For those of you who were aware that I intended to bring my boat home 90 miles on one engine I was successful yesterday. 14 hours at approximately 6.5 knots on the starboard engine. 50 psi oil pressure, 150° temp. Engine purred like a kitten. Rear seal on trans leaked as I have not yet got it apart to repair it. Added fluid every 2-3 hours. Now the project begins in ernest. Thank you Commander club members who've given me info and advice.
