please I'm debating my mechanic on timeing. HELP!

Hi, I'm back for another season of great advise. I have a 78 merc 115 more of less,it has somenew parts but anyway. My mechanic(who I think is losing his touch)insists on setting the timeing to 27 degrees. Everything I have read says 21 degrees. The motor threw reed valves through the block three times last year. Doe's anyone know why he would set the timing so high. Should I set it back to 21? Please help. I give up on my mechanic. He is retired now and I hear he enjoys his wacky tobacky a little too much. Thanks for any and all thoughts on the subject.

Ive heard that the 115s are sensitive to<br />timing,plug heat range and octane.<br /> Check with the guys at Johns Old Mercury Web Site<br /> at: www.pfs-ware.com look around,great forum and excellent links.My manual that only goes to 72<br /> indicates 23 degrees.

Rod Knocking's got the hot ticket. If you want it at 21*, that's where it should be. Sounds like your wrench is getting a quanity discount on pistons.<br /><br />c/6<br /><br />Hooty
