My son left his boat here at the house, and as it has been too windy this spring to go outside much with my 25 footer, I am thinking about using his boat and fishing the inlets and ICW. He has a 17 foot Dixie with a Evenrude 90Hp V-4 VRO. As I only have manuals for the 40hp on my skif, and for the 5.0L OMC stern drive's on my big boat, I don't have a clue about his engine.<br /><br />How do I check the oil on his tilt/trim. Where is the fill plug and where is the release screw. Oh yeah what king of hydralic oil do I use. The engine is an 1985 or 86.
