The 1GM10 will fit quite easily but think about the beta as well. Fresh water cooled, 13.5HP and a straight swap.

I used to have an Albin 0-21 engine when I changed to the
Yanmar 1GM10.
I had to build a new engine bed- though it wasn't too
difficult. I did all myself. I don't know about your Volvo,
but I guess the bedding is the same in all Vegas.By the
way, I'm quite satisfied with the 1GM10, but I suggest you
install a riser (about 10 inches) at the exhaust to prevent
water from baking into the engine (it happened to me and it
killed the engine) If you do go for the 1GM10, and need
info about this riser, I'll be happy to give more info.

Hi Wilhelm

The engine beds for the petrol vega and diesel vega are completely
different. I agree that a riser is a good idea when installing in an
ex-petrol vega as the bearers are much lower.

Hello Steve;

I didn't know about the difference in engine beds- now I
know. I had to lower the bed, guess that tells me the
diesel engines sit lower.
About the riser: The mixing elbow of a 1GM10 is quite low.
In my case- I still don't know how and why the water backed
into the engine and totally ruined it (first I thought a
rat had gotten stuck in the exhaust system). Anyway- it was
costly, because I had to install a new 1GM10 again. But
this time the dealer told me about the riser- a vertical
extension of the mixing elbow. It's an about 10 inch riser,
it fits good in the engine compartment. Though the location
of the engine's fuel filter must be changed- no big deal.
On a brighter side- today I was sailing again, Wind
NE-15mph
couldn't have been better....

Kind regards, Wilhelm, V-257

Hi Wilhelm

The diesel Vegas have bearers that are much higher tahn the petrol vega beds
so you do not need the riser. We had a similar thing happen with an
ex-petrol Vega on the South West Coast with water getting back into the
engine. Beta were very good and rebuilt the engine completely for a very
good and fair price. They are certainly a user friendly company!

I am at home with wife and children getting with loads of work to do. Just
had teh bathroom completely stripped so we are plumbing, tiling, decorating
et al..... Also had new doors installed. I am very lucky that Eve (my wife)
is the best builder, decorator and tiler I have ever met. She never cuts
corners and the end product is always fantastic. Just wish I could hire her
out but she insists it is only a hobby!! I was thinking of what bits I
could afforf to buy Southern Comfort is she went out to work!!

When I installed my 1GM10, to replace the 10 horse MD6A on my 1973, I had
minimal work to do on the engine bed. I removed glass down to steel plates and
then tapped new holes for the 1GM10 engine feet.

Hello, anyone have a diagram of the md6, I'm changing engines and need
to know a few things,,,and with the boat on a trailer, with the mast
raised and boom on, can a engine be lifted with the boom? strong enough?
I will secure the opposite side of the boat,,,thanks all...mike

Hi Michael

I lifted the MD6A with the boom once. You will need extra halyards on the boom. I used three, Main, Genoa and Topping lift spaced equally along the boom. I also took all the weight I could of the MD6A e.g. Remove alternator, Dynastart, Flywheel, head etc etc. As much as you can. Also took three guys!!

Cheers

Assuming your lifting tackle is out at the end of the boom, the boom is only in compression, with no bending forces on it. You're better off attaching all topping lifts, halyards, etc out at the end where the lifting tackle is attached. The further out from the gooseneck they're attached, the more they'll contribute to your safe lifting capacity. It's also good to back up the gooseneck fitting with a line in case something there lets go... Haven't done this with the Vega but it worked smoothly pulling an Atomic 4 out of an Alberg 30...

The yard where I did the repower had an extra tall forklift (Blue Fin
was on her trailer). We attached a chain to the forklift and lift
point on the MD6A and it was no problem. Cost was less than $100 USD.
Worth every penny.

Does anyone have a good injector pump drive gear for a MD6B for sale?

Sorry,
I have been sick and just saw this message. Our MD6 had a terminal illness
and was removed by a crane by the yard but the crane had broken and it would
have been weeks before repairs to the crane to lift the Yanmar GM10. And we
were stuck in Florida at the start of a three month cruise with no job, money
going out, and no place to live.

I decided to use the boom, topping lift, and main sheet to lift the 225 lb
(100kg approx) weight about eight feet (2.5 meters) onto the boat. I used
extra jack stands to balance the offset. Everything did go smoothly.
This was a bit of a desperation move but I did check that all the
components, lines, blocks, shackles etc were well above the load stated.

It can be done.
