175 johnson outboard

Replaced starter, and after starting, the starter continues to turn even when key is turned off! only way to stop it is to disconnect battery. Could it be the solenoid? Any help is greatly appreciated.

it could be the solenoid it could be that its stuck and letting power to the starter

thanks I think I'll try the solenoid next.

It's been a LONG time since I dealt with an issue like this, but....

I remember on "some" solenoids, there is a internal bypass switch, which was originally provided to bypass the in-line ignition resistor, to pump the voltage up on the Coil, while cranking the engine only.

Could this be an issue of mis-wiring, where when the solenoid engages, it latches the solenoid coil closed, and the only way to release it, is take the Batt terminal off.

That's a long shot !

Have a good Day !

PS: I just thought of something else...
Try reversing/switching the Battery and Starter Main Cables on the Solenoid (large posts).

i think thats a good point. also, in case you dont know where to buy, try this shop www.mcmarine.net. really good parts and very fast. if you cant find what you need contact them, they are really friendly people. www.mcmarine.net
