I recently swapped a 98 Evinrude 50hp motor onto my boat. Went through all the usual maintenance for a new-to-me motor - new fuel lines, cleaned the carbs, etc. I've had the boat out 3-4 times with no issues. This last weekend I was running at WOT, and hit a boat wake prety hard and the motor cut out (coincidence??). Now I have no power when the motor is in gear. It revs fine while in neutral, and idles fine in gear. But as soon as I push forward on the throttle it bogs down pretty bad. It isn't running "rough" per say, but I can't get it to go above 3-4 mph.
The only tinkering I did with it this weekend was to pull the carberator covers off the front of the motor to make sure the butterfly valves were synchronized. I noticed while doing this that the gasket around the carb cover (looked kind of like a shallow airbox, like you'd find on a car) was torn. But I was able to reinstall the carb cover with the gasket in place. Not sure if this would have any bearing on my problem.
Does anyone have any suggestions? I plan to check my spark and compression. I see a lot of online responses to similar questions saying to clean the carbs out. But in my mind, all of these issues shouldn't matter since it is running fine in neutral. I would think that this issues affect how the motor runs in general, and not make a difference as far as whether or not it was in gear. Any help would be much appreciated.
