Re: Oil pump

Difficult question to answer. Are you pre-mixing your gas or using the oil injection system?

If you're pre-mixing and this is the way you got the engine then the prior owner may have removed the oil pump driven gear. In that scenario then the adapter in your picture would not turn. It should have been removed and a proper block off system installed.

If you are the original owner and you're still using the oil injection system without any modifications then, yes, this adapter/bushing should be turning.

If the later is the scenario then pull all the plug wires, remove the adapter and you'll see a steel gear shaft. Turn the engine over by hand while holding the shaft center of the hole. If it turns, replace the oil pump and adapter and you should be o.k. Make sure you test the oil pump output after replacement.

If it does not turn, you need to rebuild the engine. It has been run without oil and the driving gear on the crankshaft has failed. Pieces of that gear have gone through #2 cylinder and may have caused damage or will if you just replace the gear and don't get all the pieces of the bad gear out. The engine has also been run without adequate lubricant and has likely scuffed pistons. Those will fail to seal correctly in short order so you'll want to at least hone the cylinders and replace those pistons.

In otherwords, best case you just need to do the job correctly. Worst case, you need to rebuild the motor.

I'm hoping for the best case..

Re: Oil pump

Crap. This ant good. I just bought the boat and dont know anything about the motor. It runs good on the hose and has good compression but from the other post i posted im trying to find a beeep beep beep problem. I would like to just do a premix and be done with it but dont know how. Even when i unplug all the wires i still get the beeps. Ok looking at the back of the motor where will the 2 cylender b so i can pull the plug and look at the piston

Also how do i get to the gear u are talking about so i can see if its still there and intact. Does that lil piece with the indentation pop out or what

Re: Oil pump

You can remove the rotating bearing using a small wood screw. Thread it in to the slot just enough to catch and pull the rotating bearing out.

Go to www.marinesolutionswi.com for other instructions on checking out the oil injection system. You should be able to see the stripped plastic gear around the crankshaft when you remove the rotating bearing and steel driven gear.

Marine Solutions also sells a very reliable Electronic Oil Injection system if you want to retain the convenience and lower pollution of the original system.

Re: Oil pump

Ok will do. So when u say a small screw. Are u saying to screw it in to the slot where the other part goes in to

If it aint turning then that's why you're rotational sensor is going off. Be an optimist... you found the source of your beeping alarm finally.. Just trying to cheer you up... you're right, it aint good.

#2 will be on the upper left looking forward from the back of the engine. There's also a 2 cast into the block at that point.

Wait, this is still the V6 isn't it?

Re: Oil pump

Yelp still a 1992 150 But if i unplugged the sensor shouldnt it stop beeping. Ok im going to look at the gear tonite and see what is going on. So is there any hope for the motor even if the gear is broken. With out pulling the powerhead.

If the gear is intact what do i need to do next

The relatively small owner's manual has instructions for what to do when the oil alert alarm goes off. If you don't do them, you will probably ruin the engine. If you have run the engine without oil added to the fuel while the alarm was going off, you have seriously damaged it.

The alert module compares pulses coming from the ignition to pulses coming from the rotational sensor. If both trains are missing, the engine is stopped, no alarm. If EITHER train is missing, the alarm goes off. If the sensor is hooked up and the pump isn't turning, the pulses are missing. If you disconnect the wires, >>>____________________ (fill in the blank.)

Re: Oil pump

Ok so how would u do a oil block off and still have the alarm for the over heating. I thought they were both on the same line or at least worked togather

Re: Oil pump

Ok guys i found the problem. No compression on # 2. Just like yall said What a junk of an ideal way to do a motor oli system. Well now what. How much should this cost me to fix. This sucks

Actually, the oil systems is a pretty good one but when it fails, the alarm is too late to save the bacon.

Your best solution is to tear it down and rebuild or look for another powerhead. The cost will be about the same if you do it right but you can econo build it and get by for less. Depends on the tools you have and your experience building engines.

........Especially if you ignore it.

The output of the oil alert and the overtemp switch are wire or'd together. Either one works independent of the other. You can completely remove the oil alert module without losing the overheat alarm.

Re: Oil pump

Thanks guys. The local shop said for him to fix the one cylinder and the oiler about 1700 to 1800. About 3000 + labor to do a power head with warrenty. What should i do. All the other holes have 110 psi well the one on top right (1) has 95 psi. Should i do a whole rebuild or one possable two hole rebuild or look for a power head. Im going to pull the head on #2 and look at the cylinder walls. Can these be honed or does this have to go to a bore shop

The first thing you need to do is make a logical decision and try to avoid the emotional aspect.

If you have the money to spend on a powerhead rebuild the price you are being quoted is respectable.

The option of boring one hole, cleaning the rest up and putting it back together is viable but when you compare a repaired engine to a virtually new engine with a full rebuild the cost is not effective.

You didn't say what you paid for your engine. Buying another engine will feel like a crap shoot to you and parting out your current engine to recoup the loss is a lot of work.

Still, a newer engine in great condition can be had reasonably if you can shop it locally. The drawback is that you would have a virtually new engine with a total rebuild whereas any motor you find is going to be in used condition and will need a rebuild sooner than your motor with a fresh rebuild.

Confusing and difficult decisions, I know.

How would I go? I would have my mechanic evaluate all the components of the motor, including the lower/unit and then, if that was all good I would proceed with the full rebuild.

If the evaluation was not good, I would part the motor out and have him look for another motor for me. Odds are he knows someone that he might be able to swoon into a new motor if they could get a decent trade in value for their current motor. Your his bank on this so he has the incetinve to work harder to get a deal done.

If you work the angles you might be able to turn this misfortune into an opportunity.

thanks. you my friend have been a huge help. I will look over my opt and decide what i can afford to do. I bought the boat as a resale but after working on it and seeing how nice it turned i was going to keep it. We just had a baby and it would be great boat for a family rig. I have a blazer w/250 yammy for fishing but wanted a boat that we could all go out on. I gave very little for the boat but didnt want to put alot in it Now i have to decide what way i want to go. Is there anywhere where i can get after market parts for this motor. I looked on line and saw that just the one piston was 150 ish. Anything out there wheee i could save some money. Also i couldnt find the oil pump gear that melted down on any of the links i looked. Where is it located in the parts fisch and what is the proper name. Thanks agaim for all the help and advice.

Send a PM to Fatzbullet - He can give you some advice about which parts you need. You might find many of them right here in the iBoats store. GLM makes some inexpensive pistons. I'm running a set in my fishing motor and haven't had any problems. The iBoats store had them at one time for some applications.

For those times when you can't find it in the iBoats store, www.promarineusa.com has just about everything you would ever want. You do need to download the catalog and then go back to the website and search for the part nr to get pricing. Their prices are list so I usually go through someone with an account for better pricing.

I hope that helps.
