Hello everyone!, I'm located in NC and looking to purchase what I was told is a 1973 Royal Lowell with a diesel motor that appears to be close to a Sisu 22 design. The place that has it now is going through the motor to determine its condition which will I'm sure determine the price they'll ask. I'm sure I'll get laughed at for this but my goal is to clean her up and actually use her for taking on the local lakes as well as the ocean with my wife and kids as its big enough to do so and apparently these hulls ride smooth and plus I love that its unique. Can anyone help identify this specific vessel as well as the diesel motor? I've tried to find this particular motor but didn't have any luck. I was told its a Ford Lehman but would like to know which model specifically it is. Below are pictures of it. Thanks in advance!
