<p>Due to recurring tendonitis I'm always looking for ways to do "normal" things without aggravating it by coming up with workarounds.

<p>This post concerns installing electric start on my 2016 Yamaha 8hp 2 stroke outboard.</p>
<p>Due to recurring tendonitis I'm always looking for ways to do "normal" things without aggravating it by coming up with workarounds. My outboard motor is in as new condition so replacing it is out of the question for now. Besides, when it does come time to replace, I'll be going all electric no doubt. </p>
<p>I contacted Yamaha in Australia and Japan and received the same answers. You cannot electric start my engine. This confused me as there was clearly provision for a starter motor mount on the engine block so I delved a little deeper. The key was to find a flywheel with ring gear and in about five minutes online I found several second hand listings in the USA for the 6 and 8 hp 2 stroke models. I ordered one. Next was the starter motor which Yamaha DID want to sell me (it's generic I think) for $350 AU. Being a little more than I thought it was worth I kept looking around. I found an AliExpress seller who sells electric start kits for a range of motors. I asked about the 8hp options and was told again, no, it can't be done. I took a gamble and bought a kit that suited the 9.9 and 15hp 2 strokes without flywheel for $180AU.</p>
<p>Everything arrived two months later and was installed in a day. I had my local Yamaha dealer fit the flywheel in case there was a problem but there wasn't.</p>
<p></p>
<p>So, I'm now the happy owner of a rare electric start AND pull start 2016 Yamaha 8hp 2 stroke outboard and the perfect auxiliary for my Tiki26. I'll link a short video below.</p>
<p>Hope this helps someone else.</p>

<p> We are approaching the point where going all electric will make sense..........at least for a "voyager". The cost in inconvenience of maintaining a gas or diesel engine is at the point relative to batteries and solar panels, etc that unless you are married to a schedule, or impatient it makes sense. Batteries are expensive.... solar panels are "cheap". But it means that you can run an electric galley, a water maker, and electric propulsion (in port). Imagine eliminating gas or diesel, propane or alcohol. Eliminating the cost and weight. Eliminating pumps, cans, tanks, lines, filters, dirty fuel issues, different standards for propane bottle fittings, having to have a vented compartment, eliminating the danger of explosion, etc.....Having reliable refrigeration, fresh water that you KNOW is good quality and don't have to haul out on a dinghy or take a slip to get......... Being able to take a fresh water shower in the cockpit without having to worry about using precious limited water......... It's a WIN WIN WIN situation as far as I can see. We can purchase lithium batteries economically enough that it would be foolish to use anything else when you factor in REAL usable capacity.......not to mention cycle life. Regenerative electric outboards are available and not expensive compared to ICE outboards.</p>
<p></p>
<p> My personal dream that I'm hoping to achieve is a "small" catamaran to go world voyaging in as a long term (many years) live aboard. Because weight is such a huge factor in multihulls, everything points toward electric. I want a level of independence that would previously have called for a larger boat....but I don't want a big boat....the optimal size would be the Tangeroa , which with aggressive weight control I could equip with a decent "workshop" in one hull, and a decent complement of tools, spares, and materials. It would have a biplane junk rig, and use one or two outboards. A pod or the "half pod" I described recently would be a non-negotiable. Everything would be geared to "max independence". It would have a refrigerator / freezer in some form, and a vacuum sealing system for foods, and some sort of dehydrator... perhaps along the lines of "sailing the farm". Cooking would be electric with a small propane backup, and direct solar options.</p>
<p> The big challenge is electric and salt water........ inherently incompatible. The problem is connections...That's where electrolysis happens. Interestingly lanolin seems to be about the best protection from this......at least ashore. You can buy all kinds of fancy products, but ordinary lanolin from sheep will stop corrosion / electrolysis better than any of them (really). </p>
<p></p>
<p> I dream of slipping the surly bonds of earth, and dancing the ocean on laughter silvered wings.... Playing fast and loose with the poetic words of John Magee....... As a pilot this beautiful work has been an inspiration flying ultralights, trikes, hang gliders, ordinary aircraft, and even a jet. The beauty and joy of sailing falls into the same joyous realm... at least for me.</p>

<p>Oh! I have slipped the surly bonds of earth,<br/>And danced the skies on laughter-silvered wings;<br/>Sunward I've climbed, and joined the tumbling mirth<br/>Of sun-split clouds, --and done a hundred things<br/>You have not dreamed of --Wheeled and soared and swung<br/>High in the sunlit silence. Hov'ring there<br/>I've chased the shouting wind along, and flung<br/>My eager craft through footless halls of air...<br/>Up, up the long, delirious, burning blue<br/>I've topped the wind-swept heights with easy grace<br/>Where never lark or even eagle flew --<br/>And, while with silent lifting mind I've trod<br/>The high untrespassed sanctity of space,<br/>Put out my hand, and touched the face of God.</p> Tiki 38 Outboard tilttag:wharrambuilders.ning.com,2021-09-24:2195841:Topic:2901972021-09-24T22:24:07.745ZGuy Elleryhttp://wharrambuilders.ning.com/profile/GuyEllery
<p>Hi all, i have only recently purchased my boat and was wondering how many people tilt their Yamaha 9.9s, i find it difficult and wondering if most people just leave it permanently positioned in the vertical position, raising and lowing the sled only.</p>
<p>Any personal experiences would be appreciated.</p>

<p>We are thinking of replacing our Yamaha 9.9s with Suzuki 20s as the Suzuki has fuel injection rather than a carburetor. We know people who have used the suzuki on their tenders and are very satisfied but were hoping that someone here would have had experience of using them on a cat.</p>

<p>I just launched my Tiki 31 Maija-Liisa, and on the first sail I was met by a policeman on a water scooter. He congratulated me for the big occasion; it remained a mystery to me how he had known that this very day I was launhcing the boat! Obviously I am living in a small town, where the news spread quite rapidly.<br/><br/>What the policeman said next, was another surprise. He asked for the registration of the boat. In the process on building and launching I had completely forgotten about it. In Finland I have to register any boat longer than 5 meters.</p>
<p></p>
<p>The policeman was very kind and did not fine me or do anything else unpleasant. He just told me to hurry up with the registration. This is what I am doing now.</p>
<p></p>
<p>In the registration form they ask for the maximum power capacity of the boat engine. I have at the moment a small old Volvo Penta 3.6 hp engine, but I am planning to get something in the range of 10 hp, which obviously is about the size used on Tiki31 or Tiki30. But I'd like to register maybe a bit higher figure, just in case something comes up, and I'd find a somewhat more powerful engine (it is not easy to find a used engine with a long enough shaft!).</p>
<p>So my question is: has anyone installed a more powerful engine than a 10 hp on Tiki31? Or what is your opinion about this? I'd appreciate your help, because I think I must hurry with the registration: my Tiki is the only catamaran around here, and I am pretty sure the police will renew their visit in the near future, just out of pure curiosity!</p>

<p>Hi,</p>
<p>We are building a Tiki 38 and are thinking of usin g 2 small inboard diesel engines (12HP each) with a slanted long shaft that (not Z drive).</p>
<p>Does anybody have any experience with this solution and can also recommend which make to choose?</p>

<p>We have lots of posts here about assorted engines being employed on different boats, but we have little relative data to help an owner get the proper engine for their boat, in the conditions they're likely to sail in. For example, a Tiki26 that navigates coastal rivers and associated tides is likely to have more engine than required for navigating an inland lake. </p>

<p>We had a protracted problem with our main engine this year. Fortunately we had just bought a engine for the dinghy and were able to use it to move Mango (T30); however, we had bought a short shaft engine for the dinghy, which is normal, but it cavitated badly on Mango if there was a chop so we would have been better of buying a long shaft for the dingy to give us a good back up engine for Mango and put up with the inconvenience on the dinghy of a deeper prop. </p>
