Perhaps if you consider buying a D1-30, it could pay off to look at the sourcing and selling/ trade in of your MD2030 and saildrive. as example:

Good luck with making your decision!

Pretty sure it is a direct replacement. I have had both engines and there is little to choose between them in terms of performance and refinement except that the D1 runs at lower rpm (max 3200 rather than 3600) and has a larger 115A alternator The 130 drive is much improved, particularly the larger and more easily replaced anode.

The Perkins is the same engine but downside is that using the 120 drive means you will have to change your propeller. The 120 has a 2.47:1 reduction and the 130 is 2.2:1. so when you mate to a 3200rpm engine the shaft speed drops from 1470 to 1295. Also you are reusing a 25 year old drive and while it may last spares are not available and failure means a new 130 drive which will cost much the same as the difference between the engine only price of the Perkins and the complete Volvo package.

You should be able to negotiate a trade in discount with the Volvo dealer or free fitting  as the 120 drive alone has a value because of the non availability of parts. Volvo may also still be offering a 5 year warranty on new engines and drives.

If you intend keeping the boat then maybe a complete new system with a manufacturers warranty is the way to go.

[But my biggest question is has anyone replaced MD2030 with D1-30?]

Bavaria Yacht Help! / MD2030 D1-30 motor replacment

Last post by marioxp - April 01 2026, 10:39

After I did a major service on the engine and replaced practically everything, pistons, bearings, pumps, cylinder head with valves... After 400 hours of operation, problems with starting, low pressure was measured in one cylinder, shims were found near the valves. I decided to replace the engine.

In Croatia, I only have a few options. Perkins engine 3.29 which is marinized by a company in Croatia (they have more than 30 years of experience and very good recommendations) and the other option is Volvo penta d1-30. Perkins engine is around 6,800 eur and d1-30 12,300 eur (VAT included), with the big note that d1-30 comes with sail drive and for Perkins I have to use my own gearbox and sail drive. The price difference is huge but I get the whole set from Volvo.

But my biggest question is has anyone replaced MD2030 with D1-30? Are you satisfied, do you have any problems?

I'm worried if the mounts are the same.

I am attaching pictures of my engine mounts.

Have ordered a new Vetus anti-siphon valve with hose which is a much better solution than the current device!

There should also be a hose from the valve part of the anti-siphon valve guiding any water down to the bilge, instead of squirting it all over the engine. The small hosetail: https://webshop.vetus.com/en/product/asdv-anti-syphon-device-with-valve-13-32-mm

Mine had a little bottle tied to it, so I know when the valve needed cleaning. Also less mystery leak hunting that way.

With regard to the anti siphon valve.. the latest VP model is creating far less problems than the old model. If you can spare the money, would recommend to exchange for the latest VP model.

The anti siphon valve only needs  maintenance. Take a look in the manual, its easy to do.

Thanks again symphony2 another good suggestion. I have found the source of the problem, the anti siphon/vacuum valve is dribbling water at idle and supporting it out at anything over 1500rpm. Of course this is going over the fuel pump etc on the starboard side of the engine. Will install a new anti siphon valve and hope this fixes the problem.
