Our New Engine!

[TOM]

Apologies, but this thread is about nothing realley except to welcome our new motor.We are that excited that we just have to tell everyone.She goes in on Monday and all going well we should be back in the water on Friday to continue our journey. Mechanic has given us a rough quote of $3000 AUD for instal ,this does not include the new 3 inch exhaust or crane hire.He comes highly recomended and is very honest with his prices{at least thats what we have been told } .Guess we will wait and see just how much the whole thing ends up cutting into our cruising kitty,but we know we have made the right decision ,our journey will just be that much easier with a brand new engine.

Tom,

Many of us hairy-chested sailors have had to beat against the tide, into a narrow entrance rock-strewn harbour, in a full gale--- IN OUR DREAMS.
Knowing that engine will start when you hit the key, is at that time, more reassuring than the most weatherly of rigs. Have fun!!

Ahh the joy of a new member to the family. Soon you will be enjoying the pitter patter of little pistons under the cockpit sole. Keep the little fellow warm and well fed!

Congrads, a great engine which should give you years of service.

I've just put the first hundred hours on that engine's twin. You'll love it, other than for that alternator. I switched mine out for a Balmar and haven't looked back.

[David M]

Nice!

Which Yanmar is it? Specs?

[TOM]

Hi David , it is a 4JH4-TE Yanmar 75hp turbo charged to 3200rpm . I was lucky enough to get the last 2008 one at the 2008 price ,a saving of nearly $3000.It is the exact same as the 2009 model . Bash good to hear you are happy with the motor .We are hopeing it will be much quieter then our old Tractor motor!. What was the problem with the alternator?why did you change to a Balmar

[David M]

Balmars generate more power than the stock alternators. The advantage can be faster charging times and the ability to draw more power with your DC system. They are also beefier alternators meaning less prone to failure. Balmar can tell you which of their alternators will work with which engines.

Yanmar does have a high output alternator as a option... but the stock is not.
Tom, since I am about to spend a lot of money rebuilding my perkins or upgrading to the next size perkin... about how much did you pay for that yanmar ?
Less than 10K
Less than 12 K
less than 14K
or more than 14K....

thanks
bob

Hi Bob,

The engine cost us $17500 Aussie dollars about $14500 us dollars.We saved $3000 as it was a 2008 plate . Yanmar have had significent price increases in Australia this year due to our dollar this may not be the case where you are. We could have bought a Volvo ,Nanni or Vetus cheaper but At the end of the day a YANMAR will always get you a better resale value when you come to sell the boat .

Good looking engine.
Tom
How are you handling the power take off to your refrigeration system?

[bobfnbw]

Thanks tom.
My 4-108 rebuild is going to cost around 8K so I guess I will stick with that.

You'll find the TE engines to be much more quiet than normally aspirated diesels. I didn't originally want a turbo, but all the larger diesels have to be turbocharged nowdays to meet clean air standards, so I didn't have a choice. Having owned this one I'll never go back. The turbo doesn't have that rattle that older diesels had.

As far as the OEM alternator--which I believe is made by Hitachi--I never had a problem with it because it was never installed on my boat. My previous boat had a smaller Yanmar, and I just wasn't impressed with the stock Hitachi alternator output on that engine. I opted not to install a diesel generator on this boat, so having a quality high-output alternator to complement our solar and wind power systems made a bunch of sense. And there seems to be a near-consensus among the cruising community that Balmars perform best, especially in hot conditions.

It is fairly easy to make up a bracket to fit an extra alternator, although you'll need a dual engine pulley. That way you have a built in backup if an alternator fails, plus extra charging capacity. Before you make any mods though, check that you are not voiding the warranty on your new engine! Regards, Richard.

Pretty engine! Congratulations. My experience with Yanmars has been nothing but good. Starts the first revolution with no glow plugs or air pre heat.
