I have a 2003 Honda 115 and have a couple of questions;<br /><br />1. On the transom I have what appears to be a gas filter... its has a clear plastic or lexan cover with a paper filter inside. Does the cover of this filter screw off to replace the filter within.<br /><br />2. Can any brand lower unit lube be used for the lower unit. I have some lubrimatic lower unit lube and would like to use it.
