Hello all, I am new here and am in need of your expert advise. I just purchased my first boat a 1986 19' cruisers lazer 1900. it has a 305 mercruiser with an alpha one outdrive. I am looking to upgrade the exhaust. not for performance gain, just for more noise, I love this boat but its too quiet. I know nothing of boat exhaust so could use some help here. I want to do a thru hull exhaust, but don't want to spend a ton of money. what will I need to complete this project? any help is greatly appreciated!! thanks in advance
