Tohatsu MFS9.8A3 UL 9.8HP 4STR UL (£2,141.41p) in westerly centaur with dead engine

take a look at the links

I reckon that it would be at the back of the cockpit just in front of the tiller

you might need to modify the tiller a bit - although I doubt it

the Centaur cockpit is a massive thing (compared to the slug and Katie L) so still ahead

I agree lads.... a brand new engine in Centaur is the way to go

but what is needed is some lateral thinking to make these old yachts affordable to the likes of myself

I think some loss of cockpit space and the hideous increase in noise level is worth it

D

next time I see a centaur ashore I will get my tape measure out and have a good look

Still reckon you'll lose a good dollop of cockpit space if you want the outboard prop where the inboard prop is. See red box below...

well done that man

you see I think that is perfect

it allows the helmsman to stand in the right place to best steer the boat

the outboard is right at his feet

The fact that the ideal position is a little forward means that, I assume , the rudder stock and tiller can stay as is because it should clear the engine cowl.

Does anyone know how far it is from the bottom of the cockpit to the normal waterline of a Centaur?

so.....

all I want now is a magazine that deals with practical boating problems and solutions to blag an outboard from Tohatsu and dig up a half decent Centaur but with a jiggered a jiggered inboard

Three blokes, a weekend in a shed with a single sheet of half inch ply

a workmate, power saw, self driving screws, a few gallons of poly jollop and two square meters of glass


Job done!

So who knows of a dead Centaur within three hours of Botolph Claydon?

nearly finished the video editing - need a winter project

Dylan,

You have been round and round this argument since I started watching KTL! If I recall theres videos solely devoted to the inboard/outboard/price
risk/reward agonisings. Sometimes you just have to *do*'; not endlessly mull over and worry. Get this motor:

http://www.ebay.co.uk/itm/yanmar-1GM10-Diesel-Engine-/261307900974

Stick it in the Centaur. Job done.

Theres people on this forum who would help out with the fitting Im sure to help keep the price down.

Do it. Please.

what happens to the well/outboard if a dumper of a wave fills the cockpit? will it drain through the well around the OB or swamp it?
 
very condfident

I am pretty confident that the wave will wash out through the large cockpit drain I have created

most outboards can take a bit of wash over them

pretty well designed some of them I have heard

so far while I have been doing KTL neither the slug nor Katie L have had even so much as wet foredecks _ apart from the rain and the snow

hopefully I will be able to continue avoiding the really rough stuff

the weather forecasting has been alarmingly accurate up until now

Please sir !...me sir !....


Try Tam Lin of this parish......

He has a Cenatur with a bu@@erd MD1 and has just bought another boat......I know these things !

Based on the Blackwater....same club as me...

The boats a good 'un....he's spent a lot of time working on it whilst waiting for the engine to be 'fixed'[ I]....(s'funny......that sounds familiar)[/I]

Just for my twopence......Just get a Cenatur......(you know you have always lusted after one)...this one maybe.......slap an outboard on the arse end of it and see how it goes.....

If it's no good ..then ...and only then start cutting holes in the bottom of a perfectly sound and seaworthy boat.

I'm guessing that if the guy who designed the Cenatur thought that the boat would have benefited from an outboard well or it was practical to do so I'm pretty sure he would have made it that way in the first place.

As I say...just my twopence worth


All the best !
 
13 pages and still going strong! yee haa!

I'm defeated - bowing out!

just make sure you wear a good dust mask while you chop the hole. I thought I had a decent mask when I had to grind repairs into the keel matrix in the old boat and ended up coughing my guts up for a fortnight after. Idiot. really cross with myself for that. Dont know what permanent damage I did but I guess I took a good few years off my life. no matter how much money you are trying to save with the outboard, spend a bit on a respirator!

im off to winterise my inboard. course if I had an outboard I could just stick it in the garage....

-.../.-/.-../.-../... -/--- ../-
 
Just another thought......

The veritable Volvo MD1 that lives within my little boat is nearly 50 years old....ok it's had its problems....none of them being insurmountable..... and it's now running great...

So....is anyone out there still regulary using the original outboard that was bought with their boat dating from the 60's...... I very much doubt it!

I'm not talking Seagulls that putter dingies about....but proper, bigger, outboards that would push....say...a Cenatur along at hull speed...

SO ...I reckon that if my 45 year old boat had been fitted with an outboard bracket instead of the inboard...I would conservatively estimate that at least 6 outboards would have been bought...perhaps more?

Would that have been cost effective ??

Keeping an old engine alive can be costly....I've just spent the thin end of £1,000 keeping mine going.....about the same as a nasty little outboard that would only do half the job...

But I'm confident that the £1,000 spent will keep the engine going for at least another 10-15 years.... If I'd bought an outboard I can gaurentee that I would have to buy at least another one..perhaps two...even three within that timescale.

It was just a thought..................

so what is the immobile Centaur worth?

Should I post this for the 3rd time for the hard of seeing? :) My first boat still on it's original Honda BF 7.5 hp from 1981. 7.5 years for a 4 stroke main engine outboard is a gross under estimation. My current engine is 13 years old and works as well as when it was new.

Come on Dylan, as an "ex agricultural engineer" as indeed I am, why on earth can you not strip, rebuild and maintain any inboard diesel of the type being discussed? Nothing more than lawn mower engines on steroids after all.

It is many years since I wielded a spanner for money but there is nothing insurmountable or beyond my (or your) ability to tackle surely.

I would have thought taking a chain saw to a centaur was a totally different skill set.

By the way, whatever happened to the neighbours daughters Seawych project?

Just wondering.

cost and availability of spares for starters...

try finding bits for an MD1

as for the seawych

still in the garden

inside stripped

locker lids replaced

cushions repaired

trailer ready for the road

slow progress

To answer the "how far above the waterline is the cockpit sole of a Centaur" question, a few inches, maybe as much as 10" but more like 4" as far as I can make out.

I would love it to be more so that I could run my cockpit drains out of the transom above the waterline and do away with the current set up with sea cocks that have to be left permanently open.
 
Call me cynical, but who removes a perfectly good diesel engine from a boat just for the fun of it? Any engine that someone's gone to the trouble of wrestling out of a yacht is either:

- being replaced because it's too big or small for the boat it was in (if it's too big, that's a bad thing as it'll never have been able to stretch its legs)
- part of a boat being broken up (and therefore probably pretty old if the boat is that worthless anyway)

or, most likely:

- knackered (cue an ad on ebay "decent condition, just one small problem... should be an easy fix..." - you know the sort of thing)

Of course, the knackered thing applies to outboards too, but it's more common to sell or keep an engine independently of a boat as it doesn't take all day, a bag of tools and a lot of swearing to do so. That, and universal mountings...
 
that is the fear

that is my fear

certainly you can source a replacement inboard for £1,000 or £1500

but you never really know what you are buying

plumb it it in and then find the fault and deal with some new problems

the bloke says he sold it for blah blah

then you have to load it into a van, bring it to the new boat, get the gantry made to put it into position

create the new bearers

when I changed the mountings on the slug lining it up with the drive took a fair amount of time



a new Tohatsu 9.8 is a new engine

brand spankers - not abused, not badly maintained

shove it into the lovely new well and fire it up

I fully understand that the best thing to do is to dig in your pocket for the £5,000 to £8,000 for a new engine installation

but thyat is one heck of a lot of cash

D

PS - I have really enjoyed this thread

thanks for joining in chaps

i apologise for raising the pulses to those who seemed to get angry at the thought of cutting a hole in an English icon

It was amazing to see the way the thread swungs back and forth from "Dylan is a nutter" to "this might work"
