Mobile Marine Engineering on small water craft.
Following Me Darren Crouch while I go about my days work as a Mobile Marine Engineer either on site or at the workbench, I provide onsite repairs and servicing to small craft. We moved recently to Boston in Lincolnshire, this is a great new chapter for us. I really love my job and the people I get to meet; they are as varied as the boats and locations. No boat is the same nor the persons I work for, every situation is bespoke. It is a tough job and there is currently no hand book to work from.
The aim of this channel is to help educate and bridge the gap between engineers and the public whom have an interest in knowing more about the equipment they depend on.
Any advice or suggestions here are taken at your own risk, no liability for your own actions can be taken.
If in doubt seek professional advice either with us directly or independently.
Thank you.

Inspection service of the main engine and drive system on River a Thames motor boat.
appreciate it. just aquired a 01 master craft with this transmission. need to learm how to service it.
Change the oil regularly and use only mineral. ATF unless the manual states if differently.
Excellent explanation and well shot video and audio. . thanks
Such a great channel - really clear explanations. Cheers!
Than for that, its appreciated.
Great video! I learned a lot about my twindisc tmc260 which is practically the same I think.
Great video, thanks for sharing. Being relatively new to owning my own boat I've always wondered what the set up was inside the bell housing - now I know! I have a Nanni 4.190HE engine with a PRM 160D2 gearbox, and sometimes I get a "hard' clunking noise" when changing from forward to reverse, even though I take my time moving the lever (i.e I don't slam it into reverse). Could this be a sign that the drive plate is wearing out?
Check the Idle speed. It should beas low as designed. To high RPM will cause this.
@@dhcrouchmarineltd3049 hello again, I've checked the PRM160D manual and it recommends approx 1000rpm before moving from forward to reverse, and mine engine ticks over between 800 - 900rpm. Any other recommendations on what to look at next? Regards,
Does it vibrate?
Thank you Darren very interesting . I'm wondering.. can silt go into the flutes of the bearings and find it's way into the drip less seal area ? And then would this need cleaning out ?
Yes of course, shallow waters allowing crud will just make a grinding paste. Like anything an ideal environment is desired yet the world is anything but. I have seen excessive calcium build up finding its way in and that stuff is evil.
@@dhcrouchmarineltd3049 mine squealed the other day and I wondered if that might be what had happened

Fantastic 👏👏👏👏👏👏👏👏👏
Very nice video. Nice and complete info but I still have a question for you. I'm on a sailboat with a Perkins 4.236 and have just had my nozzles done but I've since sailed on from the island where I had this done and I am now in a very "middle-of-nowhere" sort of place. Now I see that two of the injectors are leaking from the adjuster nut cap. I am pretty sure the shop did not replace the copper sealing washers on those. After watching your video, it seems I can attempt to fix this in the field. My question to you: Am I correct that there should be no harm done to the injector or the "pop" setting if I remove the injectors and torque down on the adjuster nut cap to 50psi as you did in the video in hopes to create a seal? I remember the man at the injector shop being very clear (although in a language I speak poorly!), not to touch the torque on the caps or the nozzle nut...but I think I trust you more.🙂
The caps/nuts are just a loose thread and bite into the copper. Provided you dont drag the setting screw back you'll be fine. Use a blow torch to reanneal the copper or better still replace them. Check the faces of each surface as this stuff is getting very old. You may have to lap out some pitting. Use a new oil stone very fine if you need. Be sure its flat hence new.
What are the odds that I could drag the set screw as you stated, assuming I'm just setting the adjuster nut cap to 50psi? Is this a real risk, and thus proper protocol to recheck all of the pop settings after the adjuster nut cap has been torqued down?
@@strongmonty Its a screw. Probably unlikely but vey possible.
how did you change the timing?
Its a CAV pump. Just loosen the body nuts to the engine and slaken the injection hoses and twist it one way or another advance or retard its timing. There is more to it but thats basically it.
Hi, we have this gearbox and we hear a noticeable clunk when selecting forward gear from neutral. The oil level is fine and the ATF oil has been replaced during the time we have had it. At first I suspected a drive plate issue but if it only happens selecting fwd I am now doubting my initial thoughts. Any suggestions? Thanks in anticipation.
Loud clunking, depends how loud. If the drive plate is trashed and someone over advanced the idle then the box will thump into gear. The idle needs to be low for a smooth engagement. That being said if the cone has any burrs itll bind a bit.
Great completion! Was the exhaust silencer a particular type/brand?
Was manufactured by the Hayden's I believe. It allowed cleaning and access into the wadding.
I gave up buying fuel from boat yards, I now only buy from roadside filling stations, the fuel is clean, water free (probably because its not been hanging around in a tank next to the river!....cured all my fueling issues. Yes its a pain filling with jerry cans but better than stripping down the injection system every other season.
What engine do you have? Some can use. HVO is now quite handy to try!
Dual mass flywheels are used to reduce torque vibration into the gearbox. Should not be needed on a boat.
Agreed.
Look at the Fiat JTD twin cam diesels. Hydraulic tappets and the timing belt versions are easy to work on.
I bought a pair of motors that have the Hurth model HSW 450 A2-2,0 ser n 22 15223 A they have been sitting for years from what I was told they were took out of a boat after 20 to 40 hours run time and replaced because the owner wanted more power what do I need to do to make sure there ready to be used again I have manuals on them but I’m wondering about the seals or gaskets effect of stagnant fluid or no fluid on them
If I was called to inspect them I would drain the fluid (if any) and check inside with an endoscope. Try to gauge the state of play inside each box. If they are not on the engine then check the seals isnt hard. If they are crispy then definitely change them. All depends whats found. Do they spin by hand, engage each direction and see if there is any binding. Hope that helps a little
Thankyou there still on the motor I just got them I was planning on rebuilding the motors this helps me out it’s really hard to find any information on these transmissions I have a original service manual for them but that don’t cover sitting in a barn for 20 plus years and I had no knowledge of inner working until I found your video many thanks for sharing your experience and knowledge I can use all the help I can get this is my first complete boat rebuild it’s a 79 pen yan 24 footer and the only thing it has going for it is a fiberglass hull
@@patrickg.6438 bear in mind what ever transmission you use will define the physical installation. Changing that later to suit another brand will cause you a head ache. Be cautious and work with equipment you can get parts support easily. Thats my advice anyway.
What would you suggest I do should I sell them and buy new to me ? the motor in it now is a Chrysler 240 that was run in salt water completely ruined the Chevy 350 vortecs multi port fuel injection I have now are 89 threw 94 models can’t find any more info than that on them but they are very buildable motors I have to gut the hole boat and was going to do some reinforcement with carbon fiber so mounting should not be a problem I got this to have a project with my grandkids who lost both mother and father a few years back and would like to pass it down to them what would you suggest I do and how would I reseal the shaft where it passes threw the hull for the prop and I was thinking about saving up to buy a Sharrow prop do you have any comments on that type of prop
Yes full of ATF looks like it was pored just today and looks brand new inside we are going to remove them this weekend sorry had to wait for the kids to help all or none do you have a P account would like to buy you a drink
I had one in a fiesta van, good economy £10 per 100 miles back in the day
Yes my father had the same. Swore by it.
Love your videos? Have you have come across a Leyland thornycoft 230? Have one of these in boat in Australia.
No not yet as far as I am aware.

What’s the drop in replacement?
What do you mean. As in an alternative engine system?
He said they are throw away gear boxes. What is the drop in replacement
@@andrewdoble7973 I see. Nothing is exact but the PRM 120 / 125 use the same mount registration pattern. You have to realign the engine. Technodrive again use the same mount registration pattern. Again a slight remount and alignment. The PRM Hydraulic box the 150 fits but again you'll have to realign the engine and add an oil cooler for this. This is an example and for guidance only.
Good morning.I have bought a Norwegian Moda Tur 24 boat with a BMC 1800 engine.I will not sail until next year.How much can such an engine burn diesel per hour.The boat is 2000 kg.
That is a difficult question to ask. My advice is join BMC engines page on Facebook as there are so many variables to this.

Witan.Mam pytanie.Ile zużywa disla taki silnik na godzinę pracy ?
That can vary immensely, what type of craft is it in, what sort of waters do you work, weight of craft, hull type, gearbox ratio and propeller dimensions, shaft length.

Hi would this model fit to cummins 260hp 2200rpm marine diesels?
You can make anything fit anything. But with that much HP it provably try to spit it off the back. Always best check the manual for the Max rated input power for any gearbox.
hi wonderfull video.....i had an accident on my canal boat yesterday and the nuts fell out of the gear box causing propshaft to misaligh n and gears to grind to a crunch do you think i need to replace any parts or just bolt back together inplace??
Please explain further. What bolts fell out, were from? The alignment will most likely need to be checked
How can I remove the output shaft bearing without splitting the gear box..
You cant. The output flange is part of the shaft and held in place by the rear bearing. You have to split it. Check the exploded diagram in the manual.
great video thanks. I have the same gearbox on my boat and I'm wanting to install the MT5036 oil pressure gauge to be able to monitor the pressure as part of my routine checks - could you tell me where it should be connected to the gearbox as its not specified in the manual - thanks
The forward gear in our marine box was slipping off , we removed and opened it we where very confused on how it worked ( we expected something like sync rings like in a car manual gearbox ) and everything looked fine until I found your video ( the bronze clutch looks exaclty as your worned one ) . Thanks for your video It helped us a lot
Glad it helped. Very repairable boxes good luck
Saludos desde Trujillo Venezuela.. la bomba de inyección que tienes en la meza es de gobernador hidráulico?? Quiero saber ,cuál es el número de los empaque de repuesto 🤔
Hello for old blighty, not sure I understand you. There isnt an injection pump here. Only injectors and my bench top test rig. Have I missed something?
Excellent tuition.
Well done 👍
What do you call that black vertical press thing? Is it required in order to remove and reinstall the shaft?
That is a hydraulic puller, the bearing is pressed into the brass cast body. To remove it you need to press it in order to not damage the bearing. Taking a press into the field is unrealistic so I have the hydraulic puller and I make that into a mini press.
@@dhcrouchmarineltd3049 Great. Thank you!
Would you say the thread on the inside of the forged steel housing is durable enough to use a a fine thread nipple as part of a dent puller/slide hammer removal tool? I have two injectors that simply will not come out no matter how I pry on them.
Hmmmmm, good question. Id say unlikely but what choice do you have. If you take the studs out can you not turn the whole body clockwise, with some lubricant of penetrant oil? These are not modern engines, so not that long an injector. Unless its rusted in. Feel free to send me some images of them. Ill see if i can think of a solution. darrencrouch@dhcrouchmarineltd.co.uk Watsapp 07809607630
@@dhcrouchmarineltd3049 Email sent. Thank you.
Great video, I can now 'see' what's happening inside my Technodrive gearbox. I had an enging rev 'surge' when manouvering at very low speed - it felt as if the input jumped off the forward ourput. Assuming the clutch surfaces aren't worn out am I right in thinking that the clutch can be adjusted by putting an allen key on the selecter barrel/shaft to move the fork?
No, the selection fork needs the float shimmed. It wont help the clutch bite more. The centrifugal forces of the shaft spin will keep the clutch in drive engaged.
@@dhcrouchmarineltd3049 Sorry to be pressing you on this but an online manual has this: Clutch control unit adjustment: with the operating lever ref. 18 in neutral position, turn by hand the output flange ref. 26 and, at the same time, screw the adjusting screw ref. 28 with an alien wrench (4 mm) until the output flange rotation gets hard on a small arc only. Unscrew of 3/4 of turn the adjusting screw and fix it by locking the nut ref. 57.
Yes thats the float depth of the fork. To much in and it binds on the clutch gear. Shimming just keeps it from fowling and jamming on the clutch. So in a sense it is clutch adjustment but not in how the clutch "bites" rather the selection of the clutch cone. Hope that makes sense
@@dhcrouchmarineltd3049 👍
Thanks for the video. How did you determine the correct distance to press the parts on the shaft?
The shaft has a ledge that dictates positioning. Once the bearings are against this ledge / shoulder the rest makes sense.

Hei, i need to learn something.. saildrives have 2.7 or 2.3 times reduction.. or whatever nm is. Where is reduction.. in knee of saildrive where propeller is or inside gear box.
The only way to answer that is to ask what sail drive do you have. Propeller size will also make a difference.

Do you happen to know if I can directly replace a hbw 100 for a zf12? Asap says its the closest thing. My question really is about the dimensions and gearing. Is the gear ratio the same? Will the ratio matter? Also will the adaptor plate fit to my bmc 1500? Will I have to lift or lower the bmc to line it up with the shaft? Any advice is much appreciated as I'm a bit lost..
If I recall correctly it is a pain and yes you have to re-align everything and pull engine back of shaft forward.
Great video, nice style and clarity 😃
i'm just rebuilding one now, i managed to press everything onto the shaft ok. i'm just wondering if there is a sequence and torque spec for rebuilding the case?
Have you got the workshop manual, always refer to the manual for the tolerances and torque sequences.
