the same about 2 months ago, except my was a 74. These are very forgiving little outboards...so they say. Mine was very hard to crank and would run for about a minute and die. I spent about 200 in parts. Now she runs like a top. I learned real quick I needed to buy a repair manual...well worth the money. You can buy it here on iboat at the marine store. I drained the gear oil and replaced the impeller and the gear oil and replaced the washers on the drain plugs. Next was a new plastic gas tank, fittings, and fuel lines. Walmart for the tank and auto store for the hose. Then was the fuel pump. Easy fix. Pulled the carb off and rebuild it. Just order a carb kit for your model. Pretty sure you have a carb like mine, Type 1. Easy task even for an amateur. Check your spark with a spark tester that you can buy for about $10 at an auto parts store. You should get a strong spark at 1/4" gap. If not you will need to check your coils for cracks. To check your coils, you will need to remove your flywheel. You just as well change out your points and condensers while you got your flywheel off. Put in new plugs and maybe plug wires. Depending on how long its been sitting up, you may need to decarb your engine with seafoam...especially if you have low compression. Rings could be seized and not opening up to seal up the cylinder to good compression. Check compression should be one of the first things you do. I discovered at the last minute, I did not have a thermostat installed on mine and one should have been there. Another easy fix. There are other things to check out that you will discover on here from other responders and especially in your manual. But you can get all the help you need on here... should you need it. Thats just about all I did and it was worth it. Hopefully I will enjoy my six for a long time. I know much more about it now than I did when I first purchased it. I been taking it out every weekend and enjoying it. Good luck with yours!!!
