power trim fluid type????

[70mustang]

Greetings,<br />I have a Merc I/O 181 ci 4 cylinder. I have a conflict on which type of fluid I should use in the power trim unit. My Seloc manual refers to both 10W40 and transmission fliud. Which is best? If it is AFT do I use Dexton or Type F?<br />Thanks in advance.<br />Marty

Well, that engine was used from 1968 and is still in use today. There have also been several different types of pumps used.<br />Suppose you could give us the year of your setup?

10W30 or 10W40 motor oil.<br /><br />Yes you have a Gen II. All Alpha drives after 1991 were Gen II. Here is a link to the Online Mercruiser service manual for your outdrive. You may find it handy.<br /><br /> http://www.boatfix.com/merc/Servmanl/14/14cover.pdf
