[deves3000gt]

ok my newest problem. is i have a mercuiser outdrive when i hit the trim button the pump kickes on but nothing happens if i go up i hear the pump strain a bit but when i try to put the drive down the pump spins fast has a second or two that sounds like it is puping then it changes pich again nothing happens ether witch way

i dont know if this helps or is even related but the power strearing fluid is full, but i dont think that they are conected right?

ok and while i have you here i am trying to start the motor...been sitting for some time. i just finished putting the starter in thankyou for the info. i got it to "putt" once or twice but no go. now i took the air filter off and while i was cranking over the motor i saw gas coming up from a small tube in the middle of the carb...normale?? it is a chevy 350 with a 4 barrale carb.

sorry this is so long

i have a mercuiser outdrive

Come on, you can do better than that. This don't tell anyone the year, type or anything else.

That's like me saying I have a Chevy pickup truck and it doesn't shift right, anyone know why?

Re: help with my newst problems

Ok, 99% chance you have air in the system. No the ps system and the power trim are not related. If you have hydraulic trim tabs then you have a 3rd system.

If you have air, you very likely have one of two things worn out:

1) Climb outside the boat, and around the back. At the bottom of the transom fitting you a 'distribution block'. there are 4 hydraulic lies going from this block to the triim cyliners. They were the culprit on my boat...they wear out

2) If you are sure it's not 1), then take your boat to a dealer and have them pressure test you cylinders. There are o rings which can allow air to enter.

If you do have air in the system then you may also have water in the system. Locste you pump (Follow the sound). It will look like a cylinder (The motor) coming out of a rectangular base (Resvoir).

Check your levels as described in the manual for your boat (Go into the adults only section in the main page of this forum and download the applicable manual for your drive). This means unscrewing a cap screw and using a dipstick of some type....bet your way low. See if the oil is milky whiteish...if it is you have water and should flush the system.

There is a chance that one of the check valves in the pump body is leaking by, but I've found these to be very good units over the years, and the vast majority of problems have to do with leaks.

Good luck,

Chay

ok so i will look at the levels in the morning. the lines out side the boat look in good cond. maybe even replaced, they look very clean.

i waas able to get #'s off the block if anyone can tell me whatever they can about the motor the #'s are 4909168

Re: help with my newst problems

It's too old to ID with a SN, so you might want to take some pictures of the drive and engine. Is there a transmission behind the engine?

Re: help with my newst problems

ok i'l take pic in the morning. does it make sense that the tag i got those #'s from said mercrury on it but the valve cover has what looks like the corvett emblem.

about my carb. ?'s i will try to get a pic of it also but off hand there is a tube in the middle of the carb that was letting gas come up and spill over down into the carb i dont think that is right but the only carbed motor i have worked on are bikes....not the same

Re: help with my newst problems

It's over 30 years old, what makes you think any of it is original.
Read this forum for a while, there are people putting anything that runs in a boat, doesn't matter if it's right or wrong. Safe or not.

Re: help with my newst problems

It sounds as though you are describing the carb 'flooding'.

Without proper ID it is going to be very difficult to order the correct carb kit.

Does your trim pump have any hoses connected to the shift linkage?

Re: help with my newst problems

The hose/tube that is spilling raw fuel into the throat of the carb is supposed to do that when the fuel pump diaphragm is broken. (If I understand the description correctly) There should be no fuel in that tube. It's purpose is to flow that fuel into the carb rather than into the bilge...BOOM. If that is the case, you really need to research just what you have there. If that is an automotive carb, corvette on the valve covers, etc, check the alt and starter they have to be marine grade. Kinda sounds like a cobbled up hazard....be careful with fuel and a closed bilge.....

it is flooding looked at it this morning with no throttle gas pumps up and out this tube. I think the float is stuck.

I dont think the trim pump has any hoses to the shift linkage. in looking sloser to the pump i did notice one of the hydrolic lines was wet and was most likly leaking...now how to fill the reservoir. didnt have to much time this morning befor work but i didnt see any fill cap. does the motor have to come off or do i just need to open my eyes.

Re: help with my newst problems

If your hyd pump is a black square plastic 'box' with the motor right on top, then the fill plug is a slotted screw found on the top corner of the tank, recessed about a half inch lower than the very top.

Fill the tank with the outdrive fully down.

The old style restaurant catsup/mustard squeeze bottles with a pointy tip work great.
