1. Please do not reply to old topics or hijack existing topics. Old topics of a technical nature are like a library book, Please do not write in them.

2. Old topics should be considered archives and used for reference only. Please do not reply to them.

3. Do not take over someone elseís topic (aka hijack) with your own question, even if it is similar. If you have a question that has not been covered to your satisfaction in the archives, it is always best to start a new topic of your own.

4. If you have a question for the original poster (OP) and the topic is over 30 days old, send the OP a PM, he may not even visit the forums any longer, or may not notice your question in the old topic.

5. By starting your own topic, you will receive the maximum number of views by forum helpers that may not even notice your question when itís posted at the end of someone elseís topic. And those answers will be specific to your particular issue.

6. Please do not post to topics that have been inactive for more than 3 months unless you are the original poster. We have very active forums and any topic that remains inactive for that long should be considered "dead". It is especially confusing when there is an entirely new question posted to an old topic.

7. Posting at the end of any topic is considered to be hijacking the original posters topic which in turn subjects the topic to be closed if it continues to happen thus not making it fair to the original poster in the future had for some reason he/she needed to return for additional information or provide an update of the problem solved which is always welcomed within a reasonable amount of time frame.

8. Please note that you should see a red banner pop up near the bottom of each inactive topic asking you not to reply to old topics. The Red banner will read: Please note this topic has been inactive for 90 days. For the best results, please start a new topic.

  • Yanmar Diesel outboards- What are they like and Where can I get one?

    The gas useage of my 50hp merc is beginning to wear a bit thin now... it's close to £4 per gallon for petrol in the UK so I'm spending £20 per hour running at WOT.I'm seriously thinking about going over to a yanmar d27 or d36 diesel outboard. Speed aint really an issue when the price of red diesel here is between half and a quarter of that of petrol and they apparently burn just over 1.5gph. The only problem is I can't find anyone who's ever used or worked on one-or that sells them in the UK. Are they all that yanmar claim? I'm kinda dubious about aluminium blocks on diesel motors.

    hello I did a search and saw a dealer in the UK. I have never worked on one but have seen a few on some yaht dingies. they seem to work well. sound and smell funny but the owner loved it. aluminium block diesels are not new at all.

      But what if it breaks? Who's going to fix it and where are you going to get parts? How long does it take to order parts that aren't in stock? Unless there's a strong dealer base, I'd bite the bullet and stay with what you have. Maybe go with a smaller 4-stroke if speed isn't a factor.
      Hey, Have you seen? They make Really Cool life preservers nowadays.
      So "Looking Dorky" is no longer an excuse for not wearing one.

        Re: Yanmar Diesel outboards- What are they like and Where can I get one?

        Thanks rodbolt!The thing is, even if I buy a smaller 4-stroke it's still going to cost a fortune in gas per mile-as an example, pump gas here is 80p/liter,equivalent of about $1.40.RED (agricultural untaxed) diesel which is perfectly legal for use in boats is between 19p and 40p a liter-and I'll have enough in my tanks at 10-12 knots to go fishing all week for about £20.The dealerbase is one reason I'm a bit wary-but then I'm 40 miles from the nearest merc dealer too (and 35 from any other!) so as long as there IS a dealer then I'll be happy-it costs me more to drive to any dealer than to mail-order anyway. Besides, being a diesel it's going to be that much more reliable and I don't have to worry about gas going stale in the tanks.I still can't find that dealer though-any clues?

            I saw a little inboard boat in wooden boat magazine.It was about 16 ft and was designed to run at displacement speeds 6-8 mph.I think it used an 8 or 16 hp Yanmar deisel inboard designed to run on reclaimed vegatable oil.And to top it off it got something like 28 miles per gallon.You can do something like that with a hull like a sailboat(not fixed keel) and a small outboard.Displacement hulls are the most efficient design but are most efficient at true displacement speeds.usually around 6 mph.If you are thinking about a deisel outboard how about an electric outboard(not trolling motor)Do a search for electric outboard.They will actually plane a small boat.Ill bet they are a lot easier to maintain than a diesel and a heck of a lot quieter and no smell.

              i'm not sure but I think you guys may have got the wrong end of the stick-the d27 and d36 are quite large (physically) engines and 27 and 36 hp respectively-as in, just enough power to get my 16' cabin boat to the plane with the 36hp. They are also quite heavy-the d27 weighs 110kg so as heavy if not more so than my 50hp merc.They'd sink a yacht dinghy! What I really want (utopia here I come) is to be able to go fishing 15-20 miles out and it not to cost a fortune every time. I can't carry enough batteries to do that with an electric outboard!From what I've read the yanmar outboards are ideal for what I want - diesel being at 1/4 price of petrol here and the fuel consumption being around half that of a petrol too but I've never actually seen one in use and I'm dubious about buying something without knowing something about them 1st.The only ones I've EVER heard about have been for sale on ebay, and they've all been seized or trashed. In my mind that could mean one of 2 things- either no-one ever sells a running one because they are so good, or that there's hardly any around and they break!As for running at displacement speeds i can well believe it-I recall in my youth my father crossing the English channel (Poole to Cherbourg-60ish miles) in the flat calm with no wind in our 30 foot sailing boat on 3 gallons of diesel at 4 knots...that was with a 12hp twin cylinder inboard bukh.

                I've just found one that works for sale on ebay! Unfortunately it's part of a boat package though so won't be buying it. Here it is for anyone interested. http://cgi.ebay.co.uk/ws/eBayISAPI.d...sPageName=WDVW

                  Yanmar has been making small diesels for eons. They have a very good reputation in the industrial world.I wouldn't be afraid of one.

                      For anyone who's interested- I got hold of a yanmar outboard dealer in the end. Spares are still available but the outboards are out of production though they WILL make them...at a cost of £13500 for a 36hp!!!!!!!!!!Thats $25000! No wonder they aint making them anymore! I think maybe I'll give up on the idea unless one comes my way 2nd hand.

                        Sounds like they're making "one offs" out of those spare parts.Will they send you a kit, and you build it yourself?

                          Unfortunately the "dealer" wouldn't give me that option- I did ask. I wonder if it's possible to convert a 4-stroke to LPG instead...

                            I have after a lot of searching managed to find a yanmar D27 to put on my canal/river cruiser in place of a 25hp Mariner which also drank petrol like it was going out of fashion .... if there is enough interest i will write regular updates on all aspects of performance and maintenance of the d27 as first hand information seems so rare ... so if you are interested please let me know .... I am located in the east midlands on the river trent .... and before you ask Nos4r2 no it is not for sale! and it took 2 years to find the right one
