Marine Trader Steering

I am a new owner of a 1977 Marine Trader 40. Yesterday I made a hard turn to starboard and something has broken as there is no steering at all now. I used the Raymarine autopilot to get it back into the slip with no damage.

The boat is mechanical steering. I have traced the problem to the rearward outboard steering shaft. The input sprocket is turning the shaft but there is no motion at the aft end of the shaft. *There is no noise when rotating the steering. *Is this shaft a solid piece or a 2 piece that is cross bolted in some inaccessible place? *Has anyone else done a repair on this type of steering in these boats? *It appears I have to take out the cabinetry in the aft cabin and saw a hole thruogh the floor for any access.

I'm planning to go over to the marina after lunch with sawzall and measuring tape in hand.

Any ideas appreciated. Boat must be fixed this week to move to a new marina next weekend..... else I will be paying for 2 expensive slips.

*

Cheers

Pappy Chris

Congrats on your new vessel! I have a Taiwan Sundeck with hydraulic steering and to access the top of my rudders on the Port side I can pull a lower drawer from the cabinet on that side. For better access someone in the past cut a very clean rectangular panel from beneath a stool storage area. To refasten the panel he attached a 1" "picture frame" onto the panel and used SS screws th hold the "frame" onto the cabinet. It is a pretty good way to address the problem IMO. Starboard side is accessed beneath the aft bed.

* I have a 77 40' sedan, there is a joint in my steering shaft in the engine room aft end. I suspect there is one in yours there also. It is a simple through bolt and is subject to wear. Congrats on your new boat & enjoy.

RE: Marine Trader Steering

We just got back from looking over the steering situation on Moonshine.
The steering shaft rusted through and broke off just before the pillow block
bearing located behind the starboard drawer section in the aft cabin. The shaft
was severely rusted due to years if water leakage.
I went forward into the aft head and took out the compartment in the shower and
cut the shaft off in a solid non rusted area. I then got behind the drawer
section and cut the shaft 8" behind the pillow block bearing. All I will have to
do is section in a 60" piece of galvanized tube and refit the pillow block to
the hull side and its fixed. I know there is a spray on cold galvanizing paint
that we used to use in manufacturing railroad parts that works well. I will coat
everything with this paint when the job is complete.
The quadrant and cables are all in good shape but I believe I will replace them*next year with a heavier stainless cable and new buckles.

Buying a used boat of this age is a process of learning how it's built and
discovering what has been neglected due to out of sight-out of mind. I have
learned that boats don't break stuff unless you use them and you (the new owner)*don't find out until it breaks.

I will post pictures (had my photographer wife along) as soon as they approve
them.

* My m/t has a section with a turn buckle located above the lower helm and another below the lower helm.

RE: Marine Trader Steering

I found that every piece of chain has a turnbuckle in it. My first trip across Corpus Christi Bay I lost the upper helm because the jamb nuts we not tight. *The buckle backed off and the chain began slipping around the bottom sprocket. *

It's now a problem I will never have twice.

RE: Marine Trader Steering

Hi

Look for a turnbuckle like you'd find on sailboat rigging. *If you don't have them I'd suggest them. *It's much easier than taking out a link... IMO.

Just have to be careful that you don't over tighten.


Cheers

RE: Marine Trader Steering

Not a Whole lot to tell. It's a single engine 120HP Ford /Lehman. *My first single engine of this type so docking is a bit amusing for some to watch. We are currently docked at Corpus Christi City Marina but are moving to the north side of the bay so that Moonshine is only 5 minutes from our house here in Aransas Pass TX. I was introduced to the world of trawlers about 5 years ago. Moonshine came up for sale last year but was way out of budget at the time due to moving and buying a house. We moved here from the Kansas City area last year. We are also sailboaters. I sold one of my sailboats this past August which enabled us to buy Moonshine when it came up for sale again. *Circumstances of the sale enabled up to pay cash for it this time.*

In the 2 months that we have owned Moonshine I have rebuilt the Velvet Drive (twice due to a bad snap ring), repaired the rudder post packing, replace the house water pump, changed oil and all filters, replaced zincs, replaced strainers and started sanding and coating the railings.

Recently picked up a complete 16K BTU A/C unit with a bad compressor for $40. Going to fix and install that to aid in cooling the V berth and supplement the salon. *It gets really warm here in summer. We've bought some white shade cloth and are in process of making snap on covers for every window in it.*

There are lots of things on the agenda for upgrade and improvement over the next year or two. We expect to only upgrade one more time to a 49-50' Marine Trader for our retirement.

Of course in my world, retirement will only come when I am to tired to shovel the dirt back out of my hole in the ground.

I guess this is a start. ~~~~ Cheers -- *Pappy Chris

Next time I am over on Moonshine with a camera I will get you pictures. Every chain has a turnbuckle to adjust it.

Moonshine has eye-eye turnbuckles. They've used a pin thru the side plates on the chain to connect them. *The pins are wired. The buckles use jamb nuts on the ends. *A trick I used from my dune buggy racing days is to put a dab of silicone on the nuts to keep them from losening.

When I lost my upper helm I found that someone had not had the jamb nut tight and one was not even there.

Have never noticed a turnbuckle in the system, and can't imagine how one would work with a chain other than to move the sprocket location, but I will be under there today. If there is one, I will find it. Thanks for the heads up. Taking a link out of the chain is quick and easy, but that is why I love to ask questions on the Forum. Thanks to all!

The turnbuckles on my MT 34 are accessible through the electrical cabinet.

Marine Trader Steering

Since I could not buy what I needed I spent 2 hours and $50 manufacturing what I needed. *It's to be installed tomorrow.*

This has been such a frustrating week trying to find a part that would work.

RE: Marine Trader Steering

grrr --2nd try

*

We moved Moonshine the 20 miles across the bay yesterday to her new slip. I had nary one issue with steering or transmission. We arrived in 2 1/2 hours, dock to dock.

The pillow block bearing should arrive today (from Grainger) to complete the steering repair. I will have to glass in a new mounting for it.

Having Moonshine only 5 minutes from the house will make it so much more handy to take care of projects now.

Cheers

RE: Marine Trader Steering

I built a new and improved steering shaft splice that has much better clamping power. Aslo replaced the pillow block bearing while I was in there. Works smooth as original.

RE: Marine Trader Steering

In addition to the steering I've had to deal with exhaust issues too. Found a rust bubble in the side of my engine's exhaust elbow while RnR the heat exchanger for cleaning. One thing leading to another I found the POs had rigged a series of adapters from 3.5" down to 2.875" and then back up to 3.5". So now I have all new exhaust parts of 3.5" size including the lift muffler. All new elbows and clamps to go with it. *Yesterday found a brittle fuel return hose. So next project is all new fuel system hoses.*

Just a process of rebuilding reliability back into her. PO's either jury rigged stuff or took the "don't fix it if it aint broke" approach. Feeling better now that I have had my hands on all of her systems myself. *One biggie left is the forward waste tank replacement. That will be March's project. *

I have a sailboat demanding some of the "boat fund" and time. *Hope that will be it for projects on Moonshine for a while.

Cheers
