The old 1968 Chris Craft Express 31's engines needed a little love. They are Yanmar 4LH-DTE's that have plenty of life in them. Phillip Sykes tore them down, fixed, cleaned, replace, sandblasted pretty much the entirety of both motors.
Phil's been a hermit all winter, working on the boat. All that's left is put it in the water and ops check it.
While the engines were out the inside of the boat from the cabin back got an overhaul.
I installed 1.25 inch seacocks. I got rid of the internal strainers and went with external type. I also added flush adapters to the raw water inlets.
One thing I noticed...No seacock on the thru hull for the raw water intake??
Very, Very impressive!!
