I just got my son into wakeboarding, we went out one time so far & the boat (17' bowrider w/ 85hp O/B), pulled him just fine. My question is: I do not have power tilt/trim, all I have are 4 holes with a rod to adjust the trim manually. When we were done for the day & pulled the boat out of the water I noticed the rod was in the highest position. What are the lowest to highest positions best used for? Lowest for better hole shot, highest position better for top speed? Am I correct in this assumption? Or do I have it backwards? I never really played around with it before so I just don't know. Thanks
