I have a 98 merc 45hp (60 hp powerhead) jet outboard that is having issues. It is on a 16 ft alumacraft flat bottom. Last week i had it out and it Worked perfectly. Good hole shot, smooth top end, no rpm meter but around 28 mph.
The other day I had it out and it was having a hard time getting on plane and it would run 22-24 mph top end. After running for a while it would die. So, I put in a new fuel line; new tank; rebuilt the fuel pump; and now doesn't die after a few minutes of running WOT. It still doesn't reach the correct top speed and has a poor hole shot, sometimes.
Crazy thing now is that it runs perfectly 30% of the time but the other 70% it does not. When two people are in the boat it seems to run better (I adjusted the trim of the jet but didn't help). Also, when I turn sharply, the motor rpm's dive. It doesn't kill the engine but it cuts out until you turn the motor back. I checked for kinks in the fuel line, nothing. I even mess with all the lines going into the motor when it is running straight and it does nothing.
I am wondering if there is a rev limiter on the engine or if I may have an issue with the float in the carbs. Any insight???
