A PO replaced the head in my boat with a Dometic portable toilet.

It fits in the space well and gets the job done. Any portable toilet would probably work. Given the height of the base and a typical person's height, a 5 gallon portable toilet is what you need. A 2.5 gallon would be too low and make it difficult to use.

I think I might replace the wall and door to the head before worrying about the toilet !

actually i think replacing the toilet first would be a heck of a lot easier w/ out the constraints of bulkheads. would a traveller head work? many trojans had this set up. it's an internal holding tank of 9.5 gallons that can be piped to the deck pump out or, the plumbing can go from the internal tank, to a holding tank in the bilge and then a deck pump out. a hand transfer pump or a 12v macerator transfer pump from toilet to bilge holding tank. with the head being so open, you have a good opportunity to work on this.

Thanks for the input on the head.

Next question. It was rebuilt with an internal regulator. Red from battery to nut. Does green just get grounded to anywhere (the block)?

Thanx again

i'm confused. what in heavens name is that ? i did a google search for SAE J1171 MARINE and all sorts of things popped up. one of them says it's a 'mercury tilt motor'. why would there be a tilt motor in a shaft propelled boat?

I brought my old own in to be check. He said it was good but did not have the
spark arrestor on it. So he put one on. He he said this one had an internal
regulator.

It's a alternator

Aaron "SAE J1171 " is a marine safety standard . Basically it means ignition protected so you don't go boom .

ahhhh, sorry fellas.. a little, no a LOT of jetlag from these past few days. just be patient. to be honest, i've never seen an alternator from that point of view. i'm feeling a little sluggish today.

Don't hook it up yet

That green wire is something that has been added . Check with your rebuilder . That alternator is a one wire Delco SI 10 ( or 12) with a internal regulator . All it should need is the one wire (B+ ) and your good , unless your re-builder used a different reg then what it came with.

A note on the 1 wire alternators , to get them to start charging you may need to bring it up to 1500 rpm for a second or two to excite the alternator then it will charge at idle .


And put some selant around where the geen wire come throught so it stays "ignition protected " shame on your rebuilder .

Let me know whay he says about the green wire .

Talked with the shop who rebuilt the alternator.
They said to hook power to nut. The green wire can go to a tach.
Or don't use at all. Will silicone around green wire.

This is the side that water stops flowing after about 10-15 min.
I scraped some carbon out of the top end cap.The exhaust manifold seems
to have some clogged ports. Any ideas on how to clean them up.

[vabeach1234]

I would recommend buying new ones. Manifolds and elbows. I've heard of some people removing them and soaking them in something but not sure what. Worst case scenario, the water leaks from the cooling passage into the exhaust side and water gets in your cylinders, then you pretty much destroy the engine.

Unfortunately it would cost you over $500 for a new set of manifolds and elbows.

If your engine is raw water cooled the top round hole should be the only one open. The other longer holes on the side and bottom should be blocked by the gasket.

Open gasket for raw water cooled engines:



Closed gasket for closed cooling system.

[vabeach1234]

I just did an internet search and people have soaked there exhaust manifolds in muratic acid to clean them. But I still think replacing would be better. Life expectancy of these are around 5 years on a raw water cooled engine used in saltwater that isn't flushed after every use. Yours looks like it's near it's end of it's useful life.

[Sanctuary 2]

What would cause the water to stop flowing on this side?
Engine fresh water cooled. I'm sure exhaust is raw water cooled.
Are manifolds raw water cooled?
