1963 7.5 HP Mcculloch outboard

[mwsantee]

I am looking for a impeller for this outboard. <br />What type (weight) of lower end oil and how much (oz.) does it take? What is the oil to gas mixture? I have been using 50/1 mixture.<br /><br />MAW

Sierra catalog has the impellers (you have two, 1 for the engine and 1 for the bailamatic system)<br /><br />Sierra cat. says<br />7.5HP: 1960-69 BB# 83009 replaces Mcculloch #73055<br /><br />90 wt. in the lower, and 50:1 is fine.

The Scott guy reccomends 40:1.
