How to relate outdrive trim angle to Garmin display trim percentage

An outdrive can only be trimmed out to a certain angle to avoid damage to the u-joint assembly and engine coupler while running above 1000 rpm. Since a Garmin display may present trim percentage, this video shows a method to correlate the two values (percent versus angle).

Go here and enter the serial number of your drive to see what type of documentation is available for it. www.volvopenta.com/your-engine/manuals-and-handbooks/ What I actually show in the video is the 'Operators Manual'. Typically those are available for free download from the Volvo Penta site. If not, you may have to purchase it. I have also purchased a hard copy of the the 'Workshop Manual' for my drive through the site. It is part number 47713910 for my drive (DPS-D1). Don't take my word for this part number though, depending on what drive type you have. Enter your serial number, and the click the 'cart' button to verify the part number. Hope that helps! Let me know if you have any other questions. Thanks, IB
