Hi Folks,<br /><br />New here today, so appologies in advance if this is in the wrong topic.<br /><br />I have acquired a mongrel Mercury / Mariner OB which consists of a grey Mariner leg s/n 6074133 and a 70HP Mercury power head.<br /><br />I need to order spare parts, but try as I might I can't find a serial number on the block. I've tried looking for welch plugs with numbers stamped on, but can find nothing. <br /><br />The only thing I know about this powerhead is that it is a 3 Cyl, twin carb, 2 stroke. <br /><br />I'm told it's between a 79 and an 83, but this may be incorrect. Judging from the condition, it's certainly no newer than 87.<br /><br />I've removed the flywheel and can find the stator (which is what I need to replace) has a p/n 398-5704A4<br /><br />Can anyone please help me by either guiding me to where the s/n would be stamped or by helping to identify the engine series.<br /><br />Thanks

Thanks AMD ! That narrows down the leg, but I'm still none the wiser where to find the s/n on the power head. Anyone help ?

Thanks Outbored, it would help except that with this motor I can't be sure the cowling is the original for this power head, in fact, it can't be as it's definately a Mercury head with a Mariner cowling on it.<br /><br />What I really need is someone to guide me to where the number would be stamped on the engine.
