Sea Ray Electronic Interface Module (EIM) 1587682. Also marked Grayhill 93YY5062-2. This EIM was in storage in a boatyards parts department for many years. The reason it was stored and its operating condition is unknown. This Sea Ray part is known to be troublesome so it can only be assumed that this was replaced due to a problem. Therefore it is being sold as a non working core or for parts and is being sold as-is.
