Trying to figure out which Flo Torq II set is needed for my 150hp 4 Stroke. Hearing two different answers and I'm not sure which it is. I have a Mercury Tempest Plus 23p prop and my existing set up looks more like the second numbered set below. My drive sleeve has some small plastic chips coming out and I want to replace it with the correct one. Any thoughts?
835257Q6 says it's for Mercury 135- 300hp with "surfacing applications" while
835257Q1 says it's for Mercury 135-300hp
Thanks in advance for the help.
