Re: Starter/Solenoid Problem on 75 Eninrude 25hp
Start this process by disconnecting and thoroughly cleaning the battery cables (both ends)and the battery terminals. While doing that, check the terminal ends to make sure they are tight on the cable and that there is no inner corrosion. Bad connections will cause this problem. If that doesn't fix the problem connect a single jumper cable from the POS battery terminal directly to the starter. Be prepared for a spark and the starter will run. If it now appears normal the solenoid is probably bad. If the starter still turns slow, it probably has tight bearings, bad brushes, or both and is in need of rebuild. Your local auto electric shop (starter/alternator rebuilder) can do this for you.
