The engine is currently being stored under cover in Reedville Virginia near the mouth of the Potomac River. It was running when I removed it to install an electric drive in my sailboat. About seven years ago the engine was overhauled, getting valve quides and a good cleaning. The overhaul was necessary because of valve fouling due to bad fuel (bugs). The engine was salt water cooled and the oil is added near the flywheel and measured with a dipstick near the distributor (rear). Since I used the engine only for getting off and on the dock I decided to convert to an electric drive which requires much less maintenance than a ICE. Since the electric drive is working out extremely well I have put the engine up for sale. You can contact me at my work phone: 804 675 5525 if you desire.
