3.0l/lx 1996. This site has helped me so much in the time that I have owned my boat. Thank you all !!
My engine sounds great at idle on the water. I could putt putt (2000 rpm or lower) on the lake all day with no lifter chatter at all. My oil pressure seems low. 15 psi 1000 rpm, never going above 25 psi even at 3000 rpm or higher.
My issue is... 3 or 4 minutes of 25-40 mph cruising I start to hear lifter chatter coming on. I back off too idle, it will continue to chatter for 5-10 seconds then completely go away. Could this be due to low oil pressure,wrong vis oil or oil filter? I plan on changing the oil (20/40 full syn oil,right?) and change oil filter when I get boat home. I'm on the lake this weekend and I could take slow cruises for the remaining time I am here. I hope I'm not just answering my own question by assuming it's just low oil pressure causing the chatter. Before I found this site I changed the oil. I put 15w40 and (car filter)not a quicksilver oil filter on. In my research on this site I have learned that that could be my issue.
Thanks again to everyone that takes the time to help others out on this site.
