Hylas Discussion / Asymmetrical Spinnaker for H56 or H54 for sale
« Last post by Che Figata on September 30, 2022, 07:09:47 PM »
We have good news and bad news. The good news is that we are leaving on our long awaited circumnavigation in early 2023. This means we commissioned a new gennaker for the anticipated downwind sailing. The bad news is that we do not have a bottomless sail locker and must part with our lightly used Doyle G2 asymmetrical cruising spinnaker manufactured in 2014 for our Hylas 56.  Would work great with a H54 too! Dousing sock included and the color scheme is black, yellow and red.  Again, it is lightly used and was inspected in 2020 by the Doyle loft on City Island.  Asking $6,000 (US) or best offer.  All offers will be considered. The sail is currently onboard in Trinidad but can be delivered there in November or other locations between Trinidad and St Lucia as we make our way there for the start of our rally in February.  Please reach out if interested.  Contact info available through the member directory.

That earlier thread on Throttle Lag:  http://hylasyachts.org/index.php/topic,660.msg2169.html#msg2169

And 2 years on that engine still runs like a champ.

I was the original author of the 4JH3-DTE "Throttle lag" thread on here.  I just searched for it and it didn't come up.

In short, we tried EVERYTHING! including sending of the Bosch fuel injection pump for a rebuild.  It didn't solve the problem.  One agonizing year later I heard there were two NEW original fuel injection pumps left in the world and I bought one.  I solved the problem immediately!!  We have since sold the boat so I don't know how it has gone for the last two years.

Hi John,

On page 9 it looks like two versions exist a 2.45/2.45 and the 2.04/2.45. You only have the 2.04 ratio version? Everything I'm hearing from Hylas is saying 2.45 not the 2.04. Thanks for sending that manual by the way.

The yanmar manual shows the 4Jh3DTE engine KMH4A transmission should be a reduction ratio of 2.04 in forward and 2.45 in reverse.  You can find the specifications on page 9 of the manual.  The manual is at https://www.yanmar.com/marine/wp-content/uploads/2020/05/Operation-Manual_4JH3DTE-49961-202851.pdf

I had a new KMH4A transmission installed in True North in 2020 and it matches the specification form the manual.

Hi,

Yes, fuel pump and injection pump is new because we thought the same thing. The max people is rebuilt and nothing was broken on it. The mechanic wants to haul the boat and down pitch the prop to 18degree or even 16degree to get the rpms back.

The transmission they replaced my original from the factory transmission with is now a 2.04:1 ratio which is not the same as what was in the boat but they are saying it is fine. Seems wrong to me...

Jon,

I second checking the injector pump.  I had similar problems with my 4JH3DTE and rebuilding the injector pump resolved the problem.

You mentioned the fuel pump, however did you do anything with the injection pump?  We had a similar issue with RPMs several years ago with our 4JH3-DTE.  Most of the time the engine would shift into gear but would not increase rpms above idle.  However, sometimes it would increase rpms, usually after several bumps in and out of gear.  Turned out there was some corrosion in the injection pump rack/barrel area that would prevent the injection pump from increasing fuel flow.  Replaced the injection pump and all was well.

Check an old 2017 thread "Throttle lag on Hylas 54 4JH3-DTE". Also around that time there was discussion on clutch judder.
I suffered from both for a while and then they mysteriously dissapeared in 2018. Fingers crossed.
On the judder issue I believe there was a harmonic interaction between clutch and maxprop. Completely overhauled the maxprop and problem stopped. Co-incidence???
