We must have fitted and in many cases used dozens of the big ETECS by now so have a good handle on their ways.

Agreed, like any 2 stroke a good burn after a lot of tick over will help. A common problem can be the belief that putting a bigger engine on but only running it a mid revs will be better. Not always the case.

Carbon guard (sold by Evinrude) can be sprayed into the air manifold and if having done a lot of low rev work can make a huge difference. Cost retail about 7 a can.

As per other post a deflector pin on the injector can be fitted by an approved Evinrude dealer.

Lastly if changing your own plugs always re-gap before fitting (never assume they are correct). From memory 25tho on the Etec plugs. Most important though is that they must be alinged correctly with the injector.

Cheers

Can you expand on what these injector pins are for, and what they do? Also, what do you mean by aligninging the plugs with the injectors?

I may be on the verge of ordering a 90 ETEC for my Searider, and I'd like to know what I'm getting into!

Thanks.

Apart from this, and the occasional stall immediately after high speed running ...

I used to have that problem. When entering the harbour at low speed the engine used to be running unstable at idle, and often stalled. Every time the engine did this, is was easy to restart it. This problem never happened when the engine was cold.

where are these pins in your engine and how do they change the running?

Explains it all - funnily enough we used to have to do the same trick on some of the 2 stroke model racing engines.
