Re: information please

Hi, Mercom.<br /><br />Your 1969 25hp uses a 50:1 fuel mix, 87 octane unleaded and TCW-3 Outboard oil.<br /><br />The engine may start with no trouble. Possible troubles associated with the long lay-up include failed fuel pump, gummed up carburetor, fuel feed restrictions or air leaks, or dried out condensers in the magnetos.<br /><br />If she starts or not, you will need to replace the impeller in the water pump. Their life is time limited, without regard to usage. While you are down there, replace the gearcase oil.<br /><br />Things to check in the ignition system include point gap (.020"), clean and gap sparkplugs (.030").<br /><br />You will do no harm if you overhaul the carburetor and fuel pump. Gaskets, diaphrams and seals dry out in time.<br /><br />To many folks the above reads like Greek. If that includes you, get a Repair Manual which will explain it all.<br /><br /> http://www.boatmotors.com/manuals.html <br /><br />Good luck.

Re: information please

I found that model number in the Johnson listing. Not suprisingly it's apparently a 1969 25Hp with recoil start and short shaft. Mechanically it's no different than an Evinrude. I'm betting the original hood was damaged or lost and an Evinrude hood was put on in its place.<br /><br />Plan on rebuilding the carb and water pump. Rebuilding the fuel pump would also be a good idea. But start with a compression check and see what the lube in the gearcase looks like and change it. Gas:Oil = 50:1<br /><br />(JB beat me to it. He must have nimble fingers.)
