All,
So I took my 320 DA out this weekend for the first time in a month or so. Last time we were out the boat ran great.

The boat boat started fine and ran well at dock neutral even while throttling up. As I left the dock and went to open it up the port side engine was struggling to get up above 1500 rpms and an alarm (sounded like oil alarm) to me began going off. When I brought engines back to idle speed the alarm went off. I was able to slightly increase the speed if I increased atarboard engine throttle first.

Took boat out again yesterday very short trip. The alarm sounded immediately. Also the psi on dash was very very low close to zero? I don’t have manual but I am assuming that’s oil pressure. Is that correct.

The port engine in question is a total rebuild less than 200 hours.

Any suggestions? Please tell me this won’t bw devasting to my check book.
 
Did you check the oil level? When was the last oil change? Who rebuilt the motor? Is it a Quicksilver rebuild? Otherwise could be a bad rebuild....
 
I doubt you have a fuel pressure gauge at the helm unless one was added aftermarket. Sounds like oil pressure if you have a gauge reading zero in PSI.

Don't start the boat again until you 1.) check the oil level and 2.) find out where the oil went if it's low.

Have you changed the oil since the rebuild? Did you get the proper amount out?
 
Oil was tested and changed last year during the survey. I'm not sure what a quicksilver rebuild is but it was a total rebuild which cost over 10K. Could it be something as simple as the oil pump?

And now I'm worried.
 
I see you are on LKN, was the motor rebuilt locally or did you buy a rebuild?
 
bought with a rebuild. Had the boat for a year now. No previous engine problems.
 
Also I seem to have good oil pressure while running in neutral. I never got up over 1500 RPMS while in gear before the alarm sounded.

I was out on the water while this happened and ran back to dock at 1000 RPMS. How much damage could I have done doing so?
 
Check your oil level first... And then check the oil sender could be clogged....Hope you have no oil or sender is clogged...
 
All,
The dipstick broke off. Any suggestions on how to get it out so we can check the oil?
 
I'm really not sure but you can try getting the oil pump that goes around the dip stick and try to suck the oil out... Maybe it will come up far enough to grab it with needle nose.... Oil has to come out anyway if you chose to change the oil tube.... Or you can leave it there and use the other side.....
 
If I remember right there should be a clamp about halfway down the dipstick tube. Disconnect and the whole dipstick tube slides up and out.
 
UPDATE! Each engine actually has two dipsticks so I think we are just going to cap and leave it in there for now. So the engine was actually very low on oil. The mechanic added a few quarts. Oil pressure is back up where it needs to be and she ran great over the weekend. Thank you for all of the advice and help.

No on to the next problem!
