Did you measure the Temperature of the Exhaust Elbow and the Oil Filter?
The oil filter should be about 80C when the Onan has warmed up to operating temperature. And the exhaust elbow about 50C.
If the exhaust elbow is higher than 50C, there is a restriction or limitation of seawater flow. Other than the things you checked, this can be caused by a build-up of carbon in the exhaust manifold and exhaust elbow. Did you visually check the impeller?
