@zman my apologies if I offend anyone this thread is just comical. If you can't notice gains swapping octane in a car you sure as heck arent going to in a boat.
I'm not sure completely what you're asking but I gather it's details about my boat. I run a 94' Eliminator Eagle 25' with a mildly built carbureted 454. I'm not lucky enough to have that fancy DI or timing advance or knock sensors.
Yeah my skiing is challenging but it's awesome
