I, too, have a 3gmf. When I had transmission problems (transmission not fully engaging, and I had to go to reverse and then forward) I had to add a shim inside the transmission. That corrected the transmission problem of not engaging properly, which was caused by the "in and out" play.
Alan Bergen 35 Mk III Thirsty Rose City YC Portland, OR Hi all, When the dive service cleaned my hull last week, the diver informed me of some in-out play in the shaft. I have a 35-3 with the 3gmf and a dripless seal. My question is what are the common causes for this and is some play normal or am I facing a potentially catastrophic problem. Any advice is greatly appreciated. Thanks, Kris O'Brien S/V Syzygy
