Hi guys,<br /><br />I'd be very grateful for any info you guys can give me on the following Merc serial number<br />2839467<br />115hp 6cyl inline 2stroke 3carb<br /><br />On mercruiser it does match on the carburetors<br />My carbs<br /><br />What year was the engine manufactured?<br />I see the main jet sizes vary from (mercruiser) .062 -> .068. I'll probably go for a happy medium to lean (for altitude) to a .064 or .066<br /><br />What's the engine capacity?<br />What's the WOT rpm for this engine? And the redline?<br />I figure this is a cross-flow engine so the max timing advance would be 34 deg?<br /><br />Lastly... What is "hole shot"? I've seen it being refered to... Can someone explain what it is?<br /><br />Any other info that is "nice to know" or relevant will be greatly appreciated.<br /><br />Thanx!<br /><br />My searches show that the year of manufacture is 1970. Is this correct?
<br /><br />Thanx for the displacement figures!<br />I'm not all that worried about the main jets, and have already ordered a set (Leaner than standard). Can you confirm the standard main jet size from your manual?<br /><br />Can you perhaps give me the recommended wide open throttle rpm for the engine?<br /><br />Thanx!<br />Leon
