Suitably sized and powered vintage replacement for our BMC 1.8

[Neil Smith]

Even a TS3, a bit more grunt I think.

I as Gazza said would just improve the cooling. I am assuming that the pipework has been thoroughly checked. Cant remember if he has heat exchanger of if it really is raw water.

My Beta 2203 gets hot when I am pushing it but thats down to a slight restriction in the pipework and being fractionally over propped. Normal cruising 5mph its fine, its when I push it above 7 it starts to complain.

[Athy]

Ohhhh, I like the cut of your jib - a Lister SR/ST should go in the hole.

 

I think chop! Is evolved in music so probably won't mind the din

I was thinking along those lines, but I think an SR3 would struggle to power a pair of boats, would it not?

Not sure what sizes Sabbs come in - I have seen the singles and an occasional twin but a bigger one might be needed.

It shouldn't struggle, the SR3 was rated at 18hp (proper English ones, not these namby pamby watered down things of today!)

 

I guess it depends on the sort of progress chop! Wants to make. The 1.8 should be well capable and keep its head without boiling over if all is right with the setup.

 

Bernard, discussed earlier wanted to go from the easy route of a modern fit and forget jap engine to a dirty great old bit of English iron for reasons I never fully grasped, as Loddon pointed out, the CE went the way if the majority of CE's - chop! Be warned, better the devil you know

Apart from the noise (which I don't mind but the mrs doesn't like) an ST3 is a very easy engine to live with.

Given the OP's desire for a vintage lump, I hardly think these 1970s Listers being suggested are quite what he had in mind. They are no more vintage than his current engine.

 

I think conversion to trad by construction of a nice engine room and gracing it with, say, a Kelvin J3 would press all the right buttons for the OP. Should get change out of £30k, if he picks the right boatyard.

Chop probably hasn't got enough hight under the floorboards for a slightly bigger size air-cooled Lister, type HR-2.

 

Those HR-2 engines running @ 1500n will give 21.5 Hp, and have when needed another 700n available to get to 29.5 Hp @ 2200n.

 

I bought 2 of these hand start engines with low hours and Lister 3 : 1 gearboxes a couple of years ago for a project that will never see the light anymore.

 

If he has the space one of these would easily move his 2 boats (and maybe a couple of waterskiers aswell).

As SWMBO doesn't like the racket, why discuss at all? Your choice was made for you at the outset, your going diesel electric, bite the bullet and get on with it

A J3, like in Dave Moore's boat Resolute, is a beautiful thing.

It's worse than that. Far, far worse. SWMBO has decided she's bored of boating "I live in it, I don't want to go on holiday in it as well" so at the moment most of my time is being spent converting a VW T4 in a camper. It's not all bad, as part of the conversion I've dropped in a 1Z lump out of a Golf tdi, swapped injectors and when it's remapped on a rolling road at the end of the month I'm expecting ~150hp

Indeed, and is as different from a Lister SR/ST (as recommended earlier) as a Bentley is from a Trabant!

I'm interested in the oil cooler for the BMC, which has a Bowman fitted (yes, I rodded it) skimmed the head too, fitted more solid pipe, lengthened raw water pick-up, turned over worn end cap on pump. I find it strange that even when she starts bubbling up, the raw water out of the side is cold, surely it should get a little warm.

I don't think SWSBO would like the racket from an air cooled & we'd lose our free hot water. She says no to an engine room but that I can have an engine porn window in the cockpit deck! LOL!

I have a reasonable pot for the right engine but not bottomless pockets

[gazza]

Chop!

 

are you going to be down Tichmarsh way in the near future? You are welcome to look at ours

http://www.asap-supplies.com/search/rg/oil-cooler-adaptor-kit-bmc1500-and-bmc2500-203701aasap dont stock it anymore but this is the sort of thing you want.

 

You then fit a bowman oil cooler

[Chop!]

Where would I find a sandwich type oil cooler as fitted to your 1.5 then Gazza?

Oops! Posts crossed mid-channel, I'm near Belfort at the Eurockeenes festival, back in Blighty tomorrow, ferries permitting!

[gazza]

I'll PM you my mobile number, you can drop us a text if you are about. Most of the time I'm only 15 mins from the boat.

Can I assume from that and the fact you have a calorifier that you have a heat exchanger and its not raw water cooled but indirect cooled?

If that is the case have you checked all of both systems for blockages? A bit of impeller in the tubestack will easily cause an overheat.

[Chop!]

Hi Julian, as I said before, I've had the exchanger to bits and rodded the tubes, I'm puzzled that the raw water exits cold, surely it should warm a little on it's passage through a hot engine. I've taken to running the pump to the back boiler on our Jotul range, so that it acts as an additional heat exchanger.
