I have a Boston Whaler with two 1994 225 Yamaha 2-strokes. It sat for a year or so. After getting engines running we took it for sea trial. Both engines need idle adjustment but the starboard engine, when put in gear, will only go to about 1500 rpm. As you increase power/speed with the port engine the starboard will come up to 2500 because it is being helped by the port but when you pull back on the port the starboard drops off to 1400-1500. In neutral it revs to 5000 with no problem. Anybody have any ideas as to what might cause this? Thanks. Alfy09
