Hi all,

Have just been given some bad news on my 950ss Mercury... the block has rusted through number 6 cylinder and it needs a full powerhead restoration. Anyone recommend where I can get this done, or at least a place to start?....

Thanks in advance,
Pete

Makes sense - also explains why no revs when carby intake flaps were closed last weekend! Hopefully the new coat hanger wire connection allows a better boating experience tomorrow. Now, where do I find an original version of what was connecting the flaps at each end of the carburettors, coz I'm not sure coat hanger wire is going to last so well.....?

The choke flaps aren't absolutely necessary. It will probably run a whole lot better if they were removed entirely. However, cold starts will be a little tricky on a V4 'rude . Products like CRC's Aerostart will easily sort that issue out.

In the mid 70's I bought a new 351 Ford V8 Panel Van.. That motor was far happier with the choke flaps removed. Cold starts were very acceptable even with out the use of the anaesthetic gas - Either.

Anyway, I'm sure we'll dig up a replacement choke linkage rod for you.

MERCMAN.

Dumped the boat outside Mark's joint thus arvo for a few weeks of "rehabilitation" . Korumburra must be a decent place, as no one nicked my  boat in the few hours it was outside his place, but I suppose this may also reflect negatively on my boat....

Got out on PPB today - beautiful boating day. Motor ran slightly better than last weekend, but still no “full throttle” - probably managed displacement hull speed at best, and then motor eventually conked out, and we had to ask for a tow in, which was v undignified.

Now going to chuck it to Mark S to resolve, as I just don’t have the skills. Irritatingly, from previous use, I know the motor can run really well, and, whilst I am toying with replacing it with a new one, I really would prefer to keep the old donk on the boat, as the era matches.

I’ll see what Mark can do...just need to deal with a 1.5 hr drive to him, and another 1.5hr drive home from there...

As a non mechanic I think increased air is mixed with increased fuel in the carby resulting in a bigger bang making the piston go quicker and incrementally up go the revs .

Ahhh. Missed that, Neil. Oops.

I can probably fiddle with the skids etc when painting it, and spend some time lying on my back in the ground, splattering paint on my face.

Will hopefully get out with this weekend, now that I've established that outboards need air to work, and then decide I don't want a new motor.

BTW, in terms of basic engine functions,  when the throttle is moved forward, and the air intake to the engine is consequentially increased, what is it that increases the rpm?

 Invert , I was jokin!

Can you move the boat on the trailer and do sections at a time where accessible ?

As to a modern motor - well yes and no ,well No!

Yes, Neil, I realise this. Too hard to do

Boat painting  needs to be "resolved" on the trailer, so might end up painting on some dilute epoxy whilst on trailer, then "bogging" it up, sanding it back as best as I can do and painting, or just " dealing with" the deficiencies until non boating weather, and thinking about it then.

Have thought about painting her on the trailer, but something of a PITA, as the mudguards on the wheels prevent the boat tipping more that 1" to each side, thereby limiting access to the bottom of the hull.

I'm keen to get out on the water, even if paint ain't where I want it to be.

PS mentally toying  with the idea of replacing the 'rude with a modern engine, but would I be evicted from the forum?
