I took out my boat today on another test run.. the weather was horrible in miami.. lmao.... Both motors started up fine but when i put them in gear and give it full throttle the boat would only go as fast as if i was in a minimum wake zone... very little power. How can regulate the idle or make the adjustment so when i do push the throttle it actually goes faster ???? the other problem i was having after a while was the motors would cut off when i put them in gear ?? any suggesstions ????


Thanks

ohhh and mon nuetral the motors rev perfect its just on gear that it doesnt have any power... now if i do it in the water manual then it goes fast... need to know how to adjust the the motors in gear to the throttle i guess... dont know much but it has to be regulated.....

not really sure exactly what your problem is..but standard troubleshooting starts with..check fire on all cylinders, check compression, check fuel lines, connections, pump...and new spark plugs and filters. also check all cable, throttle connections and linkages

Realistically, what are the chances that exactly the same thing can be wrong with both engines? Look for something common to both engines. i.e. garbage gas.
