2000 310 SA 5.7 V drive oil press loss, engine removal?

[Jetgod]

Hi all. I am having a heck of a bad go with my port engine and need some questions answered. I have had some water intrusion on the inner port and starboard cylinders resulting in valve damage. At a minimum I obviously have to pull the heads and repair. When the problem raised its' ugly head, I conducted some in water trouble shooting that resulted in my conclusion that the heads were screwed up. I am capable of repairing the heads in the boat.
While running the engine I got a low oil press warning. I trouble shot this by attaching a mechanical oil pressure gauge and turned the motor over with out plugs in it and did not get any oil pressure. I am afraid the oil pump might have packed it in. The dash gauge indicated zero also throughout. I tested the sender and it seemed functional. If the pump is bad I want to pull the motor out of the boat while in the water.
1. Have I accurately determined the oil pump is shot?
2. Could a bad lifter cause low oil pressure indications?
3. By disconnecting the drive shaft and sliding it aft, will I have enough clearance to pull the engine and tranny up and out? I think it will hit rudder before enough clearance is achieved.
4. If no to 3.can I remove just the motor.?

Any advise would be greatly appreciated.

Can't help with one and two.

If the 310 is anything like the 330, It's tight, but number 3 is doable. You will probably have to remove the engine hatch from the boat to get the maneuver room.

Number 4 would be mental suicide IMO.

Chances are slim your pump is toast. 2 steel gears rotating in a steel housing. More likely would be the valves in the oil filter housing or the filter itself. Or the sleeve that connects the dizzy to the oil pump broke. A lifter could cause low oil pressure if it popped out of its bore.

Thanks for the feedback.

thank-you. I will check those points.I have heard that sometimes the pick-up in the oil pan falls out of its' housing.

I have replaced my engine and am in the process of replacing the other. You will need to pull the prop to allow the shaft to slide back thru the transmission. The coupler is the hard part, one came off just fine with a gear puller and the other engine I am having to cut it off. You will need to remove all exhaust and manifolds to remove the engine and transmission as one. Go ahead and change your shaft seal while you are at it. You will have the clearance to remove engine and transmission as one unit. Just go very slow when lifting.

Thanks for the info jetpartner.

I would pull the dist, install a priming device, and install a mechanical gauge. A low oil warning can be caused by a hot engine, running low on oil or a serious leak.
Did you discover why water was in the cylinders? blown had gasket? Those usually come from a serious overheat condition. If the pump did go out you would have heard pushrods and rods knocking and clacking.

BT ,Thanks for the input. I am assuming I got water damage due to reversion. I will know for sure after heads are off. The engine did not overheat. Head gasket could be the problem. The engine was doing a lot of clacking at the time the oil pressure indicated bad,so I am assuming the pump might have gone.This water issue happened before and I re-did the heads. 100 hrs later this problem occurred. At this point I am going to remove the motor and re-build//replace as necessary. I am tired of bending over in the bilge and trying to fix. Will be easier to bring home the motor and fix in the garage.
