That center hole is where I need to put it. I plan on doing that tomorrow night if I have time.

Should the oil in the big hoses that go to the bottom of the engine and then back to the oil tank move? I don't see any "pumping device" and the oil level stays the same as the tank level in the return lines.

Ok, thanks. That's what I thought. I marked the lines and the oil gauge in the compartment and both dropped the same. Still learning here guys!

No boating for me this weekend. Saturday on the yard and today was spent at the Texan's game. It rained all day too. I did pick up some tools for the boat and some paint to spruce up the engines. I did lock tite every single bolt that was on the exhaust system for both engines.
I plan on taping off the engines to do the painting.
One thing that has puzzled me is why the boat had premix in the fuel tank. I think I covered this in a previous post.
Both engines have had work done to them. Port engine has brand new gaskets at the bottom of the cylinders. Starboard engine was replaced in 2011.
I have bled the oil lines to the pumps and from the pump to the block squirters. There is definitely oil coming from the tubes and after 3 full tanks of running premix gas thru the engines, my oil is getting low in the tank. This thing smokes like a freight train at idle and just off idle.
Would the concensus be that the oil pump is working correctly and I can stop with the premix? I have the oil pump properly adjusted and bled out all oil lines. I have also visually checked oil flow at idle and actuator at full and verified oil flow.
What do you guys think?

Control cables are perfect and the lines are also new. Actually all the lines are new. I know the smoke is coming from the pre mix and the automatic oilers both working together. I was thinking the previous owner did the top end on the port side engine and was going to break it in with the premix. I didn't get a lot of information on the boat from the previous owner. Kinda going on a hunch here.
I have run approximately 45 gallons of pre mix thru the boat, and compression remains in the 150ish range. I would think I'm good to go. I am going to fill it up and let the oilers do their job.
Thanks guys!

Just checking in. Had the boat out a few times this year and still working like a charm.

Had it out this weekend and pulled into the water side bar to check out the band playing. When I came back out, to my surprise, the boat was sinking. I had water up to the bottom of the seats. I immediately jumped in and turned the pump on and then jumped in the water and felt for the plugs. One is the screw in type and the other is the expansion style, or it was. Must have come out on the ride there.
Well, it just so happens that the float on the dess key fits perfectly in that hole! Saved the day. The water was up over the carbs, so I pulled the plugs while the water was draining and cranked the engines till all the water was out of the engines. Put new plugs in and fired up both engines and let them idle till all the water was out.
We idled through the inlet to the lake and the engines were performing perfectly. I decided to check the makeshift plug and it was still solid. We finished the day with some tubing and wake jumping.
These engines are amazing.
I ordered a screw it plug. That's not going to happen again.

Update to my money pit.
After a couple more times out last season, I lost the port side engine. It locked up solid at the crank. I fogged the engines and flushed clean water as always. Both engines have had top end work by evidence of jug gaskets. The very end crank bearing locked up. Looked rusty when i took it apart. I had a spare engine and dropped it in to finish the season. That was a couple of trips.
Fast forward to February. Went to start starboard side, and it was locked up. Pull the pump, no issues with it. I rebuilt both at the end of the season. Still couldn't turn engine over. Put some oil in the plug holes, hoped for the best for a couple of days, still no joy.
Pulled the engine, jugs, and guess what, same bearing was rusted as on the port side.
I realize that fogging after use is important, but I wonder if it's my method, or if it was just time for them to fail.
Both engines are original, well, they were before my transplant. Both engines had the same newer jug gaskets. Can't say if any crank work was done.
If you have read this whole thread, you can see the boat was a disaster when I got it.
When i fog an engine, it is the last thing I do. I back flush the engine with fresh water first, then run engine dry for 2 minutes to blow out flush water, then at the end of the 2 minutes, I hit it with the fogging oil several times till it dies. Then, I pull the plugs and spray the cylinders.
This is my standard method after every outing.
Any suggestions, or we're the engines just overdue?
Just to clarify, the bearing that failed on both engines was pto side. The last bearing by the seal.

Unless the engine bearing took damage when the engine bay flooded or when you flushed it last when fogging and water got in the engine. I usually just fog the engine and turn it over with out starting it at the end of the season. Its hard to know on a 1994 since you have no hour gauge to go by. If they did just a topend and it had a ton of hours that is what usually happens the bottom end gives out. Boat looks good send that engine out or if you can find a cheap ski to get a donor engine to keep you going.

I think that they had some hours on them. But, then again, both engines did take on water, hard call. Both engines died within a week of each other. One at the end of last season and one this month. The one this month did sit since September in the boat. But it was stored in the state mentioned above.

Newly rebuilt engines and then, freaking wear ring blows out today! Just can't win. Well, local guy had a blue ebay ring, and it dropped right in. Both engines are broke in and ready to hit the lake tomorrow for fireworks.

Replied mike. Spent the evening out on Galveston bay in Kemah watching the fireworks. Very awesome night.
The race back to the docks was more exciting. 5000boats all headed to the no wake channel, in the dark. Most of them overloaded with people. My speedster took the lead, but, being a no wake zone, cops were all over. They didn't seem to care, I was quickly passed and had to ride a wake for a bit.
Driving in the dark was a new experience for me. Can't say I liked it much. I can say the boat is performing perfectly

Hey just saw your thread. Originally from Houston and went to school in Galveston and we live in Charleston, SC now. I've got a 96 Speedster i'm restoring and needs a new port engine. Your 94 looks great! Maybe ill drag the boat down this Christmas to ride if its as warm as it was last year haha.

I know this is a older thread I am just hoping that you are still active I am considering doing this rewire to my speedster (same year) just got it and the diode is broken in mine as well and new (used) mpem's for a 94 are expensive because I guess they are hard to come by... I am just wondering when you did the rewire did your key still work or did you have to get it reprogrammed? I ask because when I was calling around trying to find a new mpem I was told that I would have to bring it into a dealer to have the new mpem reprogrammed for my key?
