for me it was a no brainer... I was able to get OEM mercruiser off of fleaBay for $30 each
So this is why I was getting confused about the Spicer part number.
Per Marine engine:
Cross & Bearing Fits Alpha One Gen II (s/n 0D870000-0M400411) [260HP or less]
Mercury Quicksilver 805536a 2 - Cross And Bearing Qpd=t* is equivalent to parts:
- 18-2097 Sierra Marine
- 9-72406 Mallory Marine
Mercury Quicksilver 865496a02 865493a01 is equivalent to parts:
- 18-6406 Sierra Marine
- MR-931 OBR Red Rhino
- 865496A02 Mercury Marine
All of the crossreferences for spicer parts are just for the one part number. From what I can tell from this thread the spicer parts are close but not equivalent to the 260HP or less marine parts, meaning they are definitely not up the 300HP needs. In my case I have the 275 HP mercruiser.
I'm not even certain that I need ujoints, but I've noticed that my sterndrive makes a little bit of noise unless it is almost all the way down. .
