Thanks Biffer. There's no way I could have done it properly, very grateful. Learnt so much today!

Standard sealant or adhesive sealant? (Decided to do the whole console)

Standard sealer. If you ever have to take it off again it will be a nightmare if it stuck down as well as bolted.
It's worth thinking about a couple of things. Once it's sealed down any water you get in there through seat etc will not come out also your boat has no way other than the bilge pump to get any water out of it. If the pump fails you'll be in the crap. Imagine trying to recover a swamped boat with no deck or hull drain. If you're going to open up hull as you said then a small transom bung at deck level would be good

Good news and bad news

The good news is I have now finished the hull and repainted. I have also re stuck all of the rubbing strake back on, almost 2 meters had come off! Worked a lot in the week to get it all ready for the weekend. Will be getting some pictures up tomorrow

Wanted to check the engine is ok so decided to run it for 15 mins. Started second attempt and smoked a lot. I presume it's because of the temp? -2 to -4 let it idle for 2 mins before increasing the revs a tiny bit. As soon as i did that it cut out. Started again and this time put it in gear, again cut out. Would not start at all. left it 5 mins and then it started for a few seconds. Didn’t sound healthy at all. Sounded as if it was about to die then jump back into life before eventually cutting out. Any throttle and it would either cut out or just not start. It’s getting fuel fine and compression was at 9-8.9 bar on all cylinders. Oil is on an amber light and at one point it continuously beeped when i turned the ignition on, could this be the problem? The reason I’m sceptical its oil is that it seems to be burning plenty of it and you can definitely smell it.
Spark plugs are corroded on the outside however one is much worse than the others. Could this be the problem?

Thanks

I don't know what engine you have Nathan, but it sounds as if some kind of low oil protection could be activating. Even if there's oil there, a level switch or sensor could be faulty & sending a low oil signal which is preventing the engine from revving.

Nathan k · 09 February 2012, 21:03

I'll be getting spark plugs and oil tomorrow. is it normal for a spark plug to look like that?
the engine is a 2004 yamaha 40hp VETO

Nos4r2 · 09 February 2012, 22:54

I'd bet the corroded one was on the bottom.

Can you make those images a bit smaller?

hi this is a good link

I've seen worse plugs. Can't see the tips properly in the photos. The wet/oily/black appearance could be from trying to start the engine. You need to pull them after the engine has had a good run & got upto temp & have a look at them then. It won't hurt to replace them & get a couple of spares. Make sure that they are gapped correctly before you fit 'em.

SPR · 10 February 2012, 09:35

surely you notice the condition of the plugs when you did the compression test before you bought it.....or have they corroded since .. eek

Nathan k · 10 February 2012, 21:48

Had a look in fuel tank and found water in it. saved as much fuel as I could and chucked the rest. took out drain screws in top and middle carb and flushed them through (I couldn't get to bottom one) going to pop in to BHG tomorrow to get them to undo it.
The engine ran MUCH better, would run for 4-5 mins if left to idle before slowly dying out. If I increased revs for a few seconds then back to idle it would take another 4-5 mins before dying. does this sound like a problem with one carb and would flushing it out solve it?
Also fitted new spark plugs and topped up on oil.

spartacus · 11 February 2012, 08:11

Sounds like the carbs to me. Try new plugs after gapping properly, fresh fuel (including cleaning fuel filer bowl on engine), also worth investing in external fuel filter. Just a thought - but have you checked condition of thermostat?

Nathan k · 11 February 2012, 12:47

Thanks spartacus, what does the thermostat control? I will be investing in a external fuel/water separator. Drained the 3rd carb today. BHG marine were extremely helpful as usual, had it all done in 30 mins including testing engine. went out for a quick trip to the IOW and back and all seemed ok. Anyone up for a solent blast?

Sounds like the learning is ongoing ..with the changes in temp from day to night condensation in tanks can be a bugger.

Outboard cooling. Just wondered if the thermostat was salted up which could cause problems with overheating and rough idling. Used to have a mint 1995 Yammie 6H4 40v and the thermostat needed annual checks. If you're investigating, watch as there is a gasket which will no doubt stick to the block or thermostat housing and tears on removal. Invest in one of these before taking a closer look. Glad you got it fixed.
