Question:
Just bought a 1977 70hp Johnson that runs good. I want to service EVERYTHING to ensure it stays running good. What should I replace and service on it? Pumps, oils, everything! I don't know much about outboards so please be specific as possible. I have a boat mechanic, I just want to tell him what I want done. Tax time so money isn't the issue! Thanks for all your help!

Just take it to your mechanic and have him check everything. Have him replace the lower unit oil and he'll know if there's water in it that there's a seal or two that will need replacing. Have him give it a full tune up like replacing spark plugs and checking the points and replacing if needed. Have him check the compression on all cylinders (70 HP Johnson I think is a 3 cylinder). Have him replace the air filter, clean and lubricate the carbs and throttle linkage. It's going to cost you but it will be well worth it in the long run.the only oil would be in the lower unit. Change that with lower unit oil and take off the lower unit and change the water pump. As the other answer said if you see water in the lower unit oil you may need to change the seals. Change the plugs, I don't think they have points that year. If its running good there is not much else to do except grease the steering shaft also. You may want to change the fuel pump also as a pm.
can you buy hammerite paint in a spray can or just tins and where would i gt it if i can in a spray?
1977 ? thats a mighty tired motor, you only get about 10 years out of an outboard due to their high reving nature (5500 rpm), do plugs, lower unit oil, water pump, thermostat, if this engine needs anything more than that for work, throw it away, you'll spend your whole summer fixing it, would'nt you rather be out there boating ? I would look for another motor, this ones on its last legs for sure.make sure timing is correct, clean carbs., r/r impeller and gear lube, r/r any hoses that look "tough", check prop bushing, check wiring harness. $250-$350 labor then add parts.
1977 is probably not a tired motor at all. I have a 1955 Evinrude that I run weekly. You can get decades out of a well maintained outboard. Begin with a compression check to make sure all is well with the rings. Plugs should be replaced. Water pump should be replaced if you don't know the history on it. Carbs should be cleaned to make sure varnish does not clog a main jet, as this will lean out the engine and may burn a piston. Change the fuel filter. Gearcase oil is a must every season. If the starter works well, don't worry about it. If it's questionable, I get them rebuilt (usually around $80).
What should I bring on a boat trip?
Good luck - it should be a good motor. Johnson/Evinrudes have always been the best.
Has anyone seen that ship that submerged 1 mile of shore. It's the msc napoli?
if your storing it fog the engine make sure spark plugs are in good shape and that the float is still working properly and fill the gear box with new oilMore Questions & Answers ...
