Possibly blew an engine - 98 454 Gen6 Horizon

[370]

So it looks like I possibly blew my Port engine as I was cruising along at approx 3400 revs the oil pressure dropped to 10 PSI. I grabbed the throttle and pulled it back in and shutdown in a hurry. I bumped the hatch up a bit while I was still moving and had wifey take a look and when I asked if oil was everywhere she just gave me sad face.

Once I docked I took a look and see the bilge full of oil as expected. Unfortunately we all had to quickly jump in the car to grab the kids so I did not get to investigate much. Hopefully I will get down there in the morning and suck all the oil out and see if I have a new window in the side of the block.

Being that these engines are close to 950 hours on each it seems reasonable to yank them both if I have to replace one and just do both? Not looking to spend that kind of coin but I love the boat and figure it is decent timing with end of season and all. Anyone want to make me feel better and tell me it is just an oil cooler hose or something?

Man I hope its not a blown engine, let us know what you find when you get back to the boat.

remote oil filter lines are a culprit. Let’s hope for that

As far as rebuilding both, the other one could last 1200 more hours or 2 you just don’t know with these things.

I had the same dilemma in my old boat but decided to do one knowing we would sell it shortly after. If you know you’re going to keep it and it’ll give some peace of mind id rebuild both.

I would think if you threw something at 3400 RPM you would have heard it before looking at a gauge.
Good luck. I'm on my last rebuild. More like a replace. Had to get a new block. After this, I'm going electric, and making it a trawler.

Had local mechanic put eyes on it but did not get anything useful. Was told they think it is the oil cooler but they did not pull the deck to look on that side of the motor.

Being that the hoses look original I am fine with replacing them but was really looking for an answer. Once I replace the lines and cooler will throw some oil in it again and see how it goes.

Think I should pull the oil filter and see if I have any gold dust in there? Worried about crank damage maybe so I guess I could send out an oil sample.

I highly doubt you blew that engine. It would have told you that by way of much more than a low oil psi reading. You most likely have a ruptured oil line, failed cooler, or something similar.
