Re: Centaur/Pembroke rudder

Our engine access is like this - I assume it's normal. (It's grubby as there had been so much guano - 2 years' worth- there was a plant growing!)

Centaur rudder removal

Hello, I'm on the club slipway, now on a falling tide, having researched the process of removing the rudder but it won't budge despite judicious hammering with a block I've removed the through-bolt & the collar/indicator turns freely. Is there anything else? I saw mention of a Woodruff key, but can'...

Re: MD2B gearbox seized: overheated?

Problem solved. The actuator 'pivot rod' had seized in its housing. I'm posting this as it could be the cause of other gear change or selection problems. With the gearbox on the bench, I undid the 4 set screws holding the actuator assembly. I think these are 10mm diameter when new-mine were corroded...

Matching missing cabin locker front

Hello, The previous owner of our Centaur replaced a pair of sliding locker fronts with a single piece of plywood into which he put a car stereo & speakers. We'd like to return the locker to use and wondering about getting a passable match with the existing ones. Has anyone been here & done this? Can...

Re: Withdrawing prop shaft

For info, Having undone the coupling bolts and stern gland, I came back to it afresh and separated the coupling from the gearbox with a couple of fairly hefty blows to the side of the coupling with a hammer (and one on the other side as a dead weight) slid it apart with a couple of old chisels and t...

Re: MD2B etc bolt/screw threads?

FWIW, From the YBW forum I have been advised, and it matches what I have found: mostly metric with some imperial bolts.

Re: seized Gearbox md3b from a Pentland

Just a heads up. Mine still isn't back in as I noticed something on the engine floor, below the drive coupling: it was a piece of the rubber spider.
If you take your gearbox out, take the spider out to check it over.
It comes out easily by hand.

Re: seized Gearbox md3b from a Pentland

Mine seized completely, suddenly. What sort of stuck? Mine was working fine then seized. Oil was low but just on the dipstick. Not sure how the actuator is lubricated - presumably by oil fling from the rotating parts. Or not if there is insufficient oil... If you're able to undo the actuator bolts i...

MD2B etc bolt/screw threads?

I may be winning with my gearbox. However, the 4 hex bolts that held the actuator cover on have now had it. The spanner which fitted two of them was 3/8" AF the others were mole-gripped. I had assumed these engines were metric but I've used all sorts so far. I need to get some replacement bolts and ...

Re: Withdrawing prop shaft

JollyRoger, Many thanks for that. In our case, the 'drying' part is relative - I'm not sure if we lose the water completely and there is the mud...so with the rope trick, we (I) wouldn't need to enter the water? Otherwise I might as well just grasp the prop & pull it astern? Given the age of the uni...

Withdrawing prop shaft

My Centaur gearbox situation (monoshift gearbox on MD2B) moved on a bit last night when I managed to undo the bolts holding the gearbox to the engine (a bit fiddly, but only took about half an hour: 8mm hex socket but driven by an 8mm ring spanner on it as there was no room for any ratchet/extension...

Re: Which antifouling for boat moored at Littlehampton?

No advice as such I'm afraid, but following out of similar interest, and also "hello" as we must be neighbours. I asked at the club what people used and there was no definite answer. More 'whatever the best deal' was I think. Certainly not the "we found X works best here" that I was hoping for. Our ...

Re: Penta Horsepower

Can't speak for other models, but may be similar: on my MD2B it was maybe about the same height as the oil filter on the side of the crankcase. And smaller than those shown in the VP guide.

Re: Anyone in the south with an MD2B?

Hi Paul, I'm south, in Littlehampton, so not terribly near Hythe. Also have an MD2B for the foreseeable future, although the future is a bit murky. I'm similarly on a learning curve and getting down & dirty. Also have pretty reasonable general engine/mechanical experience from my earlier petrolhead ...

Re: Oil change suction pump

If Aldi or Lidl aren't obliging, eBay will. I bought a 12v pump for doing this (maybe just over a tenner) but haven't used it for that purpose yet. I did use it to pump 40litres of diesel & that went ok.
