Hi all. I’ve just got my self a Virgo voyager with. No motor. I can get a yanmar 2gm 20f motor. Has any one any advice on this.

2GM20f will be fine. Is the shaft and prop still in place - if so make sure you fit a propeller that is correct for your new engine. Seem to remember they had Bukhs when new so expect to do some modifications to the engine beds to get the engine to mate up with the original shaft.

Ye shaft and prop are there,thanx for the info.im going to give it a go.

Far too big in my opinion.… I had a Virgo Voyager with a 9 hp Volvo fitted. Which worked very well. I wouldn’t consider anything bigger than about 14 hp

The 2GM is only 16hp continuous, 18 maximum. The extra power is not excessive and the Yanmar is a good engine. with an appropriate prop it will cruise at 2600rpm which will put enough load on the engine with plenty in reserve. One of the Voyagers currently for sale has one fitted. While a Beta 14 or 16 would be adequate they are as rare as hens teeth secondhand and more than the boat is worth new!

Tranona may well be correct and that engine would work. Although it doesn’t sound ideal to me.
I would be very cautious of fitting any second hand engine. Been there. Done that … boat engines are second hand for a reason. Often because they are getting worn out.
Actually, if I had an engineless Virgo Voyager I would give serious consideration to using an outboard motor. A 6hp motor on a bracket could be a good option for all sorts of reasons.

Hi it’s a recon. wat would (all sorts of reasons). Be. Thanx for the information so far

All sorts of reasons … well the outboard is likely to be much less expensive. There is no cost of fitting except maybe to screw a bracket on the stern. … if it goes wrong you can take it home to fix it. Or just buy another one and clamp that on instead.

Perkins 4-107 ... taken out of a Rustler 30 ... sat on a pallet back of HYCO shed for a couple of years ....
Guy I was told took it out as it smoked a bit ... replaced it with a new Beta.
My 4-99 was seized and the 4-107 dropped straight in.
Gave it a real thrashing and it blew all sorts of crud out ... and its still in my boat approx 15yrs later ... runs sweet as a sewing machine .. starts without cold starter ... chugs away all day ...
Best 250 quid I ever spent.

Personally having gone down the road of change to outboard or replace inboard ? I went for inboard - glad I did.
I'd had boats before with outboards - strained back humping on / off brackets ... had a couple of times where outboard was swamped by boat pitching heavily ....
Inboard has much better higher power charging for onboard batterys etc.
Diesel consumption is low.
As to power ? My Sunrider 25 has a 43hp 4-107 ..... I am very glad of that power - even though its more than 2x size of a capable unit.

Many years ago, I had the unusual combination of a fin keel Virgo Voyager fitted with a 7hp Vire petrol inboard engine and a fixed two-bladed propeller. With a clean hull at the start of the season, she would do about 5kts flat out and cruise at around 4kts. However, by the end of the season, with a bit of growth on the hull, both figures would be down by a knot or so and I would wish that she had been fitted with the diesel option. Most other Virgo Voyagers came with bilge keels and a Bukh 10hp diesel inboard, fitted with a fixed three-bladed prop. The Virgo Voyager has a LWL of 19'10", giving a theoretical hull speed of around 6kts, which the extra grunt of the diesel option should probably get the boat closer to. Your 18hp engine does sound a lot by comparison but, if it will fit in the engine bay, give it a go - I've never met anyone yet who has complained that their boat has too much power...

A 1GM10 would do a job but if the 2GM on offer is a good price, then go for it.

I'm trying to figure out how a diesel engine would overcome hull growth ? The Vire 7 was a good little engine and leagues better than the older round pot 6 ...
My Snapdragon 23 had a Vire 6 that the crank seals gave out in ... sold it on to a couple of guys who wanted it for an open boat for fishing in Newhaven. They replaced the seals and it ran sweet.
I wanted to fit the new 7 but it would need modification to mounts / shaft coupling etc. Another guy in the Club was replacing his Mini Petter and I agreed to buy of him ,,,, but the Engine suppliers he got his new from pushed him to part-ex the Mini Petter to them - incidentally they gave him less for it than I would have !
So I decided to fit a lifting bracket and outboard as that was easier. I blanked of the shaft hole.
That was probably the worst decision I ever made ... I should have gone for the inboard ..

There was nothing wrong with the little Vire 7hp, as you say, it's just that the 10hp Bukh had 43% more horsepower! That should go some way to overcoming a bit of hull growth, I would have thought...

Hi all: thank u you l all for the feed back. Looks like I’m getting the 15hp yanmar (reconditioned) now——- which gear box +3/+2.? I have a two bladed prop.

From memory the Yanmar box comes with a choice of forward ratios, 2:1, 2.65:1 and 3.1:1. it is really important you know exactly which because the propeller size will be wildly different depending on the ratio. For example with my 1GM which uses the same box, with a 2:1 the diameter was 11", but when I changed to a 3.1:1 I used a 14" fixed and then a 15" feathering.
Ideally for the Voyager you should have a 2:1, although you could get away with a 2.65:1. To get an idea of the size required use this propeller calculator programme.vicprop.com/displacement_size_new.php/?m=1

I had a virgo voyager for a short while with a 1GM10 which was plenty of grunt to get to hull speed without stressing it. A bigger engine would just be unnecessary weight to carry around. I'm 100% not in favour of outboards on the transom of sailing boats at sea. In a boat with a cockpit well it could be ok but even then I wonder about water sloshing around it if working on it at sea. Stick with an inboard diesel IMO
