this is not really a problem but actualy a question. I have an omc 460 with thru hull exhaust. I am sick of my girlfirend complaining of the noice. I would like to have the optioin of silent choce. I have a Y shaped pipe that i was told i can install and the exhaust would exit out the drive like any normal boat. I want to get the manuel silent choice with a T pipe and a valve that can swith silent or thru hull. My question is right now the water from the engine exits through the thru hull exhaust. If i change it to exit out the drive will I have to do any other adjustments. I dont have a hole that i am aware of on my drive for the water to exit. what do i need to do?? i cant stand the noise from my boat or my girlfriend
