Not shifting

I took my boat to the shop last weak because after running it I found water in the lower unit. After pressure testing it the prop seal was bad. Picked the boat up from the shop and headed to the lake. I backed it off the trailer to head to the dock and it would not shift into forward. The engine would rev up but not go forward. Reverse works fine. I got it back on the trailer and took it back to the shop but he had already closed. Could have a cable not gotten hooked back up or what could be up? Worked great before taking it in.

I didn’t know that kind of thing happened to other people. Man that is really sorry service, where did you take it?
