I Just Put A Trim And Tilt Unit On My 1989 85 Hp Force And It's Leaking Down At The Valve Body. It's The Older Unit With The Chrysler Emblem For The Trim Ram Cover. I Know There's An Adjustment For The Blow Off Valve But The Unit Isn't Supposed To Be Serviceable. I'm Probably Going To Buy A New Valve Body But I Would Like To Get One More Season Out Of It. Should I Just Run The Allen Screw In A Few Turns Or What?
