I have a 1988 johnson 48 hp SPL with remote, been running good for a couple years (since I bought it). Went on vac recently and it ran good the first day, then it refused to run at high throttle, missing a lot. I thought it might be the fuel bulb, replaced it, no luck. Took off the fuel pump, that looks ok and Pappy said once ( I think) that a fuel pump either works or don't, no in between. I used the motor 4 days running around at maybe 1/3 throttle. I noticed a water leak at the bottom of the head jacket, need to fix that, could it cause the motor to throttle down, even when first starting in morning. I think it has the SLOW option. Tell tale is "peeing" strong. Tried new plugs too. Now I'm home, looked at coils, 0 ohms from grd to pri and 254 ohms from grd to sec on both. Spark at plugs look good (strong and blue). I did not hear any alarms. Should I tear into the carbs or what say you? TINBOAT experts.
