With all due respect please do not take me out of context and insult your intelligence by doing so.

First it was NOT a scare but an illustration to show what a potential outcome of home made motor mounts might look like. MIGHT look like...
The part about the washer hole is a 100% bold faced lie with NO factual backing. The FACT is that Westerbeke puts three holes in that bell housing for the express purpose of mating up to various width engine beds. ANY of the three holes can be used and the bell housing is designed for load with all three holes loads in mind. Your statement is 100% false and makes you look....well... I'll be polite....
As I CLARIFIED in post #26 & that image, and bell housing, failed due to a bad casting and was used only as an illustration. If you had actually read the thread
and posts, as opposed to vilifying others, you would have seen that...... I quoted myself below..

This casting absolutely, positively, 150% DID NOT fail due to the hole the motor mount was in so please stop shooting from the hip with your incorrect and absurd "facts".
Westerbeke was kind enough to send me a brand new bell housing at 2870+ engine hours because it was a poor casting
and an original factory defect. They did this because they are a good company. I never asked them for this only to examine the bell housing and give guidance as to what may have caused this after 2870+ hours.
Clearly you need to step it up in the research department before spouting off at other members or accusing me of a bad installation or using the wrong hole in the bell housing.
I have installed quite a few motors and also a fair number of after market & OEM motor mounts. In some instances, especially with Yanmar's, the owners are not as happy with the after market mounts. I have also switched one boat back to factory after going to non-factory and it happened to be a Yanmar. The OEM mounts are specifically chosen for these engines for a reason. The Westerbeke mounts in particular are quite well engineered.
You are also quickly forgetting that I steered
the op to a source for after market mounts that would perhaps cost him less than his DIY idea or damn close, and I was one of the only ones to do so in that thread.
Aftermarket mounts are fine and they can save you money but you may not like the vibration nor find an exact match, bolt pattern wise, to the factory Yanmar mounts.
I have yet to find an after market mount that works as well at reducing vibration, on Yanmar's, as the factory Yanmar mounts do. If you happen to find some please let us know what they were.
Seeing as you have been of little help to the OP, other than to spread untruths and take folks out of context, I will try to help.
This is the motor mount section at Hamilton Marine:
They stock three different brands of after market motor mounts.
Here are a few links that may get you started on your search.
Hamilton Marine Motor Mounts (LINK)
AV Products (LINK)
Globe Ever Stay Mounts (LINK)
The Evolution Company Mounts (LINK)
Having had direct experience with the OP's exact question I highly recommend the factory Yanmar mounts if you can afford it.
