I just traded my 150 merc (carb) for a 1994 efi 200hp. Got less than 30 mins on it and lost power. Idles good but put any kinda power to it and it dies out!! Also had a voltage regulator burn up at the same time. Dealer replaced and test ran at shop not on the lake. Motor still did not power up from idle when I put it back in the lake to run it. Any ideas on what may have happened to the motor and I can start looking to case the problem down?
