engine

Thanks again for all the helpful replies, i didnt expect such a welcoming response, I am glad you have mentioned a parts supplier, i have been finding it difficult online to find one, so i will ring him today

I have got quite an in depth knowledge on engine building (I do race cars) buts its been years since i turned my hand to 2 strokes, last time i did it was motorbikes in my youth! These outboards look a bit more complicated, but i guess in practice 2 strokes are all the same.

I'll get the parts ordered then with a new pulse pipe and diapghram kit for the fuel pump, plugs etc and go from there.

I'll report back with my results.

Just spoke to him at blackdog marine and hes confirmed what Uncle Al's said, the engine was doing what he called "sneezing" which it had been doing intermittently and its blown that pipe off.

So need to reset the carbs and then the check timing

Thanks all!

rib

Its a very clean rib, having it retubed in 2009 has definetly made a huge difference. Upon purchase and inspection I was really happy with it and paid a great price for it at only 4450, knocked him down from his original 4800 figure.

However upon getting home I have noticed a few things wrong with it which i didnt pick up on on viewing which was slightly anoying, in particular.

1. The onboard VHF radio for some reason can only receive incomming transmissions, it doesnt work when it transmits. Tested the mic and everything and its just dead completly with no output. So no biggy on that really but it would have been nice to been told!!

2. The bilge pump was knackered so i have ordered a new one

3. The rev counter doesnt work

4. Dropping the gearbox oil, it was milky as hell so its been contaminated with water. I noticed there were no gaskets on the screw holes for emptying/topping up, so potentially leaking there.

5. The engine blew off a pipe the other day and is sneezing badly at the moment so needs the carbs setup.

Aside from the above points lol its a lovely rib, I just need to spend maybe 200 on it to get it back to its former glory so all in all I think I am going to have a great summer!

The VHF may have never been used in anger so he might not have known it was fooked?
Looking at the RIB I'd say you did alright.

As I have the same engine please update when you have it fixed, one more thing to worry about! On mine the stator went with less than 20 hours use. I am sure yours has the new red one but if not carry a spare engine as its apparently not a question of if but when...

A big thank you to www.blackdogmarine.com for getting me the parts in less than 24hrs, i ordered them 1 oclock yesterday and they turned up at 9am this morning, how is that for service!

Parts cost about 8 so hoping this is going to be a cheap repair once i have set the carbs up and checked the timing.

Yep, I recognise this. Always wondered where that burned spot came from;
One of the the previous owners of my 40 Merc also suffered the very same. Pipe from the same type of fuel pump blew out and burned + also made a small crack in the hood, glad you were more vigilant than he was...

I guess it was the retarted timing on mine..
Mercury was testing new TPM modules early 90ties to replace need of a rotating trigger, and somehow improving the ignition. The TPM went to crap, and not just mine I guess, as they dropped the TPM ignition just 2 years later
