Welcome to the new Wizard Outboard Forum.
VS200 2238 is the model of the power head, not the whole boat motor VS stands for "vertical shaft" 2238 is the variation of the 2000 series VS200 motor. this variant used the #2377 crankshaft I wasn't able to track down a serial number date but I think serial numbers varied by engine model numbers and not by date so much.
