The purpose of this thread will be to consolidate all of out collective research and experience we have on sourcing "good enough" parts instead of paying a 500% premium for red paint.
For ever entry made here please include the following:

The model and year of generator
The OEM part number if you know it
A description of the part in question
your sourced alternate part
some link or contact so others can get it.

Let's try to not clog this one up with questions about parts, just answers. Questions can be asked as usual in this forum, or in other forums. You can point others to this thread.

Thanks for your post. What I am hoping we can do with this thread to set it apart from just general replies is to be specific about the year and model you are reporting an alternate part on, and include that in the post. That way, we don't have to sift through what will likely be hundreds of posts just to find a specific application.
 
Does anyone know where I can find an aftermarket engine block for an 2011 Westerbeke 5.0 BCG gas generator? Westerbeke wants $3,600.00 for the block...ugh.
 
I have a 2001 era Westerbeke Governor, I rebuilt but never used. New bearings and seal. They are very hard to find but replacements cost $2000.

If someone is looking for one, PM me.

Thanks, LG111, I ended up finding one for $1,000. What size is your generator?

If someone is looking for one, PM me.

I no longer have the 410 but I think it was a 7K low RPM westerbeke. The only difference between the low RPM and newer Higher RPM Governor is the wheel size on the shaft. The Governor is one size fits all.
 
I’m looking for a 4.5 2cyl exhaust manifold. If anyone has or can find one
 
Also, I have the bearing numbers for our Governors for those that have the equipment to press one on
 
Does anyone know if there is a different manufactor’s controller that will replace a Westerbeke controller govnr 12/24 no over 046945. Westerbeke wants $325.00.

year & model of generator
some photos of the controller (without the cover if possible, get photos of the board
There are many generic electronic governors available, but there would be some adjust. setting, etc to workout.

original looks to be a Woodward DPG-2133-002 new all are $300+
used one on ebay now for $150 use above to search
generics (china cheap) are 50-60 it would be an experiment

Thank you so much for the help; I ordered the unit off eBay, keeping my fingers crossed, and will report back with results.
