    I have a 1973 OMC owners manual and it goes into great detail about using 50:1 with TC-W oil and only using 24:1 with SAE30 if TC-W was unavailable ie Emergency use. A 61 10HP has the updated crank and rods. Besides religious reasons, I don’t see why it would need more oil than 40:1. There are enough people out there wanting to ban 2-strokes, why would we want to give them more reason?
