Review on DB Electrical 410 44079 Compatible Replacement by George Miller

I don't know what to write or even do. The starter fits my Yamaha F150 outboard perfectly and is easy to install. But when the key was turned, the starter did not turn. All connections were clean and correct, but the starter would not turn. After about 5-7 attempts. I heard him try. like it was just frozen or stuck. So I decided to let my wife turn the key while I tapped it and after a few tries it finally worked. Although now when he started the boat normally we have started it the last 5 times. From the first start it started making a loud squeak like the flywheel didn't disengage quickly enough after launch. maybe because the Bendix isn't moving in fast enough. Waiting for an answer what to do.
