Not sure why you need an automatic fire extinguisher just because the ambient temperature (or engine room temperature) is high. It is there to deal with fire which is more likely to be an electrical issue. As suggested the activation temperature is far higher than the temperature during normal use.

Hey there, I have something like the below for Mirage in the UK. Being clean agent, and not powder, is much better as if it goes off accidentally, it will shut down the engine, but it won't kill it. Dry powder will be sucked into the intake and will damage the engine.

Activation temperature is around 68 degrees C - I would put a heat sensor in your engine bay and see what it reaches. I doubt it will get that high?

We would like to fit an auto fire extinguisher in the engine bay of our B34 sail boat.In view of the seemingly high temperatures that occur in there(air temp here in Spain can reach 40 degrees) plus engine related heat.
Does any one have any advice or suggestions for any equipment that will cope in these  circumstances.
Thank you

Modifications & Equipment / Re: LiFePO4(LFP) battery upgra...

Last post by symphony2 - April 04 2026, 12:50

Welcome

That is a huge amount of capacity for such modest usage - something like 5 times as much usable capacity as the original. How are you going to charge it? Do you have plans to live aboard for long periods away from shorepower with increased daily usage and a lot of solar to keep pace with consumption? Windlasses and bow thrusters are normally powered by the start battery in lithium installations with an interlock so they only get power when the engine is running.

Modifications & Equipment / LiFePO4(LFP) battery upgrade

Last post by azuro - April 04 2026, 08:06

Hi, all. I am going to upgrade to 2x314Ah lifepo4 battery pack w. OrionXs50A dc charger for my B42Cr, 2006 sailboat. Since I am not an electrician but diy sailor, I am looking for a typical diagram. Very basic usage for now, only the fridges, windlass, coutesy lighting, etc.  Just went thru the forum but not a complete answer.

I appreciate advice, experience but a full diagram from the community. Thanks.

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!
