Change your spark plugs these motors like fresh plugs and use copper anti seize on the threads

So replaced the oil in both engines about a year ago.
Notice a few weeks later that there was some oil in the port side breather box.
Air filter looked fine.
Cleaned out the breather box and suspected that I may have over filled the port engine when replacing the oil.

Notice the port engine dropped in rpm, like 2-300 rpm, now and then over the past year but never lasted long so did not care too much about it.

Couple of weeks ago the port engine dropped more severely in rpm, like 1000 rpm, and lasted for about 20 second each time.
It happed on and off for a day.
Suspected a bad spark plug.

Replaced the spark plugs in the port engine this past Sunday, noticed oil in the breather box again.
Cleaned in it out. Old plugs looked old but not horrible and all about equally worn.
Oil level is at the "L" mark when cold and on the trailer. Approximately the same level for both engines. No oil in starboard breather box.

Went for a ride after the plug replacement. No severe drop in rpm but maybe minor drops in rpm a few times.
Found oil in the port side breather box when I got home after the ride.
Also, at one instance both warning lights for overheating came on approximately 30 seconds apart as I was going about 2500 RPM for the last 20 min or so.
Just surprised that both lights came on approximately at the same time as the cooling is independent between the two. Which makes me suspect an electrical issue.

Thoughts on this mess?
Is overflow of oil caused by a bad fuel injector and or bad ECU pushing gas into the oil making it overflow into the breather box or just simply too much oil?
Or something else?
I tried to smell the oil in the breather box to see if it smelled like gas but could not detect any distinct smell of gas but I'm no oil connoisseur...lol.

Any input is appreciated!!

Hey @Konnie I know this isnt relatable to your comment. But we have the same boat, if possible would you be able to measure the inside diameter of the cutout hold for the ancor compartment? i recently bought the same model and it was missing that. Forgot to measure before i left. Boat is 3 hours away and want to order the parts so I can install it next time I go down. Thanks!

Sure, the anchor compartment in front / bow?

My apologies I meant the latch mechanism to keep the door closed. What the internal hole is.

 

[Konnie]

OK, the inner diameter of the whole for the latch mechanism, right?

 

[Konnie]

The hole not whole...

 

[okula225]

The hole not whole...

Long day lol yes the hole for the silver slam latch.

 

[Konnie]

I can’t measure the hole without remove the locking mechanism

Can you measure the silver circle on the inside listed in picture 1? or the top portion listed in picture 2?

Keep in mind that the silver circle shown in the last pic does not go through the hatch.
You can google cut sheets of all the parts for this boat.
It may be easier to see on the cut sheets.
