Ok people. My 198 has a 150 merc 4 stroke, 23p tempest, and a 4” jackplate. with me alone and light tackle i’m seeing speeds of 58-60. when i get a passenger and their tackle my boat struggles to push 50. this thing drives nose heavy and needs more bow lift. i’m wanting to lower my last hole on the motor and one more hole for the jack plate. think this will help or may need transom wedges?
