Beta vs Vetus vs Yanmar - re-engine Moody 33

rustybarge said:
Outdrives/outboards seem to handle storm force conditions on pilot boats/ ribs without any problems, and the prop can be out of the water for considerable amounts of time.

If you fit a small OB close against the transom, it'll look fine. As you say, Fitting it hanging 2' off the back of the transom will look wrong.

Small outboard? You said 30hp, that is going to hang at least 2ft off the back and No way that is going to use the same amount of fuel as diesel inboard.
 
Outboard over stern had that on my last boat. Great but to exposed on small boat as there is a significant value to be had in small O/B the cost of outboard is significant part of boat.

Taking my present 35' boat over the stern it would spend 1/2 its life under water. I would want to carry significant amounts more fuel bigger engine and bigger and boat bigger range. I do not want that much petrol onboard.

I could consider outboard well, but then it takes space in the cockpit and is significant extra drag...

At 4k for outboard + 1k for brackets cabling modification. Yeah you might save 5k, but would you get a buyer when it comes time to sell?

Also outboard are usually poor at charging most people opt for bigger and second altinators to give extra charging ability. All lost on O/B.

There is a diesel engine available in this format its called a sail drive, although personally I would rather pay the extra for shaft (One hole for prop easily plugged). Although many would debate this too...

I am reading thread with interest as I have an Old 2GM20 at 30 years old it might not run for ever. As I see it Yanmar do a 3YM20 that would almost be a direct replacement. Even an idiot like me could do???
At 6k that would hurt but not tooo much...

Perhaps because they have never made much impression in the UK market where the replacement sector is dominated by Beta and Nanni. Nothing wrong with the engines, just difficult to make headway against two very well established competitors.

When I went through the process of assessing replacement engines the Vetus was certainly competitive in price. The biggest turnoff was a complete lack of interest/knowledge on behalf of Vetus. No doubt they have knowledgeable people but finding them is too much hassle. As I was installing the engine myself I wasn't prepared to take the risk of needing to ask a question and having no-one to answer it. Beta, on the other hand, are willing and able to spend as much time as needed to answer and explain any queries. That is where Beta score.
 
Hi Nick,
I'm looking this two engine: Beta 30 and VETUS M3.28

I can ask you where are you find this price ?
maybe can you write me a private message...

Thank you
Cheers
Luca

Dear all

A terminal problem on my venerable Thornycroft T90 BMC 1.5 has meant that I have brought forward a long held desire to re-engine my Moody 33 Mk II.

Best quotes for 3 suitable replacement engines - each about 30hp with a suitable gearbox - inc VAT are:

Beta 30 - £4855
VETUS M3.28 - £4840
Yanmar 3YM 30 - £5604

Parts I reckon I need to add are:

Coupling
Propshaft
Propeller
Cutlass Bearing
Siphon break
Instrument Panel
Mixer Box

which will come to about £1500 inc and I reckon about £1000 to fit working with the local fitter.

Any advice on which engine, or any particular pitfalls to be aware of?

Many thanks

Nick

I asked a number of marine engine workshops which engine they had to repair least and the Yellow jersey went to Yanmar. Anyone thinking of buying a generator the Yellow jersey went to Northern Lights with Westerbeke a close second.

I fitted a Beta 30 to our Roberts 34.
No problems but the weight was an issue causing the rear of the boat to squat down. I also don't like the Beta switch panels but that's a personal choice.
I've no experience of the Vetus engines.
The Yanmar would be my preference. Much lighter, compact etc.
The first step would be to check the engine bearer arrangements and how they would match up with a new engine.

Compared to the T90, most of the new engines will be about half the weight, we replaced the T90 on our Moody 36 with a Beta 38 and have been very happy. Increase in space in engine room makes access to far side of engine a piece of cake. At the end of the day most of the new engines are much of a muchness IMHO, down to personal choice really.

Can't comment on price my re-engine came in at about £7K excluding prop but including all you extras.

No idea, I love my vetus. More important is making sure that the service access for the chosen engine works for your boat. The vetus engine is a Mitsubishi base engine and they seem to be very reliable.

My Thorneycroft T90 broke this year so I removed it in the Autumn. I installed a Yanmar 3YM20 a few month ago. Did the whole job on my own. Cost £4500for the complete brand new engine, gearbox, and feet from Ionion Marine, Preveza. I have kept the same prop and prop shaft. Bought a coupling and alignment absorber thingy including the bolts plus the stern gland hose from T Norris for a total of £78 including postage and VAT. I also had to buy replacement control cables from the chandler for 25 euro's because the engine is a lot smaller and the old cables didn't reach the gearbox and throttle. I retained the mixer box but needed to buy half a meter of exhaust hose to connect it to the engine. Engine still pristine brand new and untested waiting for Spring when I put oil and water in it, connect the input sea water hose then fire her up before launch. Then I will strut around the Boatyard with a big smirk. (I hope)

Either the Beta or the Nanni equivalent. Nothing wrong with any of the others (or indeed a Volvo) but the Kubota base engines are probably the most popular in the re-engine market.

Budget to replace the complete exhaust, new inboard seal such as a Volvo, a water inlet strainer, engine controls and cables and worth fitting new insulation while you have the engine out. The instrument panel comes with the engine and you will have a choice of types. Worth getting one with a rev counter. Consider upgrading the charging system with a split charge and dedicated engine start battery if you have not already done so. All the new engines have a narrower mounting base so you will need to modify the engine beds. Your supplier will be able to advise ways of doing this and Beta for example sell a kit for the job.

Your "extras" budget is a bit light and you will find £2k more realistic. Fitting is a very straightforward job. You are lucky in that your engine bay has plenty of room - the new engine will look lost - better to spend the money on bits such as a feathering prop rather than pay somebody to do the job.

A mechanic told me that Lombardinis were a direct slot-in for Perkins.

If I was looking for a replacement for my Perkins Perama which I am not at the moment then besides the usual suspects I would give this contender a good tyre kicking.http://www.craftsmanmarine.com/propulsion/engines/cm327/ The basic engine is Mitsubishi but underneath beats the same heart as Beta/Volvo /Nanni , engineering looks excellent and could be a shade cheaper.

Not the same engine at all. Beta and Nanni are Kubota based and Volvo is Perkins. Vetus (another Dutch company) also use Mitsubishi.

I did this exercise a few years back and fitted a Beta 25hp which is more than adequate. Mine is a Moody33 mk2 and the problem is that you cannot fit a larger prop than 13" diameter otherwise you carve a groove in the hull. I did extensive research and unless you realign the propshaft to a greater angle you are stuck with 13" max prop diameter.(there is a boatyard in Wales which realigns the propshaft and fitts a larger prop with a Yanmar engine). Even at 13" in theory it's tight.
Beta will make the engine mounts to suit your bearers which will just need raising about 1", an easy job. From memory Vetus or Yanmar won't alter the engine mounts so you would have to remove the existing bearers and remake to suit - too much work I thought. I got a good deal ordering from LBS where you can see all the engines etc. I installed it myself and the local Beta engineer had to inspect my work to get the Warranty. I did fit a high rise exhaust as I was worried the standars was not high enough.
You will have to fit a new exhaust system throughout as, from memory the Thornycroft is 60mm Dia. and the Beta is 50mm Dia. exhaust hose. I also rerouted the exhaust outlet from under the transom to the transom so I could easily see the exhaust flow. I also fitted new sound insulation and a non-drip shaft seal.
If you need more info PM me.

If and when our T90 ever dies this'll be the place I'd go to.

The problem with a reconditioned BMC 1.5 is you will still have a very old engine design with spares coming from India of very questionable quality - I spent nearly £500 trying to sort out my engine before biting the bullet and grtting a new Beta. Never regretted the decision.
 
We ditched an old smoky ,unreliable BMC2.5 for a new Beta 60 and its been the best decision we have made .
Quieter , smoother ,reliable and the twin 120A alternators have made a hell of a difference to our charging requirements
The set-up provides serpentine belt drives and gone are the shredded belt residues that would accompany heavy charging on the old vee-belt setup
Beta panels are a bit poor ,if functional ,but as our boatbuilder used the components in our own custom panel, that was aminor issue
We had spent a lot of time, money and effort on the old engine , however its was just postponing the inevitable
The fuel consumption is remarkably good also
