The trim motor runs a bit before the motor starts to move. When it its moving sounds bad like low on oil.
I checked the oil level as soon as the plug was lose air come out and oil. So it was full. I checked it per the manual.
Is the pump going bad. What do I check next? The manual I bought on this site said to look in manual 520213 for repairing.
any help would be great what to do next.

Thanks
