Hello all,

I am new to boating and also this newsgroup. I just purchased a 18 foot Sea
Ray Sport boat with a 3.0 L Alpha I MerCruiser I/O engine. Can anyone tell
me what grade of gas I should use? The suggested one in the owner manual
says at least with a octane level of 87. People are telling me difference
things, some say just to use regular, some say to use premium. Should I add
gas treatment into the gas tank too.

Another question is my boat trailer. How do I know its time to add bearing
grease into the bearings?

Another recommendation is appreciated. Thanks in advance.

David
