Identifying types of wood
 

I have a 26' Penn Yan Tunnel hull and I am refinishing the exterior wood, handrails, swim platform, exposed top, etc. It is either teak or Mogohany but I don't know how to tell which it is. Any suggestions? I was going to assume it is teak and use a teak restore. If it becomes appaernt that is not working I was going to sand it and refinish it as if it was Mahogony.
