August 20, 2018 at 8:49 am Trying to get better pictures but for now this is what I have.
5 RepliesSeptember 4, 2018 at 6:15 pm I have it and am able to run it now, but prop seems too big maybe. I had a 2:1 before, was kind of hoping it was a 1.75:1 and I’d be ok.Last Post by:

Low pressure in ZF 63A
This topic has 6 replies, has 3 voices, and was last updated by
6 years ago August 18, 2018 at 5:02 pm Hi all, I would really appreciate some advice on a new problem. I have a Caribbean (Bertram) 32 with twin 6BT and ZF 63A transmissions. Several months ago I had a shaft seal replaced on the port gearbox, replacing the fluid with Shell Spirax ATF. The boat hasnāt been used since then until yesterday. The transmission pressure was low and flickering but it would go in to both forward and reverse ok though I suspect at times I had some slippage.. T…
6 RepliesAugust 26, 2018 at 4:44 am I see you have a VDO transmission sender listed as 28 bar/400psi. Would this be a suitable replacement for a 25 bar 360 psi VDO sender in the ZF 63a of mine? Thanks NckLast Post by:

ZF Hurth Model HSW 800 A2 – 2.0 Help me learn.
This topic has 4 replies, has 2 voices, and was last updated by
6 years ago July 26, 2018 at 3:12 pm Finally found the tag on one of my transmissions (gear boxes). A Google search didn’t turn up more than a simple chart showing gear ratio, power and torque specs. I’d like to get a better feel for the maintenance routine for them. A operator/maintenance/repair manual would be nice. Looks like this is an older model that has been replaced by the ZF 80A Thanks in advance. Paul Changes in L'Attitudes 1999 Maxum 4100 SCA Twin Cummins …

After running 1/2 hour port side runs 130 degrees f the starboard runs 165 degrees f. some thoughts are sice one side is counter rotation it will run hotter??? I have owned the boat since new 2005, Searay 390 dancer with cummins 370 qsb diesels. I have never noticed this. Presures at 2400 rpm are the same side to side 365 psi. When at 850 …

6 years ago June 18, 2018 at 1:37 pm I have noticed lately that my starboard clutch is slow to engage reverse and feels as though itĀ“s slipping or not engaging completely. IĀ“ve tried disconnecting the cables and shifting the selector manually at the clutch and get the same result. IĀ“ve also checked and the filter screen which was clean and changed the oil (40wt) and that did not make any difference either. Pulled the selector and replace the o-ring, reinstalled and double checked t…
2 RepliesJuly 10, 2018 at 9:14 am Tony, I’m having trouble locating a replacement filter screen for the MG507. When servicing I accidentally stepped on it and it crushed. I straightened it out as best i can but I would like to replace it with a new one. I would also like to replace the cover with the o-ring as the previous owner stripped out the threads used to insert the bolt to remove it. Will the screen for the MG5075 work for the MG507?

July 8, 2018 at 3:21 pm A few days ago, I was coming into the marina’s channel to get to my slip. All was fine till I wanted to turn to starboard. I put the port transmission into reverse from forward and nothing happened. Neutral. I put it back into forward and it stayed in neutral. After some piling bumping and help from the dock crew, I got into the slip. Removed shift cable from transmission and shifted manually; stayed in neutral. Transmission fluid is clean…

ZF 325 Low Pressure – Slow response

6 years ago June 12, 2018 at 4:24 am ZF 325-1 gears. 2006 boat, new to me. Electronic controls and trolling valves. Problem on the starboard gear. Transmission pressure normal at start up, 343 PSI each gear. Putting the starboard in gear response is slow. 2-3 seconds or so from putting in gear to gear activating. Pressure drops to below 20 PSI and wont come all the way back up. No oil in bilge. No oil going out the pipe. Recently had an issue on same gear cooler leaking at fitt…

6 years ago May 28, 2018 at 9:35 am Continuing to learn the boat … PO paperwork stack has a ZF Marine HSW/HSWE manual (models ranging from 250A through 800 V2).

ZF 325 1A Valve Block Leak

May 23, 2018 at 6:11 pm Hello all. I just joined this forum but have been familiar with Seaboard with ordering parts for my QSM 11’s for a while. I have a small leak which appears to be at the front plate of the Valve Block. Thanks in advance for any advise or tips on getting this fixed. Is there an “O” ring kit?
2 RepliesMay 23, 2018 at 7:33 pm Hi Tony, Thanks for the quick response. Unfortunately, I’m now in NY and the boat is in Florida and I wont get back to her until June or July. Attached is a similiar photo from another post where I pointed to where I believe the leak is coming from. I put a piece of an oil pad and slipped it under the end cap and it became oily after running. I guess it’s possible the leak is from under the valve block?Last Post by:

ZF Marine IRM280PL gear rattle / chatter
This topic has 1 reply, has 2 voices, and was last updated by
6 years ago April 17, 2018 at 12:34 pm I have a ZE Marine model IRM280PL transmission coupled to a Cummins 6BTA5.9M3 330 hp engine in my 1999 Nordic Tug 37 with currently just over 3000 hours on them. Ever since I purchased the boat at 2010 hours, I heard the gear rattle/chatter when at idle speed and the transmission in gear (only at that time). A slight increase in engine speed would eliminate the rattle/chatter (similar result to what was posted on your website). Last year I ch…
1 ReplyApril 20, 2018 at 6:15 am If you are getting gear rattle or clatter above an idle, and especially above 1000 RPM, your torsional coupling is most likely ready to fail, or has completely lost its “damping qualities”, or both..

Closest current model match to ZF Marine model IRM280PL

6 years ago April 17, 2018 at 12:48 pm What is the closest ZF Transmission model to a 1999 ZF Marine model IRM280PL transmission? I am interested in what posted tips and suggestions would be applicable. In particular, the comments about measuring the transmission oil level. My transmission OM states to measure the transmission oil level when the engine is running and in neutral and idle speed. Once the dipstick is removed, oil spurts out aggressively from the opening. I think th…

There are also some physical internal & external changes, but if something did happened to yours, the change out is easy.. As to oil–A quality SAE HD 30 W meets the spec. Some 15W-40 also meet the spec. Oil level & checking–The manual is quite confusing on and if you ask an employee at ZF, you will not get a solid an…Last Post by:

6 years ago April 5, 2018 at 3:51 pm Hello all, My transmission gage on my ZF 220A only reads when the trans is shifted into reverse. The starboard trans works in forward perfect.

November 5, 2017 at 5:14 pm Just bought a workboat with an older JWAC 6BTA, 250.

Presently have a drive saver in line, so there is an 1.5″ or so extra length available if needed. David

Re-powered with QSM11 remanās with ZF 325ā1 A transmissions. These are electric shift throttles and trans run by a Gleninning system with trolling valves.

2 RepliesJanuary 26, 2018 at 3:39 am Well Iām a little embarrassed, at least I donāt have a gear problem. I discovered that this boat has two different transmission controllers.

The EB 30 controller does not show full operating pressure until put in gear and given some rpm. The EB 31 controller shows full operatin…Last Post by:

Shift delay
This topic has 4 replies, has 3 voices, and was last updated by
7 years ago December 21, 2017 at 6:42 pm My ZF285A transmission has a shift delay programmable through the Glendinning EEC3 control with a range of 0-2.5 seconds with a default of 1.0seconds. Nothing wrong with the transmissions. Things that make me go hmmm… What is the purpose of this delay? Why would one be inclined to change from the default of 1.0seconds and whatās the reason 1.0 seconds is the default. Phil

For those that have Glendinning controls, Rick is a wealth of knowledge and a true gentleman who solved this mystery. There are two delays, both designed as preventative measures. For those that have never driven electronic shift/throttles they are silky smooth and itās easy to bump them in a moving boat. And yes there are friction adjustments for both detention and movement, but even s…Last Post by:
