Engine mount replacement

[vic008]

The front rubber mounts on my 2003 are not what P4E show.They are actually 2 seperate pieces, one a vee shape and the other accepts it. Therefore the front of the engine is not actually held down. No, never found another source

Sounds odd. Got a picture?

Have pics but uploaded file too large.How to reduce?

reduce your image size.

The Volvo Penta parts diagram shows different part numbers for the front and rear mounts, so I'm surprised that P4E just offer one type.

Hello guys, it's been a long time since this topic was started, but I'm having problems to find proper engine mounts for Volvo Penta 2002.
Did anyone found a replacement engine mounts for this 2000 series in last 11 years?

In my case , the rubber on front engine mounts delaminated over time, so I get excessive rock when I start the engine. Also, I get some clunking sound from time to time, like when the shaft is out of center....

It would be worth checking the condition of the rear mounting brackets. Originally these were pieces of bent steel, but they had a tendency to crack, so have been replaced by cast metal brackets.

i reccomend Polyflex mounts, i got exact replacements for my yanmar 2GM20, im sure they have them for other brand engines

I know about the front bracket with rubber mountings, but I haven't noticed rear bracket at all? I'll check everything more thoroughly...Polyflex mountings are something that I heard of, but I'm not sure about shipping.
In the worst case, I can remove my mountings and send it to afactory which refurbishes mountings, but I'm not very happy to do so because the lifespan is really low, like 2 or 3 years.

Thank you all for helping, if I come up with something and solve the issue with new mountings, I will let you know.

Here is my experience after a year with engine mounts for Volvo Penta 2002. I found out that old Audis 80, 90, B3 use almost the same engine mounts as Volvo Penta. Maybe that's not something to recommend, but it does work.

This is the OEM number: 30130012
It was used in Audi 80, 90, B3 between 1986-1991.

You can find it anywhere and it's really cheap, for around 8-10$ per piece.



What I had to adjust was:
- make new holes below rear mounting plates, because of the bottom screw on the mount so it can fit
- front engine mounts were wider for like 6-8mm, so I had to cut the sides of the mounts with angle grinder

When cutting the sides I was taking care not to make them hot and delaminate, so I used water to cool it down.

There are no downsides except this mounts seem a bit softer so engine wobbles more on the idle only, but it doesn't pass vibrations to the boat itself as it did before. I didn't have option to buy neither original or replacement Volvo Penta mounts so I decided to try this out and I'm quite happy how it works.

Here are some photos of the old one and new.
Cheers!

That's interesting, thanks, but am surprised the car ones work as they are not designed to take the thrust like the marine ones are.

Fair point Plum. That's why I checked these with experienced boat mechanic guy so we compared both before installing and couldn't find any cons to these Audi mounts. Thickness of the metal housing and rubber element is even higher in the new ones. This kind of mounts is really simple and not so easy to fail. Basically rubber between two metal plates is what takes the thrust so even if delamination occurs, it will push the boat but can cause engine and shaft misalignment.

So far, 50hrs in one year without noticeable issues. The boat is Rebell Seaskip II, 25ft

All engine mounts take thrust, even ones in cars; the rubber sandwich is physically all but identical so unless the shore rating of the rubber is wildly out they will do admirably. Most of what you get with VP is a large premium for a coat of green paint.

Going back to the Volvo 2000 series engine mount question, is there an alternative to the Volvo mounts? These seem to cost over £100 a time (at least for the 2003) for what appears to be a lump of rubber with a bolt sticking out of it.
It's possible that the rear mounts can be replaced by generic ones, but the front ones appear to be mounted upside down to the engine, and to the engine bed via an angled racket (see http://www.marinepartseurope.com/en/volvo-penta-explodedview-7726000-21-11600C.aspx)

Anybody got any ideas?

Considering the prices I am reading, "angled racket" seems quite apt ?.

But the mounts in cars do not take the thrust of the driven wheels pushing the car along. On the vast majority of boats the prop thrust pushes the engine which pushes the hull via the engine mounts. (In both cases the mounts transfer the torque)

 

[penfold]

Even a 2003 isn't going to be generating more than ~150kg of thrust at full throttle, or for the layman would you feel confident hanging your bodyweight off four of those mounts?

I've heard good reports or AV Industries/industrial. Tell them your engine and they'll do the rest.
