Re: Yanmar Terrible Rumble/Grinding Noise On Initial Engagement

The oil was clean and not dark as the engine oil gets, even when it is quite fresh. I think everything is OK in there. I have a minor concern about the linkage and will get around to inspecting it better.

Stepping the mast manually is cheap and reasonably easy, but it's not for the feint of heart!

Re: Yanmar Terrible Rumble/Grinding Noise On Initial Engagement

I lubricated the shifting control and cable as best I could today. This did not help much. I've not disconnected the linkage from the cable yet (hard, painful job) but I'm assuming the cable is probably shot.

The control is Morse (Teleflex/Morse) and was original with the boat in 1978. I have some documenation for it, which I'll try to remember to grab Saturday.

Does anyone have any ideas on what this part number would be?

Re: Yanmar Terrible Rumble/Grinding Noise On Initial Engagement

Teleflex/Morse cables are pretty standard. Might need to use the end fittings from the existing cable, but otherwise, just need to order the same OD cable in the correct length.

Re: Yanmar Terrible Rumble/Grinding Noise On Initial Engagement

I confirmed that the problem is the cable. I'm pretty sure this is a Telex 6400BC cable with the 5/16" connections and the bulkhead connector on one end. Unfortunately, these cables run about $150 vs. about $45 for the lesser 3300 series.

I'm going to attempt to remove the cable from the boat tomorrow. Today I took both ends off, which was not difficult. I expect the bulkhead connector to give me a fight as it is severely corroded. It's been getting penetrating oil for a week. Anyone know what size these nuts are? They are bigger than 3/4", which was the largest I had on hand. I can use two large adjustable wrenches but I think it may take a hacksaw.

I can't really measure the length of the cable without removing it, though I'd guess it's 6'. Lengths this short are not readily available and I may have to put in a loop, which will add pi x 16" to the overall length.

As difficult and as expensive as the cable replacement will be, it is way better than having faults in the transmission.

It looks like you have got your work cut out for you (pun intended), I don't envy you.

I don't like the "kink" in the cables at the throttle/shifter end. Hopefully that can be made more fair / true when you replace the shifter cable.

Crustations, probably tube worms, have built shells inside your stern bearing.

Re: Yanmar Terrible Rumble/Grinding Noise On Initial Engagement

I received the Teleflex/Seastar cable Thurday afternoon and installed it Friday. The installation was straight forward. The only hassle was dropping the pin that connects the cable yoke to the shifter mechanism. Of course, if fell right into a place you can't get to. Fortunately, a 5/16" bolt with a nylock nut works just as well and now I won't have to hassle with the tiny cotter pin that went into the pin.

The new cable shift smoothly and easily. The transmission engages perfectly in both direction. This one is wrapped up and it's time to go sailing!

Re: Yanmar Terrible Rumble/Grinding Noise On Initial Engagement

Glad you got it sorted Homer. You have prevented accelerated clutch wear.
Bad luck that lubing cable didnt fix it. I took one off on a previous boat & hung it up & drizzled oil down it for a couple of days to free it up. Worked until we sold boat a few years later.

Still if yours was original cable I guess 43 years aint bad. Reminds me I better lube our 1980 cable.I guess they will be over $300 here if they are $150 there.
Sail on.
