Need advice on Mercury 75 2stroke problem

[MBay Pete]

Cleaned the battery terminals, gave it a try - no go. Battery shows full charge. Tried Matt's suggestion of the pull start and fired up first pull (So simple, sometimes the simple things are not thought of), motor ran perfectly. Gave it a run to warm it up and then tried the key start - 5 tries and perfect start every time. Now I will check and clean the connections for the solenoid and the starter and see if that makes a difference, if not will get the solenoid and starter checked to make certain they are ok. Thanks to all who offered suggestions and especially Matt for the simple suggestion of the pull start.
Regards to all

You may have corrosion inside one of the battery cables so you could connect jumper leads from the battery to the motor and give that a test.

It sounds like you've been there & done that Steeler, even mentioning the tiny droplets.

Yeh had a few Mercs and Mariners over the years do this. Still wouldn't swap a black one for a white one however LOL.

If that’s the case maybe look to see if the starter motor doesn’t need new brushes or something along that line

If your model utilizes the same style tilt & trim solenoid as the starter solenoid then why not try one of those and see how you go.
