Looking for some advise (encouragement actually) on replacing the water pumb shaft (OMC Part 909753). Model 302FTHRCNC Vert Drive: 982740.<br />I have 2 concerns: First, if the splines are worn down on the pump drive shaft should I expect to have to replace the mating upper drive shaft as well?<br />The second concern is one of part id. This is not the orginal outdrive unit as it was replaced with a used unit from a V6 OMC unit (insurance company deal) and mine is a 3.0 4 cyl unit. My OMC service manual and parts catalog is for the original unit. Will OMC part 909753 (pump drive shaft) fit either unit?<br /><br />What kind of surprises should I expect when I start the replacement? As I mentioned above, I did a drive shaft replacement in the Intermediate Housing and survived it.
<br />Plan to replace the wp (kit)as it has not been replaced by me but as I mentioned it was a replacement sterndrive about 8 years ago and have no history for it before that.<br />Thanks again for the reply and encouragement... I enjoy working on 'stuff' but like to know what to expect (besides what the manual says)
