Hello,
not sure if in the correct place but I'll try.
I bought 2 years ago a 1999 regal with a 4.3 Mercruiser. Ran great the first and second year. Bought it to take my wife and step kids to enjoy life. At the end of last season my wife and I took it out on the Gulf & started running sluggish. I changed fuel separator and ran great after.

Took it out with step step to check it out before taking the women out and it ran great idling and would accelerate just a smug in fine. But could not go more to get on a plane. However, running slow was fine except had a very slight vibration. I thought ok maybe it's the plugs but it ran fine at slow speed. Just got biggy when trying to accelerate.

I just not pumped oil out of dipstick and it was milky. However on the dipstick shoes normal color. Does this sound like a head gasket or cracked head? Does anyone have an idea of direction I'm leaning?. Thank you for your time & knowledge in advance.

A cylinder compression check should be done so compression is known and remove plugs to check for moisture/water on any of them.if run in salty water, when were the manifolds last changed?
