I have a 1996 Bayliner Cierre express 2452.I just replaced the original motor (96 5.7)with a 2007 5.7 .I added the closed cooling system from San Juan Engineering.The heat exchanger sits basicly in the same spot on the top front of the motor as the old one but ,now my motor cover won't close.It hits the exchanger.I even went so far as to cut off the bottom of the new brackets (exchanger support)3/4" and re-drill the mounting holes so as to drop the assembly 3/4".It still hits.Anybody experienced this?All I can figure is the new motor(serpentine belt)is designed a little differently in the front so that the sopports are a little farther forward.Maybe 1/2".I'm gonna call the engineering co. tomorrow.The only other option I can think of is having my cover re-fabbed.THAT SUCKS!
