Mercury 150 serial number?

[Wckdknight]

Can anyone help me find the serial number on my outboard? I thinks its an '86. Its on a 86 ebbtide

at the very minimum its' a '91 or newer (block design).. i'd venture ta say its later than '91 'cause tha carbs do not have external pumps on 'em.. might check here for serial number (pic below).. some do and some don't have it there?.. looks ta have an FF stamped on block half?.. there should be a date stamp in same general area (as FF) at base of number two on block half...

If thats on top then mine doesn't have it.

yeah.. not all have it there.. if not there or on tha port side block half flange its probably a replacement powerhead.. they don't get a serial number.. it will have a production date on it though so you can verify year.. it will be on tha flange or at tha base of number 2 cyl. on tha block half.. might be hard ta see but its there.. will be 1/8" numbers M/D/YR... kinda right behind tha bend in tha timin' arm...................

there should be a "double letter" stamped on tha flange also.. it will tell what motor it is (150 etc.)
yours looks ta be "FF".. will be a 200

most gearcases from 135/150 HP V6 motors should fit that motor.

BTW the powerhead looks like my 1993 135V6. It has a gearcase from a 1988 150HPV6 on it.

ya might wanna figure out what ya got first.. different gear ratios.. 2.0 motors have 2 ta one.. 2.4/2.5's most have 1.87 ta one except XR4 and some XR6's have 1.78 ta one.. Make sure it doesn't have a pre-load pin stickin' out tha top of drive shaft..... although they all will bolt up.
