Just finished installing remote oil filter kit on 2003 5.0 Mercruiser...Should have pulled the engine! That is a job that I wouldn't wish upon my worst enemy!
Make sure you get the hoses correct. Dealer put mine on and crossed the hoses. 100 hours later the engine sounded like it had solid lifters. Fillter has a drainback(check) valve, engine recieved no filtered oil from the get go. Bypass opened and engine did get unfiltered oil. Volvo shipped new long block
