    Is Jim Stevens doing the DLP printing? That is looking very good. How durable is it in a wet enviroment?

    Jim Stevens does FDM printing and did those motors for me shown in post #139. The DLP motor in post #180 was actually done by laser guy #2. While his laser has some shortcomings, his 3D printer more than makes up for it. 100% waterproof and lighter than FDM because they can be made hollow. With really cool 1:20 engines available, the basic Atlas hull will do at least a dozen other boats (mostly exposed engine) from 1972 through 1983.

    Now, I have to convince him to do an Allison.....

    Here's the layout. Note small bends in the rudder pushrod.

    Default 1:20 scale Merlin

    This is what it looks like before trimming off the supports.

    Default Found an Allison

    https://www.turbosquid.com/3d-models...-engine/370280

    It wouldn't be difficult to edit the file such that the exhaust was going the other way. While not as precise as the Merlin, at 1:20 scale it would look just fine in one of my little hulls. As you can see, the file is not cheap, so it would have to be worthwhile to buy it.

    That said with the two hulls I've done, a person could build dozens of different boats. The secret one I have in the works was a large boat at 32' so it may only do the one hull. Instead, I may do a Karelson hull which would open up countless more options.

    Default Driveline Completed

    OK, here's the completed 1/32" wire drive. The majority of the driveshaft is actually 1/16" stainless steel tube, but the 1/32" wire runs full length from the stubshaft to the motor coupler. It is only where the driveshaft exits the hull to the nosecone on the strut that the 1/32" wire is exposed to allow a gentle curve in the driveshaft.
