Volvo Penta D2-75 Vs Beta 75?

[vquinlan]

We are replacing the engine on a Bruce Roberts 43 (Mauritius), she about 18tons.
We now have it down to either a Volvo Penta D2-75 or a Beta 75. They are coming in at much teh same price, but we are getting much better feedback from Volvo - more attentive with quotes/questions/etc. Can anyone out there help with their experience with either engine. All comments appreciated. Both engines are new. We intend to keep the origional v-drive box and have it refurbished all else will be replaced exhaust/gearbox etc.
Thanks,
Vera

I have the D2-55 which is exaclty the same, less the turbo. I can only praise how good this engine is. Bear in mind for your calculations a cruise speed around 1600-2000 revs. Do not plan to ever cruise over 2000 revs even if it can reach 3000. It does not have an overhead camshaft, but rather pushrods and levers.

If the VP has a turbo and the Beta has not, that may be a suggestion to go for the Beta.
Turbo on a sailing vessel engine is not ideal. It adds complexity.
Then again, if you plan to sail large distances, the service network for Volvo may prove much better.
On itself I've heard many good things of the D2 series from Volvo Penta so I don't think you would make a bad choice with VP.
You could also compare the price list for spare parts. Since VP once tried to get over 700 Euro for a fresh water pump, I've become a bit allergic to spare parts.

Cheers,

Arno

thanks Arno - yes the VP does have a Turbo. We do plan to sail long distance so thanks for suggestion will look at both service network and spare parts costs.

Good to hear you have had good experience with yours 'Haydude'. One question the engine spec says max rev 2700 - 3000 but the Beta says 2600. I understand from this if I go for the Volvo I have a higher reving / fast engine?

If you need the full power output then you need to look at the rated revs and prop the boat correctly to achive this. In terms of life there won't be any real difference between the two engines even though their maximum revs are a bit different. It does though usually mean that your cruising revs will be lower with the lower max engine. As you are re-using your gearbox you are stuck with the reduction ratio you have, but the prop size will be different between the two engines (and probably different from your existing engine) so you need to check that you can fit the right prop to match your chosen engine. Like others my preference would be for a non turbo engine for a sailboat auxilliary, but if you spend a lot of time cruising at usual cruising revs (+/- 70% max power) then probably not so important as the turbo is working at those revs.
