"I have twin detroits 6-71'
"I have twin detroits 6-71's 485hp. Lately I have been having a problem with my stbd engine losing RPMs. Ran all day yesterday at 1100 rpms on a fishing trip. As I got closer to home, I went up to 1700. a short whilce later, the STBD engine droped to 950 rpms and reved back up passed the 1700 mark to about 1850 then lowered back to the 1700. this problem has been going on from time to time, not always, However, yesterday it happend quite a bit, I had to keep it at 1100 rpms the rest of the way. Any help as to what may be causing this drop in rpms will be greatly appreciated."
