Re: trim tab for 79 larson with 898
To answer your question, I am assuming you are referring to your drive unit's trim tab. This is dependent in the drive o not the boat make. So assuming you have a Mercruiser outdrive you would need one only if you do not have power steering. My book shows Merc part number 31640A1 (NAPA/Sierra Supply number 18-6011) for the #1, R MR and Alpha housings.
