Cruising in my 1993 18 OMC 351 this weekend, noticed that during high speed runs engine ever so slightly trimmed down on it's own (that is, toward "bow down" on the guage). What could cause this?
Also, I noticed that the trim tab on the outdrive was set at No. 5. The operation manual says No. 3 is the optimum. What do you experts think? Thanks.
