Movie Muscle

I just bought a 298 SC in the fall and it had not wiper motor or wiper arm. The owner had removed it and I have no clue what manufacturer's part was originally in there or wiper arm size. The top access panel in the head was out and motor removed to be replaced I assume. All I have for reference is the size of the hole drilled in the deck and a small screww hole that stabilizes it and stops the motor from moving. Anybody out there know? Perhaps the factory support guy on here could chime in? Thanks a bunch guys.

Local marine upholstery shops will be your best bet. Also more cost effective. I doubt Monterey is still selling the replacement carpet after 8 years.
