As Bushwacker mentioned here is the splashwell I purchased from Potter (Seamark) awhile after I bought my Seafari in 1976. I added the teak to it to support a Coleman grill when at anchor and it also serves as temporary seat. The cutout in the teak needs to provide enough clearance for the outboard tilted up and a bit more in case the engine bounces on a road pothole.
