Alan and Bill and others,
I hoped to be right behind you guys and in SouthPort today, but I’m berthed
at Deaton in Oriental and not likely to be leaving before next week. I
stopped in on Tuesday to have a couple of minor problems checked out. The
tachometer was going crazy again. The last time that happened the whole
instrument panel (Yanmar/VDO piece of junk) failed. Also, I was getting
slightly excessive engine vibration above 2,000 RPM. I’ve had work done by
Deaton in the past and was very satisfied with the work and the staff. I
didn’t consider the instrument and vibration issues as critical, but I
wanted those issues addressed by a yard I trusted.
On Wednesday, Eric the service manager and most experienced mechanic, came
on board to review the issues before prescribing some action. When he
asked me to start the engine and put it in gear so he could evaluate the
vibration, I was astounded to hear the old gear backlash that resulted in a
transmission rebuild last winter. That backlash was reduced to an
acceptable level by replacing the defective damper plate. Suddenly I have
the defective damper plate symptom back again.
So I’m stuck here for at least a few days until it is determined the damper
plate is bad (this is one of those supposedly robust R&D plates, not the
spring-loaded plate originally supplied by Mack Boring). I hate to go to
the expense and time of removing the transmission to inspect the damper
plate, but I also don’t want the expense of another transmission rebuild
(or replacement).
So my southbound voyage will temporarily (I hope) stop here in the Neuse
River. Assuming these problems will be resolved in the next week or so I
will move Sarah back to New Bern where she spent most of 2009/2010 while I
fly to LA for the family Thanksgiving get together. When I return I hope
to again be underway south by Dec 1.Regards,
John Stevenson

John – Alan & I read your email over dinner here in Georgetown, SC. So
sorry to hear about your troubles; at least you’re in good hands with John
Deaton and Eric.
Its been a tough season weather wise to get offshore! We are hoping for
Sunday out of Charleston. Although the winds are predicted southerly, at
least they’ll be light.
All the best, BILL~~~ ~ (_~~ (_~ ~ ~ fair winds ~ ~ (_

John,
Its odd that you have problems with your Yanmar instrument panel. I’ve had no issues with mine, and my yacht club has two launches with much the same engine and panel (4JH3TE) and have no issues. The club launches are in continual service for 7 months each year. That’s over 2000 hrs/year. I’m also not aware of any damper plate issues either. I picked this engine because the club has such good luck with them.I have very little vibration all the way up to over 3000 RPM. Doors don’t rattle and there’s no vibration when seated in the cockpit. I can feel vibration when standing on the sole in the aft cabin, but I think this is from prop-wash.

Rich,
This instrument panel problem may be due to my going with the standard
Yanmar 80A alternator rather than the Balmar-type you have. I think the
alternator is generating some spikes or other problems for the board in the
panel. The panel is a flimsy affair, which I mistakenly had installed on
the bridge deck, where the Westerbecke panel was located. The Yanmar panel
should not be placed in a high traffic location such as I have done.The vibration I think is just an alignment problem.
The original damper plate problem (IMO) was a DOA part provided by Mack
Boring. If I’ve had another damper plate failure (won’t know until the
transmission is removed), I’ll be looking for an explanation. The
replacement damper plate, provided by Mack Boring at my cost, is one of the
R&D-type plates, not the spring loaded plate originally supplied.See: http://www.svsarah.com/Sarah/ewVelvetDriveFailure.html

John Stevenson

John,
you’ll have to let me know what happened to the damper. As
you know I have the same damper in my W58. I have been very pleased so
far. No noise what so ever.
BUT…..
We were all waiting for the
the 4 o’clock opening of the Ben Sawyer bridge just before Charleston.
You know how all the boats mill around waiting…. I snagged a crab pot
and before I could react, it jammed the prop shaft up tight. It pulled
the shaft right out the coupling. TowBoatUS was there in 20 minutes and
towed me into the slip I had already reserved at the Maritime Center….
and I was only an hour and 15 minutes later than if I had motored in
myself.
. NO CHARGE. It pays to have UnLimited Gold towing insurance from BoatUS.

On my way down on a delivery in October we got to the Ben Sawyer bridge at
1603. Dammit, we had to wait for 2 hours! I hate that bridge! Sorry
about the trap thing. Unlimited would have done as well, though. Gold
allows tows dock to dock. It’s one of my careers here – Tow Boat U.S.Bob

I was lucky that it was a holiday and it opened every hour between 4 and 6.
Hopefully I can get a diver tomorrow to unwrap this thing. I think I am still dragging the pot with me. Some fisherman is gonna be disappointed when he goes to retrieve his gear. Although… he should not have put it so close or in the channel.
Geez…. even when your paying attention sh*t happens.

Sorry to hear about your travails. I hope no damage was done – I picked up
a string of pots somehow south of Pidgeon Key and I only found out because
I was under full press of sail in 20-25 kts wind and only going 3 kts.
When I looked back it was like the barrel in ‘Jaws’, except it was traps.
Finally because my prop spins it actually twisted the line until it
parted… Then all of a sudden I was going 7.5 kts!Bob
