I have a 2000 41PC with the 6CTAs engines. I noticed earlier this year that the starboard engine oil pressure was low after running awhile. I have checked fluid levels, changed oil and filter and it still remains low at idle coming into no wake zone. At 1800-2000 RPMs it is around 30psi. This did not happen until I had a oil remote filter bracket put on. After the latest oil change on both motors, the port is doing the same. At no wake speed I am around 15psi for both.
