Hi all, greetings from Lake Maggiore - Italy.
I recently bought a old wellcraft 170 (probably one of he the oldest in the world... (2-2-1972)), still good.
It has a mercury EFI 40/60 HP from 2011. The boat was at sea. At home remained stopped 5 months. Now in a Lake.
I have problems when pushing the engine from 3500 to upper values. It goes down after a while then, suddenly, tends to stop. If I push donw the accelerator, the motor works at the minimum. If I repeat these procedures, the threshold where the motor has problems decrease to 3500 to 3000 to 2800. And one day I was not able to start it again. Then I have cleaned the high pressure pump and the gasoline tank. The mechanic pump make some noise, like tic-tac sound (i don't know if is normal). I did not checked candels and filters. Do i need to look at them also ? Or What else to do ?
My impression is that the provision of gasoline has some trouble at higher values. It seems that there is a lack of gasoline , but still i do not know precisely (since it is the first motor I have).
Any suggestion (a part going to a mechanic...)
Thanks!
Pietro
