Volvo D1 20 Info required

[wizard]

Having changed boats my new one has the above engine and a saildrive. Up till now I have always had Yanmar engines so back to beginner level for Volvo.

I had a fuel usage curve against revs for the Yanmar does a similar exist for the Volvo?

What is the most economical revs for motoring?

Are there workshop manuals available?

Any other info would be useful especially any little problems or things to look out for.

Ta in advance for all help

VP owners manuals can be downloaded from http://www.volvopenta.com/volvopent...lication_search/pages/publication_search.aspx

Workshop manuals have to be bought unless you can find one on a website somewhere.

We have the next one up, the D1-30. I assume they're similar. Good engine overall, I'm told it's a "Japanese Perkins" underneath the Volvo green paint. Very little vibration when running compared to our previous Yanmar.

There is a fuel curve available; I don't have a link but my Dad found it so it must be reasonably easy

We cruise at 2200 revs, though you'll want to check this for the 20 vs the 30.

Workshop manuals are hard to find, unfortunately - nothing like the Yanmar. In particular I have never found any official information about the electrical system on the engine.

I can't think of any gotchas or vices really.

It comes with a sump pump-out point already fitted, which is a nice touch. There's a second pipe below the dipstick tube, roughly in the vicinity of the oil filter, with a little rubber cap on the top.

Thanks Vic, very efficient as usual.

Thanks Pete I will search.

Btw seems a long time since the few made it to Cherbourg last September!

Maximum revs is 3200. It should be propped to achieve hull speed at close to that figure. Cruising speed is at around 70% of max power, which as Pete suggests is approx 2200 rpm which should give around 5.5 knots and about 1.5l per hour.

That's good - not having any figures at the time we selected it based on how the engine sounded and the boat felt

Our D1 30 with VP three blade folder driving a fairly slippery lightish 33 footer (Finngulf 33) all sails down, averages a wee bit less than 2 litres per hour at 1950 revs. in flat water giving 5.5 kts, if the wind is stronger with a bit of sea 2200 gives about the same but burns about 25% more fuel, at just over 3000 revs it can manage about 7.2 kts but is burning just over 7 litres per hour.
