small diesel advice

[nevillenolan]

I have a 25' keel boat and it's time I repowered.

I thought I'd go for a twin cylinder Kubota based engine, but a local marine mechanic says I should stick to the Yanmar 1GM10 or Volvo 2010, because they're genuine marine engines and can also be hand-started.

The Kubota appeals because it's 25kg lighter than the Volvo, with more horsepower. And it's fresh water cooled, where the 1GM10 is saltwater cooled.

Any thoughts?

Only the IGM is a 'genuine' marine diesel BUT it is sea water cooled - a distinct disadvantage. All other marine engines, including Volvo Penta are marinised Industrial Engines(except perhaps Sabb?...) The Volvo Penta is a marinised Perkins engine originally sold by Perkins as the Perama range but then all this small engine range for marinisation taken over by Volvo Penta.
Beta and Nanni are marinised Kubota engines. Vetus are Mitsubishi based.
Handstart VP2010? - double check on that!!
By the way, when did you last handstart your car engine? Not necessary nowadays.
The Beta has a good reputation, as has the Yanmar & Nanni.
Go for the Beta or similar but it'll depend

I've got a 1GM10 in a 25ft boat & would thoroughly recomend them. Simple but VERY reliable, lots of spares around (& also experience to fit/service them correctly (real reason for your mechanic's comments maybe?!)).
I know they're raw water cooled, but mine's almost 15 years old & (touch wood!) no problems. The only other 'con' is that they're not the quietest of engines being single-cylinder.

I might not hand start my car very often these days (difficult as it doesn't have a winding handle) but I do occasionally have to jump start, or recharge the battery before starting it.

Have you really never heard of a yachtsman not being able to start the engine using the starter motor?

I agree that it is rarely required these days - primarily because most people have engines that are too large to be hand started anyway - but in my case a full 50% of my battery capacity is dedicated to starting the engine.

Hi

Personally I would stick with the beta. The Vega club have now fitted over one hundred of tehse in the last three years to our 27' Sloops and never a problem. The company cares about its customers and their service is first rate. technically I would always go for a fresh water cooled, you have the extra 4HP over the Yanmar 1GM, easy to instal, spares are easy to obtain (Kubota based). I know I am a little biased but Beta have always been exceptional when dealing with the Albin Vega Club. Steve Birch

Have a 1GM10 in my Trappr 500, all 27ft 3inches of it, hand starts very easily,(mind you took a lot of practice) easy to maintain, lots of spares, great web forum and plenty of power. We drive a fixed 3 blade prop. Noisy, only when down below, but at least you can hear whats going on with it. Salt water cooled and the achiles heel is the exhaust elbow rots from inside out, but a known problem.

I have a 1GM 10 Very good engine but we have never been able to hand start from cold as the compression is so good and the fly wheel so small, from what I have heard and read this problem is quite well known so don`t rely on being able to hand starting one, fortunately I have never needed to!

The Bukh 10 is very much a genuine marine diesel and is a superb engine. Certainly can be hand started but is a heavily built motor precisely because it is raw water cooled. The one in my previous boat is still going strong with NO major repairs after 32 years!!! I reckon that's 'acceptabe' for a marine engine eh??

Actually, it's possibly a bit too heavy for a small boat and is not cheap, but if going for one of the other makes, I'd go for the Yanmar. As others have said, well built, reliable engines with a very wide spares network.

All IMHO of course!!

Good sailing!

What does your boat weigh? I've just exchanged the 1GM10 saildrives in my cat, weighing 5 tons odd...always underpowered, but very reliable. Stripping one down after 12 years use and I estimate 2500 hours in Greek waters, the waterways were almost completely silted up. but the motor would have kept going. I never ever had reason to hand start it, if you are that worried, carry a small spare sealed battery in a corner somewhere.
I put in 2gm20s because the feet were essentially the sameas the 1GMs. This has changed the character of the boat completely. No waiting for something to happen. She's very responsive and safe feeling. Also fresh water cooled etc etc. I eyed the Kubota clones and would have gone that way except for the different mounting feet, and less attractive saildrive. They are easier to service than the 2GM. However, the 2GM is to be replaced soon, by apparently an easier to service motor. The basic design isn't changing much...no direct injection or anything radical. I got a very good deal buying the older model.
Basically I'd recommend a larger motor than the 1GM. Another factor is the generator on the 1GM is 35 amps only whereas the larger motors have usually something like 55. Full charge on the 1GMs slowed them noticeably whereas the 2Gms don't falter. That made a good impression on me after all those low powered years!
Hope that helps...cheers....R

Sod all other advise, go beta 20hp, fresh water cooled, reliable and spares are cheap!.

~please excuse me but if I really posted me opinion of Volvo Kim would cancel my membership and send me a nasty email - we are not allowed to use the "F" word any more on these boards!

Almost forgot - the word following the "F" word begins with S and ends with T and the middle two letters are H and I or to put it another way ------ C. R A P.

Cant tell from profile,but if you're sailing with women or trying to persuade (convert) people to sailing go for indirect cooling with calorifier to supply hot water on tap.The concept of boiling a kettle to wash hair or dishes is a step too far for many people.
Mind you if you do that increase water tankage as the off switch on taps is another alien concept that potential converts find hard to grasp.
I've only been on a Kubota powered boat once; it started when asked and got us home in one piece.

I replaced my single cylinder Yanmar last year with a locally marinised Kubota - fresh water cooled and three cylinders and slightly lighter than the old SB12. It has very similar spacings / heights for mounts, and best of all, I now can buy spares from a tractor supply company, not a marine engineering firm.

Yanmar spares prices in Australia are comparable to Volvo - read that as steep! Kubota prices are extra-ordinarily low by comparison.

Thanks all.

Boat weighs about 1600kg and has a folding two-blade. Current engine 8HP max when new, a lot less now and no longer enough.

The Bukh DV10 has been discontinued.

About 6 years ago I got 13hp Beta (Kubota) for my 26 ft yacht. Now over 1100 hours on engine & never a problem. Most pleased with same. Small, quiet & simple. Give it proper routine maintenance & you wont be disappointed. You require any further onfo, just email me.
Rgds.

Thanks for this recommendation - useful, interesting, appreciated

Hi Extravert!

Yep! I was told they weren't available new anymore. Just thought he might have got a good one secondhand and saved some money over a new Beta/Yanmar. As I suspected, a Bukh 10 would probably be too heavy now that I've seen his boats displacement.

Cheers
