"Hi Guys,

96 Volvo Penta 7.

"Hi Guys,

96 Volvo Penta 7.4 GL PNCA with a DP-S stern drive 1.78 ratio.

Removed last winter to clean up and paint. Went to re-install and got as far as 5/8" apart between the pivot housing and stern drive. Went in smooth and easy up to there and stopped. Shift is in neutral, shaft and o-rings well greased and oiled. The shift cable is fed through the casing and is not binding. The tilt cylinders are up and out of the way so no contact there. The gap is basically dead even all the way around so I don’t believe it’s chocking. I even pulled the stern drive off the jig I made to make sure it wasn’t somehow causing it to bind. I just had it hanging with a web strap hooked to the pivot housing to keep it from falling off. I tried pulling it all the way back out and changing the drive shaft position to see if maybe the coupling joint was chocking inside where I couldn’t see it. I’m not sure if that may be the issue or not at this point. It’s the only thing I can think of?? Where the housings are only 5/8" apart I'm reasonably sure the stern drive shaft splines are engaged with the engine at this point?? Does that sound right? I can't figure out why it won’t go the last 5/8"?? I pushed and wiggled by hand to no avail. I even tried using a rubber mallet to coax it a bit. Am I just missing something simple??

Looking forward to hearing from you!

Did you check the alignment before you tried to reinstall the drive? Don't force the issue you could do damage. Try turning the prop shaft. If it turns you did not engage the spline shaft. With 5/8" I think the spline shaft is engaged. Check the splines for damage?

"Found the problem. One of the new drive shaft o-rings was not the correct size although close enough not to be noticeable. It was just loose enough in the land to roll up when the carrier bearing came up against it. Unfortunately that took me a day’s work to find!! I bought two new o-rings, oiled them up, installed them and the drive slipped into place like butter.

Thank you so much for getting back to me!

While I have your attention, any recommendations for quick change oil change system that mounts in the oil pan?? I’ve been sucking it out but I’m not comfortable with that system.

Thanks again for the response Don!"
