Also changed to 20W-50 oil. It helped, but didn't eliminate the noise issue. A bit strange, but now it starts and runs silently for about 30 seconds, then has 'the noise' for about a minute. It isn't as loud, nor for as long, as it was. Before, noise was apparent immediately upon startup. Sometimes I thought I had a diesel under the hood. Having an engine that is'full' of oil also probably helps as my rear main seal drips.
ORiely's should have a wix for just about any motor.
I'm glad you at least have some relief and indeed a change in the behavior of the tick. I would not give up complete hope on the filter oil combination. While it may not be a complete fix for everyone I have seen it work more then once.
I've also heard of people running half a quart of marvels mystery oil for a couple of oil changes as well.
Gone, out doing soft recreational past time with overpowered boat!
