Customer Question

Jason, I just put a new 7.4 liter TBI Motor in my Boat. its a 97 Chaparral. I bought it from a guy who left water in motor and cracked blocked. motor had less than 230 hrs so we did basic rebuild bored used block .30 over and install new pistons rings and bearings and simple valve job in heads. I need to set timing. I dont have that marine diagnostic tool to get motor into base timing mode. Can I use the jumper like on carburated models since its just a TBI or do I need a diagnostic tool. if so can I buy one from Auto parts store or are the different for marine engines.
