Went with 25's because of different post's that I read and I guess that trial and error is how we find out what the best is (even though it is kinda expensive), but what I found funny is that I have no problem getting on top and that is why I was wondering if the outdrives were going out far enough. Next time out I am going to try the trailer switch and see if that helps. My electric indicators are only reading about 1/4 of the way when trimmed all the way out. By the way,I bought my boat from your neck of the woods, Pittsburg, P & L Boat Sales
