There was more bad news that I should have put in the post. There were several leaks that indicated the head had problems and judging by the corrosion it had been sometime since anyone had looked at it. The lower unit appeared to be dripping and the trim tabs would go up but not down. Had I known you were interested in the engine I certainly would have offered it. The Yamaha has been mounted and I should get the boat back tom. to get cleaned up and ready for the water in a few weeks.
