    Use any TC-W3 outboard oil for mixing fuel and any gearcase oil labeled for outboard gearcases.

    No oil filter on a 2 stroke.

    I POSTED WRONG YEAR Its a 1982 not a 1985 - if that makes a difference or not.....Thanks for your response.In the interm of aquiring a mechanical manual ( can anyone reccomend the "best " one) ??? If someone can copy and email me the reccomended service schedule and locations of components on engine I'd be very grateful.I want to change the fluids and just give the engine a quick once over before I put it in the water for the first time.

    Also,while I'm here this motor is mounted on a 1982 17 ' travler boat,sitting on a dual axle Holsclaw trailer,pictures included here.
    The boat was stored inside a garage up in the northeast and only used for a couple of weeks each summer.Any info on boat and trailer including how to match the original blue paint color on trailer ??? I know both companys are out of bussiness but thier products are still being used..
    Thanks for all responses
