I have a mercury outboard 60hp with the following details, I want the proper mercury manual for rebuilding the powerhead. I have purchased a clymer but its nowhere near as impressive as the VP manuals. I have tried Mercury Express but it does not recognise the serial number which I know is correct as Ive had the engine from new and its on the engine and all the paperwork. What manual should I order?<br /><br />Mercury Engine Serial No.<br />09982646<br /><br />Model No. <br />1-060412UB<br /><br />Year 1998
