I was out using a recently installed fish finder to try and find some spots to fish this weekend. When I first got the boat in the water all was well, until it came time to dock. When I was trying to engage the engine into forward, it simply wasn't going. It was reving up but the motor wasn't actually going into drive. It would go into reverse easy enough but it was acting really weird going into forward. If you would push the control handle to the forward position it wouldn't really do anything. When you actually pushed forward a bit to give it some throttle it would "slam" into gear and start moving. I was reading a bit about a dog piece in a gearbox, but i'm really new to boating so i'm not sure what i'm dealing with. I'm extremely mechanical and feel I can fix this if it's a gear issue, but i can't find the gears anywhere, or this "dog" piece whatever it may be. I'm hoping I don't need a whole new lower unit, only because I can't find those either. Thanks in advance to anyone that may have had this issue and can offer some assistance.
