    Merc outboard serial number question

    Still curious about the block stamp. Only ones I’ve seen any reference to is the j block, and then one forum page that talked about a circled ‘C’ stamp block (didn’t really read into this one as it wasn’t what I was looking for). Otherwise everything else was later blocks with the double letter...

    Merc outboard serial number question

    Found an entire kit online. Hopefully I can get to it before it’s gone. Right around 1k. Full block rebuild kit with pistons, rings, gaskets, bearings, needle bearings, etc. and it comes with the newer part number power port pistons. Be fun now that I know what I’m doing off my other outboard...

    Good thing I make a habit of doing it every 1-2 yrs. Usually annually. Better safe than sorry. And I always look back when I start up the outboard to make sure I got that steady stream going.

    Merc outboard serial number question

    And another loop back on the block, as I only found this block part number under my serial range for the 150 (marineengine.com) would it have the power port cutouts on the block? And would replacing the pistons to the newer ones with power ports allow that feature to work? Sorry to beat a dead...

    Merc outboard serial number question

    Here is a couple pics from the scope. First is that melted rice section, which is only on the exhaust side and doesn’t seem to have any additional scoring outside of norm. Second is a pic of the intake side. Yes, they are not ported. This side shows how all the others basically look with various...

    Merc outboard serial number question

    I may be looking for a set anyway as I’m not happy with the cyl 1 piston face. Kinda looks like metal rice melted to the surface on one side, but just carbon and oil buildup on the other. The remaining cylinders just look oil soaked and have carbon buildup. May crack the case due to some very...

    I’ll take a look through the spark plugs. Haven’t refreshed the rings with oil yet so I don’t want to turn it .

    The sleeves are in the holes. It just wasn’t a great picture

    Is this what you mean by the power ports? Runners look super clean and piston skirts from what I can see without turning it are also in beautiful shape. The outside of the block is really dirty though whole block is black.

    Yours is a replacement block. They won’t have a serial number stamped. Did find something about that on other forum and site searches myself.

    Merc outboard serial number question

    I noticed the block has an “X” stamped just under the part number on the block, but can only really seem to find reference to the J blocks online. Is there anywhere that has reference to these letter stamps? Wondering what the X stands for and what others there are?

    Merc outboard serial number question

    Just got done looking it up and the 5264 block was only used on the 150 in that serial range. The 115 closest matching part number ended in 5254 in that serial range. And the block serial matches the bracket plate serial. Looks like a previous owner was going for the sleeper look lol. Thank you...

    Merc outboard serial number question

    Any noticeable difference other than the porting to tell the 115 from the 150? Just curious. I’ve only got experience with my ‘68 650 so far.

    Merc outboard serial number question

    I plan on tearing it down some including a rewire on the whole harness. And new plug wires, clean out the distributor, clean out the starter and replace the contacts. Did it to my 650 as well minus the contact replacement. I haven’t tried turning it yet as I want to try to refresh the rings with...
