I tried to find something local, but only found the whole starter for 106 dollars here-

http://cgi.ebay.com/ebaymotors/NEW-STARTER-YANMAR-YSE12-YSE6-YSM12-YSM8-/330442614329

The solonoid is a common off the shelf item and should only be about 30 dollars or 70 from Yanmar, but I could not find one. The next thing to do do is use the question box on the link to ask for a solonoid only.

You can also try-

http://www.go2marine.com/category.do?no=14073

that should open to a Yanmar starter. If I find a better site I'll list it here.

Hope that helps.

Thanks, XXXXX XXXXX already bought the same starter from someone on ebay a while back... It seems to be the correct one, same tooth count, same rotation direction, but it almost never engages the motor correctly. Basically it just spins without engaging, and just barely catches about every 6th try. The old starter motor works Great, it's just that I have to jump the hot leads to bypass the solenoid. Starts every time. So anyway, I really just need the solenoid.

Okay, I understand. I'll opt out so one of the other techs might have be able to help.

Thanks again.

graphicHi, Since the new starter doesn't work all the time and old one doesn't work at all. Lets do some voltage checks. Find the yellow/red wire going to the starter solenoid check the voltage 12 when cranking. if low voltage or intermittent primary starter solenoid bad. The solenoid on the starter is the secondary. Check you voltage on same wire while in crank position. This is a test to verify that the solenoid is bad. Strange that 2 different starters have similar symptoms. Here is a start circuit follow the yellow/red wires in this diagram there may be some of the circuit that don't apply to your system.
