OK, <br />the book says to use EP 90 for my gearbox on my lower drive... Extreme Pressure<br /><br />Everyone looks at me like I am crazy when I ask for it??<br /><br />Is regular 90 weight gear oil OK?<br /><br />What tool is used to pressure test the lower unit?<br /><br />1976 Chrysler outboard. 35 horse..model #35741 serial number 2929.<br /><br />thanks
<br /><br />use pensiol gear lube marine! it works alot better
