As per my other posts. It’s now all sorted. , was incompatibility of omap injector bodies and Bosch nozzles. , replaced with matching omap nozzles and smoke totally cleared , ,, was a good learning course and now my diesel knowledge is pretty good. , and that pays on a boat ,

Smoke issue all sorted. , it was an incompatibility between the injector body and nozzles , One made by Bosch. One made by Omap. We sourced two new nozzles made by omap and now it’s running clear and good , , although it was never that bad , it’s now like a new happy engine

Engine smoke sorted. Was incompatibility on injector body and injector nozzles. , although they had been tested , seems like they didn’t atomise enough , engine now running clean and sorted ,

Well guys been a while but all sorted , problem with smoke was the injector nozzles and incompatibility to injector body , we sourced two new nozzles to match the body , all along we had had them checked by professionals , on this engine the injector body and nozzle has to match. We had a Omar body and Bosch nozzles , , so now clean running engine , top half rebuilt and should go on for years.

Well after a while we have finally got a clean running engine , retarded the timing which increased the revs. , then adjusted smoke screw which is basically fuel amount till revs drop , and bingo. No smoke , it’s sluggish on the throttle but that’s fine as long as a cleaner engine , running sweet , sounding nice. ,

Hi yes injectors have been out and checked for correct pressure opening and spray pattern and type , , , the only other thing we were concerned about was injector copper washer size, books says .5 mm. But it had 1mm in before top was redone , due to the smoke issue as our mechanic thought it was glazed bores. , but seems that wasn’t the problem , as it still has smoke issues , we have gone back to .5 . mm , As I stated the head was skimmed and pressure tested , , it seems to me the problem is fuel or rather how it’s burned , ,

Hi we have been running it for probably 9 months at weekends so I believe it’s run in , shim was damaged , and was not running right with just one shim , my feeler gauges have been set at same height , still grey smoke , ,

Hi guys. Ruggerini rm 278 direct injection , the further saga of trying to get the boat running better , saga so far , top end rebuild inc new pistons ,liners and rings , , we thought maybe engine was running cold , however after water pump failed this was obviously not the case , . When engine was put back together the mechanic stated no timing marks anywhere , it’s timed by shims under injector pump , we have had injectors tested , pump tested , tank cleaned. , all filters new , at the moment I have the injector pump lifted on feeler gauges. There was one shim under the pump.5 mm height I would guess at , this has been removed and feeler gauges used to advance or retard timing by height , with no gauge in I assume fully advanced, . With no load and revved engine is quite clear of smoke . When running it has greyish smoke , not clouds but more than I would like , i with no marks ,how can I time this correctly ?

Hi guys , we are thinking of an upgrade , we have a 45 ft boat , currently 2 cylinder engine , , 25 years old boat , keel cooled , it runs fine , maybe bit noisy , not as clean as it was ,,it vibrates as a 2 cylinder, we’re near lichfield , any suggestions as to new or recon with 12 ,month warranty. ,? 3 cylinder min ,, best make ? Advised h power . ? And where to get a quote , , ,

It is a 25 year old marinised Italian tractor engine 1250 2 cylinder ,, we had the head stripped new liners and bores as my engine man said this was why it smoked. ,very pale blue /grey , even on tickover , so we are £2000 down and engine still smokes , , it is not real bad. But more than most boats I have seen , quite a strong smell, , chap from key diesel looked and though fuel issue as it runs good. Sounds good , we assumed it wasn’t burning the diesel due to low head temp , but with the water pump just failed and smoke still present this can’t be the case , as I said book says use .5 mm copper seals under injectors. , when we did strip , one side had a 1mm. Other. Two .5 mm. , we replaced with 1.5 mm , , , we still have light grey smoke on all revs and even tickover , I’ve altered timing several times and has no difference ,, someone else suggested a partially blocked car boned up exhaust , , we do have a bit of black soot on exhaust , as we have a90 degree bend pushed into outer exhaust hole to steer smoke away from rear of boat

Hi tony . Sorry not been on here for a while , I’m back to square one at the moment , , yes I mean the copper washers the injector sits on , I have read that this height can drastically alter smoke amounts , , the book says use .5 mm washers. , , but we have 1.5 mm in now , however the head has been skimmed , , we thought was a temp problem but I don’t think so now , as the water pump just packed in and we ran for quite a while with no pump and still smoked. , any help appreciated ,

Hi , cooling is via skin tank. Not raw , the woodruff key was broken , the pulley head was turning and shaft not turning , so alloy onto alloy and has worn part of shaft away , I think the water is just a flow from the expansion. Tank through engine and out through bearings failed seal , , as the stat is in the exhaust jacket it may be opening with exhaust heat rather than water temp , either way the engine is running cold with no cooling fan ,,

Hi all , I’ve posted on here a while ago , got ruggerini rm278 2 cylinder , , we have had smoke issues. Not major but more than I’d like , we thought due to a temperature issue , the boat engine never gets more than 65 degrees hot , on its gauge and verified with digital gun, we clamped a hose to try to increase , last week water pump was throwing water out , today I have removed the pump and found the woodruff key was broken so it was spinning the pulley and not even pumping .stat checked and opens at 80 so my question is. Would not my engine get too hot in this case? im confused how water would be still coming out of pump bearings when not turning , any help appreciated ,

Hi, we didn’t need compression tests as it has had new liners and piston rings , , I pulled the fuel pump off and all the shims , then put feeler gauges under it and ran it with different heights ,at this moment in time the smoke is ok when she’s warm , as the temp only seems to get to about 70 degrees. I’ve clamped a hose down a bit to limit water to get it to run hotter,,, we have been running like this since summer , as the fuel pump has no shims under ,slight oil from its mount but not major , , it’s usable , we still shut it off in locks. , but as a holiday weekend boat it’s ok , , we will probably upgrade the boat in about a year so don’t want to spend ££££ On new engine unless a real good cheap new one comes along, To be fair , it always starts good, and people seem to like the 2 cylinder pop pop , , ,, never a dull moment and always something to alter , Ant

Hi guys. , on my ruggerini rm278 after a rebuild by a professional , my injectors had 2x .5 mm one side. And 1mm the other ! My book says use .5 mm. , , when I replaced the nozzles all the shop had was 1.5 , , so atm I have 2mmNot right I know , it’s running well but light grey smoke , .does anyone know what difference the size makes as to smoke ? . Will.5 give less unburned diesel which I appear to be getting ,,,,,. atm as we have no timing marks. I’m running with feeler gauges under the fuel pump to simulate shims till I get a sweet spot , not ideal but works , Cheers guys.
