1980's ish Mariner 200hp V6 resurrection - any ideas? - Page 4

Try sticking it in a large bucket if you can find something big enough. They don't pump on muffs very well at the best of times.

You don't need to use manufacturer specific brushes. You can source through local suppliers, eBay etc. sometimes you can use ones from other systems and custom them to fit.

On this subject we went into our local alternator store who refused to sell us the brushes yesterday. He said "if I do that you won't buy a new starter off me to replace it with". His logic being by selling the £6 brushes, I don't need a £120 starter. I tried to explain that as I don't need a complete starter anyway he's not getting £120 regardless if he will sell the brushes he had sat on his shelf to me or not! We ended up ordering off eBay.

We took from it that if you know what your doing (ie you know it just needs new brushes) we don't want your custom, if however you have no idea (ie we took the starter in for them to repair) we'd be happy to help - to have been told we needed a new starter and got done for £120!

No wonder these small outlets are going bust with an attitude like that!

Thanks for that mate. Will try from an old dustbin

Made a video of it running tonight.

You can see that as the engine is running and revs, the demand on water from the muffs increases as the amount pissing out the side of the muffs reduces and then increases when the engine is turned off. So it seems to be going in but not coming out anywhere. Although it can't be seen clearly in the video, there is abolutely nothing coming out of the tell tale.

Planning to take the lower leg off at the weekend.

Cheers again for all the help folks, it's much appreciated

It's pumping water-it's coming out of the middle of the prop like it's supposed to. The telltale is just an indicator, not where all the water comes out.

I suspect your telltale is blocked.

Well that's what I thought, but then thought it's possible that the water coming out was just the excess from where it was spilling out of the muffs. But as I write this, I'm thinking that wouldn't be the case as the excess water was running over the top of the prop, not through the middle.

On another note, had a quick look at the gearbox oil last night and it's not good. Doesn't look like it's been changed in a loooong time, so planning to do that as well. But I couldn't find a drain hole in the lower leg, just the vent hole below the cavitation plate? Any thoughts?

Thanks.

Lower leg oil and waterpump changed. Lower leg now back on but for some reason it's really tough to crank now. The new impeller is obviously providing some resistance but nowhere near as much as required to make it this difficult to crank.

I'm yet to go out and buy a new battery (after intial efforts to bring the last one back to life, I think it's a gonner) but the principle remains that it was easy to pull start before and now it's not possible.

Driveshaft and gear shift linkage all went in without any issues so I'm currently struggling to see what's causing the problem. It's easy to pull when the spark plugs are out and then it's as it was before, but the moment they go back in, it's tough.

Any thoughts, much appreciated.
Cheers.

Are you sure you havent put the gear linkage back together wrong and its put itself in gear?

Doe sthe prop spin freely when you turn it by hand?

I'm pretty sure the gear linkage it back together correctly but I will get the leg off and see if that makes a difference.

The prop is currently off but I haven't tried to turn the prop shaft by hand, will do later.

Jonny2488 · 15 May 2012, 19:19

The propshaft turns freely with ease. No luck getting the lower leg off tonight though. Will attempt tomorrow when I've got more time.

Hi guys,

Been a while. Got round to doing some more work on the engine recently. Since my last post I've changed the waterpump kit and replaced some of the old and cracked fuel/breather hoses. It's running much better now but still isn't perfect. It's great to start with but then after about 5minutes and the engine's warm, it struggles to rev properly.

Apologies for the shocking quality but you can just make out then when I go to increase the revs, it's almost stalling as if there is a lack of fuel being supplied to the engine.

Any thoughts would be much appreciated.

Cheers.

Are you just revving it via the carb linkages. that wont work as it doesnt adjust the timing . you need to reev it vai the throttle or the small throttle lever on the box. dont do it from the carb linkages.
Mine doesnt like that at all.

Ahhh. That makes a lot of sense, thanks jezza. Yeah I had been trying both but was mainly using the carb linkages to rev it so that I was able to see what was going on at the same time. It did seem better with the throttle but now I know, I'll only try it that way from now on.

Thanks a lot mate.
