Ezgo 1980s Frequently needs a push to get moving. Don't slow down!

Batteries were checked. Dry so put water in. Checked and are fine. Friend says maybe dead spit in motor. He says leave key on in drive and give a push until motor engages. I say connects are corroded. Its an 80s ezgo. Live it but don't want to put 100s in it. And I sure as heck can’t keep pushing it around. Now when I take a drive I can only wave. No stopping for chit chat.? Because it may or may not start again.
