Single vs twin engine boat

[markizok]

Hello. We have a single engine 28ft boat and we are considering upgrading to 36ft and there are two engine options - a single D6 or twin D3.

Gut feel is the single with a bow thruster as it should be smoother with just one lump to maintain, however twin engines have the benefit of a backup motor if one packs up - unlikely I know but it’s something we do think about.

Thanks

Twin D4 an option?
D3s are a small capacity high revving engine.

It will be used, but it seems the options were a single D6-400 D6-400 or twin D4-300. Obviously more power with the twins....

It was a Sealine SC or C, but recently I read a lot about Marex - seem to tick our boxes, but are more £ than we planned on spending!

That’s my impression. The 375 is great but quite looking forward to seeing the 330 Scandinavia!

Don’t get me started on outboards - got a real thing for the new twin regal, but budget won’t allow!!
