I had to get new spreaders fabricated for my 1965 Tartan 27. The shop was able to contact Tartan directly and get the specifications.

Thanks! As noted above, I know just enough to be dangerous. I can see how things *could* be a problem, but I lack the experience to know *if* they are really a problem.

Alas, this just adds to the confusion! It would seem to imply that people only want to face split couplings but not solid couplers. But it is my understanding that with a standard solid coupling, the...

Thanks everyone!

I totally agree that there is no point in checking the engine alignment until the boat is back in the water.

The concern is that if the face of the coupling is not...

Should I face the split coupling?

I have two questions.

I am replacing pretty much everything astern of the transmission coupling -- a new shaft coupling, a new prop shaft, a new stuffing box (the hose, the bronze parts, and the...

Agreed.



So, perhaps the problem is trying to use an alternator that is designed for use with an engine. What is needed is an alternator that has peak performance in the 700-2000RPM range.

Hmm. 100+ amps @ 12VDC would be meager 1200W. If that is a reasonable upper limit, then I might as well just use my Honda EU2000i as the 'stop gap' measure for experimenting with electric.

Atomic 4 -- generator conversion

Ahoy!

Like most sailboats, the engine in my Tartan 27 is designed to provide a lot of propulsion and a little bit of electricity.

But a vast majority of the time, I only use the engine to motor...

All I know is that *some people* claim that the 'press fit' shaft coupling can only be used once. And that if you use it multiple times, then you risk having the propeller shoot out the back of the...

Truthfully, I'll probably put in a new shaft regardless. I am having a harder time deciding on the PSS.

On the one hand, the PSS sounded like a good idea when I feared the stuffing box. But now...

Hmm. Interesting idea. I am going to have the boat out of the water in a month or so anyway. I assume it is necessary to remove the shaft from the coupler so you can get the old hose off and the new...

Probably. There is over a foot between the current stuffing box and the engine. And there are a couple inches of free space around it.

Ok. I'll stay another day and repack the stuffing box. (Another first for me!) Pretty sure I can get the flax at the ship store here.

So, I managed to get the coupler separated by around 0.028" and use the feeler gauge to check the gap. It seem pretty even all around. I rotated the coupler and the flange around and the spacing did...

Nice. Are you concerned about that scratching up the faces? Or do you use it when you place to replace both halves anyway?

Drive train noise, stuffing box leak, etc

When motoring, I feel that the noise coming from the propeller area is a bit excessive -- sounds like I am on a B-52 bomber. But this boat is new to me, so I don't know what 'normal' sounds...
