    propshaft endplay - 82 Mariner 90HP

    I was just changing the prop on the above mentioned motor and I noticed you can push the propshaft in toward the pinion gear a slight amount.

    The owners manual for my '82 Mariner 90 HP inline 6 states to mix the oil at 50:1, but on several other boards, people have been saying that 50:1 is inadequate and I really should be mixing at 40:1, regardless of using dino or synthetic....what do you guys mix at?<br /><br />Thanks<br /><br />James

    '82 Mariner 90 HP Carb set up questions

    The manual is a bit vague regarding setting the idle speed on the Mariner mill. It talks about loosening locknut on cable barrel and adjusting it that way. I'm not quite sure?? Is it taling about the hold-down where the accelerator/shift cables come into the motor housing? The motor runs great...
