hello.i have a 19 foot 2001 bayliner capri...when I leave and return to the marina,its real shallow and I trim up all the way until it stops but haven't trimmed up with the trailer button,(which can go way up)...im just off idle in fwd.. im not sure if its wise to trim up any higher than just with the trim button as I don't want to break anything ..i never had to do this but im at a new marina this year and at low tide theres not a lot of water. thanks
