Hoping for some help and suggestions [to use a Morse MT3 with existing Evinrude Trim and Tilt remote cables]. I had the Montauk out last weekend and, throughout the day, slowly developed problems. The first with the idle speed progressively getting faster, and finally the inability to shift into neutral. Yes, made for an adventurous trip back to the dock. I've narrowed the cause to a few different areas: remote contol box, control cables binding, throttle and shift sticking at the engine connection, or a problem with the engine gears themselves. Starting backwards: no problem at the engine connection and not able to find the cables binding. Even with the engine down and not running, shifting in and out of gear and advancing the throttle is very stiff. I [plan] to replace the old controls and potentially the control and throttle cables, but am unable to find a suitable and same vintage OMC control with tilt and trim. I'm leaning towards a Morse MT3. Will I need any adapter for the cable ends [of the existing cables to connect to an MT3]? Or, does the Morse MT3 use the same attachments? I'm going to need to add a tilt-trim switch, which I'm planning to mount to the dash. Is there one that you can recommend? I would prefer not to buy a large pannel and am thinking more of a three-way switch that would have up, down and off. Thanks for the help. Mike

Mike--You could just wire the trim to a small momentary [single-pole double-throw center-off] switch. That is what I ended up doing when my nearly new BRP dash mount trim switch failed. |

Thanks Jeff. Is there any particular model and brand? Or, no special magic?Also: notice I have a three-way rocker that's not currently being used and might be a good option, as well. |

Your local marine chandlery should have a suitable switch on hand. Specifying electrical toggle switches can be astonishingly complicated. Rather than dig through a 1,800-page catalogue, just get one at the boat store. |

Before investing in a new top-mount remote throttle and shift control, you might consider disassembling the existing one and taking a close look at what has been going on. Quite a few years ago I tore down my Mercury remote controls. I found all the grease had dried up, there was plenty of metal shavings and residue in the works, and a general lack of lubrication. I used a fine file and some emery cloth to smooth the abrasions in the cams, lubricated all the pivots and metal-to-metal surfaces, and generally cleaned up the mechanics of the assembly. It returned to like-new working order. In terms of a mechanical assembly, these controls are rather crude. They're not exactly like trying to repair a Swiss watch. It also seem common that old mechanical cables cause problems. You should look carefully at them. Maybe they are the cause of more of the problem than you think. Also, it would not make sense to me to invest in a new and expensive remote throttle and shift control, either an MT-3 or something else, but retain ancient cables to use with it. If you are going to spend money on a new MT-3 or other new controls, get new cables, too. And the newer cables are generally better than vintage ones, being smoother and with less stretch, but more flexible. What vintage OMC controls are you looking for? I have a very nice single handle Evinrude c.1992 control in excellent condition. |

I have owned the boat for 7 years and replaced the control cables early on in the "restoration". They have worked without issue until this recent problem.The OMC control box that I have has been taken apart many times for various reasons. The red wire for the tilt/trim had been chaffing against the nut that holds the contrl arm to the box and the was has sinse been spliced. No further issues with the tilt or trim but getting the nut seated again with the right amount of pressure has been an ongoing issue. If it's cinched too tight it's difficult to advance the throttle either forward or backwards and too loose and it's flopping around. It has a tendency to loosen over time and with vibration. The black plastic cover that runs the length of the cotrol arm requires a wrap or two of tape to keep it on. So you get the idea. The outboard is a 1987 Evinrude 90 and the control is a top mount, single lever w tilt and trim. It's silver in color - maybe chrome? and without a keyswitch. Jim - if you have one that will work I might be interested. Thanks Mike |
