Universal 5432 Throttle Set Up

I have a 1980 Mariner 36 with a Universal 5432 engine. It has one lever for the throttle and one lever for the transmission. Iím getting used to it, but sometimes when Iím docking it can be a problem! Also, the engine kill set up by pulling the throttle back is not great. I have some stiff springs installed on the throttle linkage, but the idle is never the same when I pull the lever back. Iím thinking about install the single lever setup from Edison but I canít figure out how to kill the engine. Has anyone made this change or figured out a better way to control the idle? Thanks for your help. Please call me at my office @ 800 811-2009, if you want to discuss your ideas.

Re: Universal 5432 Throttle Set Up

Had that arrangement on my previous boat with a Universal 5411. My current boat has a Yanmar, which has two levers on the pedestal plus a pull stop control on the engine panel. You would have to rig something like that up if you went with a single lever control. Just look for how the stop control is pulled on the injection pump. I prefer the two lever control and would suggest seeing if you can adjust things to make it work better..

Re: Universal 5432 Throttle Set Up

Jim,

Thanks for the reply. I can live with the 2 levers. But I have no way to shut down the engine. It's not a seperate unit. You shut the engine down by pulling back the throttle. Not good, you kill the engine if you pull it back too far!! It's contected to the same swing arm as the throttle. I would install a pull cable but I don't know where to connect it to kill the engine. Any ideas would be appreciated.

Re: Universal 5432 Throttle Set Up

I have the Universal 5424 and the spring is strong enough that there is no chance of stopping the engine accidentally. I think your problem might be that the mechanism is stiff and in need of lubrication - that's why it doesn't go back to the right idle every time, and why you can't feel when you're pushing against the spring.

After buying the boat, the first time I went there alone I started the engine. Then I couldn't figure out how to stop it! Had to phone the broker and ask them.

Interestingly, somehow my throttle is reversed - forward is idle. How can this happen?

Re: Universal 5432 Throttle Set Up

I have the same problem on my S2 11.0a. There is no spring anywhere and I'm trying to find a way to install one. Mark, where is your spring located? Is there any way to post a picture of it?
Thanks,
Howard

Re: Universal 5432 Throttle Set Up

Thanks for that link. I had seen the schematic for my engine, but not all of them. It looks like the only engines that had the spring were the M-12, M4-30, and M3-20. All the other models look like they had the same speed plate or pretty close. But Mark said his 5424 had a spring - and the schematic doesn't show it. Hmmm.
But at least now I can see how the spring is set up on those other models. I'll have to take another look at mine and see if there's any way to rig something now that I have an idea how they did it.
Thanks.

Re: Universal 5432 Throttle Set Up

This is interesting. I'd like to see your set up as I haven't used one before. My Gulf 32 has the 5432 but a standard arrangement with one lever transmission and one lever fuel on the pedestal. The engine kill switch is entirely separate and in my case is down in the cabin area near the electrical panel. Idle is set by a screw on the throttle on the engine. Really straightforward.

Because I have the same engine and my system is comparable to what I have seen on the many other boats I have chartered and crewed aboard, I am really interested in how yours is different and what you are trying to do.

Re: Universal 5432 Throttle Set Up

I won't be near the boat until Saturday but I could try and take a picture of the mechanism then.

Re: Universal 5432 Throttle Set Up

I'm not sure I'll need a pic now that I've seen the schematic.
As for my setup, I'm sure it's very similar to Mariner36's - there's an up/down lever on the port side of the binnacle for the transmission and a fwd/back lever on the stbd side for the throttle. To kill the engine, you cut off the fuel by pulling all the way back on the throttle. The problem is that when maneuvering in close quarters, it's too easy to kill the engine. And if you have to goose it, it's hard to get back to the ideal idle speed - there's no spring, no detent, or even a screwdriver adjust. I do have a little gizmo to adjust the friction of the cable, but it doesn't help when trying to set a repeatable idle speed.
Before I got this boat, I always killed the engine by pulling a knob near the instrument panel or down below near the engine. I've only seen one boat where you killed the diesel by simply turning off the key.
I can see a way of rigging up an adjustable stop, but then I don't know how I'd kill the engine. Maybe a little valve in the fuel line? (BTW, I have a mechanical fuel pump, not electric. I'm thinking about an electric.) I thought of cutting off the air, but I understand that's a big no-no with a diesel. So now I'm interested in your setup, Brian. Since you have the same engine, I'm curious as to how your kill switch works - is it really a switch or a pull knob? If it's a pull knob, how does it hook into the throttle mechanism?
Thanks,
- Howard
