Pic of 18LH11 mentioned above

[Discoverie]

I found the prop.
This one available for trade or sale
Shaft 1.5”
Diameter 18”
It marked with
18LH11. I’m assuming that means a 18” diameter, left hand, 11 pitch

Send an email to the list but didn’t see it post, so sorry if this is a repeat.

Timing is amazing. My spare W58 is at Hansen marine awaiting evaluation to determine if it’s worth rebuilding. One of the main problems is parts. I could use an exhaust manifold and the four connecting cast iron parts. I’m supposed to talk with Fred Knowles tomorrow morning about options, and I’ll know more then.

Could you put me down for the exhaust manifold, its parts and the mixer? Maybe more when I hear from Fred.

Thank you

Hoping to revive this older thread. Discoveries’ W58 oil pressure is running at about 40psi—with the service manual specification being 40-60 psi. Towards the end of this season the low pressure alarm has come on, sometimes staying on for a minute or less. Over the last to years the pressure has gradually dropped from about 47psi to 40, so I’m thinking this is a gradule, but definite trend.

Other perhaps relevant facts
The engine runs relatively quitely
It burns no oil and gets around four hours per gallon of diesel
It always starts within a second or two, with no blue smoke
It had a new head as of 2011
Oil Service has been good with new oil and filters at least once a season on very light use, about 30 hrs this year
It’s driven in “baby-it” mode, 5.5 knots max.

Thoughts on gradual decrease in oil pressure
One of two things or both could be causing this trend
Decrease in push side
Worn oil pump
Blockage in intake to oil pump
Increase in volume of pressure side
Due to wear in bearing surfaces

Given the otherwise good performance of the engine, I’m inclined to think this is a worn pump problem.

I’d very much like to hear your thoughts and experience in this area.

Charlie,

Did you check discount marine?

for the 63B four and the 63C four they list this: Westerbeke, Pump, Fresh Water, 32213, 032213

 http://discountmarinesource.com/p-3401-westerbeke-pump-fresh-water-32213-032213.aspx

you might give Discount Marine a call, they have a good collections of Westerbeke parts and might be able to confirm.

I should have mentioned that Bob Fine is the other part of “we” as in we replaced the fresh water pump as spring. “We”…er…Bob actually replaced most of the heat exchangers as well as the raw water pump. His advice in this area is priceless.

I checked with discount marine. It’s not cheap, but this is what they replied:

Hello Roger,

Thank you for your voicemail.

The correct pump for the W60 is part 17752.

That is one gnarly collection of oxides.  I suspect mine (pic attached) was a more recent replacement on my W58. But, based on your picture, I do wonder what’s under the insulation. My picture is collateral from my recent efforts to replace the lift muffler. And yes the coolant overflow line needs to be secured.

yes that’s the guy! Roger Winiarski at Bristol Bronze. I bought a bronze ID plate a while ago from him. Bob Fine also mentioned him. So I rang Roger up and told him about the situation. A rather detailed story followed, here’s the short course.

1) the guy that cast the orginal struts for Pearson (not Roger) sometimes used questionable metal  (“he’d go to the junk yard, buy copper and use that in the melt”)

2) he can definitely do struts, he did a large one for a power boat recently.

3) for our size boats, the cost could be about one boat unit ($1K) for the first one and includes machining and cutlass bearing. Additional ones would be less.

5) he would need a strut to make a pattern from. If it was in pretty good shape, the cost would be less (needs to use it to make the pattern, more prep more cost)

tkx,

It’s not a mold. It’s a pattern that’s used in sand casting. But it is true that cutting a die would be expensive. If you have a foundry, sand casting bronze can be reasonable. Machining is another kettle of fish. 

Bob just reminded me there was a guy in Rhode Island that casts bronze. It’s possible that he might know where a strut (or pattern) can be found. Or better yet a place to machine a casting.

Back on the strut replacement question. I have a friend who is chief engineer at a foundry.  I think they still do prototyping work. If we had a model, I could send it to him and ask if he could cast a replacement. If that worked out, there would still be the machining work, but that should be an easier nut to crack. 

Anyone know where we can get a strut not in the boat? 

tkx,
