Ok Tony just been out in dark in garden to relook !! neighbours must think im mad !!! Yes correct that bell housing has the fly wheel on the other side of that red wall.. Yes the bell housing section is 1/2 is the fly wheel cavity and 1/2 (the other side of wall) is the drive shaft and distib shaft... Now i got it... Everybody can now breath again !! cracked it Tony 😇... Sorted .. 🤙.. Should run like a dream with some oil back in it !! seeing as only 100ml approx came out... Just hoping no leaks !! but at least i got a spare engine and box !! Really nice quiet engine too...

great we are getting there!! yes the distributor drive will run of the gear box oil as the oil will be both in housing of the fly wheel and gears. My engine had me stumped way back because there was zero oil on my dipstick in my boat bell housing, but obvs because the level was so low that why i was thinking separate engine oil, then dry bell housing and finally a separate gear box with shaft in between . But yes its engine oil, feeds the engine and ANOTHER oil in the bell housing / gearbox.. IF that all makes sense ?? Soooooo what oil in the rear (excuse me!!!) EP140 or engine oil?

That’s all my spare engine photos .. same set up as mine n boat apart from the pipe disconnected from next to engine to bottom bell house I imagine I use the dipstick on bell housing for the oil level on gear box drive .. or to bottom of the spinning gears.. Was curious on that feed on my spare ?

Ok I’ve took a look at my spare identical engine and box .. the engine oil in sump can’t get into bell housing area or gearbox / drive as both separate units .. however as per photo on my spare there is looks like a breather pipe the goes from next to the dipstick to the bottom of bell housing. Possibly a breather I’m guessing and not a feed ??? .. so the box needs engine oil ? Or ep140? ? If so what quantity? Approximately?

Just sucked out only 2 litres from engine 😏 and about 100ml from gearbox !!! Bought my oil and gearbox oil (ep140) .. any idea of quantity of oil needed in the box

Any ideas on an engine oil and gearbox specs for the BMC engine ? What are users putting in ? Regards Nick

Ok been boat set a high level feed into the jabsco and 👍.. was sucking like a £&@!.. picking up an oil sucker tonight to drain oil out .. and will change filter at same time .. replaced to fuel filter x2 which looked like they was old . A lot of water in them .. so will check the fuel filler .. and looks like no one has every drained them on service .. so far so good thanks all for assistance

hi thanks yes i took a photo and ensured the blades where in same direction.. I'll pop back down the boat now and retry !! will update you !!

Also what oil you using for the engine and the gearbox? not synthetic I take it? I closed the sea cock as the water would have just feel onto the trailer below.. Then took brass cap of the sea cock filter and place a funnel in with water and nothing went down / up to the pump.. I did grease the impeller before in case ran dry for a minute so maybe ok will check .. Didnt prime it ? How'd you prime the water ? Thanks

Hi Tony Been the boat today and got here running on the trailer.. Ive put an oil wynnes treatment in to breakdown the oil before i change it so ran it for 2 mins.. on trailer had the sea cock shut but the brass tops off ready to pour in fresh water to cool her down however this never happened the water wasnt sucking up .. last week i replaced the impeller and it drives around ok when running.. Would i guess the impellor wont suck up until the thermo stat opens in the engine once reached temp? Also theres no drain for the oil on bottom of the sump on my engine or even my spare engine.. How do you drain oil? Suck it through the dipstick is all i can think .. thanks Nick

ok i was having a good look today from what i can see.. there is two inlets that go up to the T after the Jabsco. (im guess theres x2 inlets incase one fouls up?).. Then at the T it heads left into the engine block and i imagine circulates till thermo open and kicks it into the exhaust.. And the right T part goes direct into the exhaust as soon as starts up .. ? think im getting there..

Thanks … there’s a complete one on eBay may buy that .. confused still on the water direction on motor ..

Alan where did you get that impeller for the pump from please ?

I bought that space engine bmc and box from ebay.. always good to have a spare at £300!! I will pop down this week to try get my head around the cooling system.. I cracked the small brass tap on port side of engine block and tasted antifreeze, so still trying to work out the systems cooling works.. Will take some covers off and get photos of the pipework.. thanks

Arh thats how it works ! hence newbie.. cheers Tony .. Im still bit confused on the water system but will look at the pipe locations tomrw or next day ...
