We recently acquired a large inventory of overstock items. These items are missing the manufacturer’s original packaging and may have minor cosmetic blemishes from storage (see photos).

We understand R&D Marine part number 800-030 is commonly listed by manufacturers and dealers as a 3/4" stud engine mount. However, the mount we have in stock does not appear to match that specification. The stud measures approximately 5/8" outside thread diameter, and the included nut also measures approximately 5/8" inside thread diameter. Based on these measurements, we believe this is actually a 5/8" engine mount that may have been mislabeled at some point, either by the manufacturer or after distribution.
