T350 Mag w/Bravo III
I have a 2008 310 DA with DTS and twin 350 stern drives, Bravo IIIs. When I drop my starboard engine into gear it either barely moves or does so very slowly. I must increase the RPM slowly to get it to engage or get it to operate normally. Really noticeable when backing into the slip. The port engine bites right away when I drop it in gear. Then the SB engine barely pulls or I must rev it a bit to get it to bite. Sometimes you can hear a clunk once I rev it a bit. I don't need to rev it much, maybe up to 850 rpm. 240 hours, serviced every year, always fresh water, seacores. Any ideas what it may be, or what to check?

Cheers,
Lee
