1976 Silverline Camaro 17T tilt issues

[skswiger]

I recently acquired my grandfathers boat, 1976 Silverline Camaro 17T. The OMC 140HP engine is in good running order, however when I try to tilt the drive to change fluids, the solenoid clicks. Any suggestions?

The first thing I would do is to check all the ground connections. Also pull the big fuse plugs apart (there may be two of them) and clean all the terminals and stuff some dielectric grease in the female sides. I do not know which fuse plug is the one for the tilt.

Other than that, you could have an issue with the tilt motor. And as I am thinking about it, check the 30wt oil in the tilt gear box. These are notoriously famous for filling up with water, leaking in thru the tilt shaft seal. This can effect the tilt. When you put the cover back on the tilt box, it should be double gasketed.

I will try that. I also manually dropped the drive down. Oily fluid came out of the water intake. ??

Welcome aboard skswiger: - you have a Comoro, not a Camaro (ask me how I know ). Buncha' stuff on it HERE for you to look over (as far as the hull).

Did the oil come out the water intake or the exhaust? (on a '76 the exhaust should be the triangle-ish tab at the back of the cavitation plate over the prop, and the water intake is on the front of that same fixture - metal screens).

What do you mean by fuse plug? New solenoids did not take care of it. I have checked every ground I can find. A volt meter shows 12 in and out of the first solenoid, and 12 in the second, but nothing out of the second. The oil came out of the round hole not the triangle exhaust.

You are not being clear on your descriptions. Those solenoids have two sets of terminals. One set is the switched power from the tilt toggle and a ground. The other set is the primary power transfer. One is power IN and it is always live and the other is the power OUT. It is only live when the solenoid is energized by the smaller terminals from the tilt toggle switch. This is where the fuse/connector plugs come in. They are the plugs that connect power from the helm to the wiring for the engine and outdrive. They are multi pin connectors and can corrode with age. You need to determine if juice is getting thru to the energizer terminal on the solenoid in question. The Up solenoid will have one pin and the down solenoid with be on another pin.

Does the second solenoid click when you toggle the switch? If it does but does not transfer voltage to the output lug, then it is defective. That of course is assuming that it is the right solenoid. If it does not click when you toggle the tilt switch then everything I mentioned previously still applies.

As far as the oil, you have to be more specific about where this 'round hole' is.

The round hole has a mesh screen like you said the water intake has. It's just in front of the exhaust.

skswiger can you post a picture(s) of that Comoro? Been a long long time but I think I remember one my Grandpa and I built a 455 Olds in with my grandpa in between beers. (Scotch for him, he was a classy bastid) I seem to think it was a '74. 18 footer too. Ran it on Riverbend by Harrys restaurant and I can tell you there is a remarkable amount of G forces when the throttle is hammered down in a 455 jetdrive boat that small.

That sounds like the water intake ... I think it was located there on older drives (mine's a '72 and it's on the tab) - like early 70's or even late 60's.

My guess is that you've got gear lube leaking down from your upper gear case. But, it's gonna' be hard to tell without taking the drive off and apart (not disassembling, just pulling it apart like you'd be servicing it).

Re: 1976 Silverline Camaro 17T tilt issues

I've tested the tilt motor and it's bad. The parts lists I've found for this boat indicate the tilt motor and trim motor are the same part numbers but they look different. Any advice?

 

[southkogs]

Re: 1976 Silverline Camaro 17T tilt issues

I don't think those are the same motors. Not looking HERE, anyway. Though, I think your tilt motor is still available through them.

What I did was had mine rebuilt at the local auto parts shop. They'd rewind starters, alternators, etc. Cost me around $50.

Thank you very much.

Re: 1976 Silverline Camaro 17T tilt issues

Well I just don't know. I've checked wiring, replaced solenoids, and tried a new tilt motor. Nothing works. I guess now I need to just go through every bit of wiring and see if I can find any grounding issues. Any ideas?

 

[southkogs]

Re: 1976 Silverline Camaro 17T tilt issues

Has it worked at all since you've had it? Solenoids were clickin', right?

Can you lift the stern drive up and down with no problem? I mean it moves freely on the trunions, correct?

If so, support it up (you may have to remove the quadrant gear) and then hit the tilt and see if anything moves. You could be having a problem with the clutch pack or worm gear.

Re: 1976 Silverline Camaro 17T tilt issues

It worked two years ago when it was parked Solenoids do click. The drive moves up and down freely, when down it still clicks. It clicks when the tilt motor is uninstalled as well so the power is not getting to it correctly is my guess.

Re: 1976 Silverline Camaro 17T tilt issues

So ... when the motor is not connected to the hammer coupler, does it turn when you energize it? Solenoids are pretty cheap and easy, but I'd test further first. Maybe hit the motor leads with a meter?

 

[skswiger]

Re: 1976 Silverline Camaro 17T tilt issues

The motor does not turn when it's energized. I replaced the two solenoids all ready and that did nothing. That leads me to think it's got to be a grounding issue.

Sk, it could be a grounding issue. A weak ground could allow 12 volts to pass until a load is put on it. Then insufficient current is allowed to flow, to power the device. If you have the motor connected but do not have it installed, the motor would require minimum amperage to operate. I take it you are saying that the motor does not even turn in this state?

In that case, something else is amiss. You have new solenoids (hopefully the right ones). You just need to test the voltage at the output sides of the solenoids. I believe that those are chassis grounded solenoids so having removed and replaced them, their grounding should be good.

There is always the possibility that the motor is toast.

Re: 1976 Silverline Camaro 17T tilt issues

I tried with a new motor. The solenoids were for my OMC by part #. I tested the voltage on the output of the solenoids to the motor plug and got 12.5 volts. I'm going to go through the wiring in it's entirety this weekend and hope to find a missing or cut ground. Thanks for all the help.

Re: 1976 Silverline Camaro 17T tilt issues

I had the exact same problem on my 17t last year. the tilt motor does not have a ground wire on mine. it relies on the mounting bolts to the housing for ground. I loosened the bolts a few turns and tightened them back down and the motor worked after that. I am considering adding an additional ground strap to mine.
