Starter issue and leaky primer solenoid

[smkinnan]

I have 2 issues (ok, actually more but this isn't the forum for that) :/

I have a 1984 Evinrude 150:

First problem is when I try to crank the engine, the starter will not "engage". The gear on the top of the starter won't move up every time. It does sometimes if I'm patient but 7 out of 10 times it won't. Once it engages it will crank the engine like nobodys business. Do I have to replace the starter or is something else (a solenoid perhaps) the culprit?

Second issue is the primer solenoid (I think thats what it is called, has the little red lever and a schrader valve on it) is leaking. Is there a way to repair these or do I have to replace it?

Thanks for your help guys. I appreciate any feedback at all.
