i took my boat out yesterday for the first time in a while its a 15ft ally with a 30 hp 2stroke mariner. i always start it once a week and it always starts. so we launched at palm beach and headed out ,but could only get 10kmph out of it according to the gps, it was going to take an 1hr 25m to go 7kms to the d9. i changed the spark plugs cause i always carry spares being a 2 stroke but no difference. there was a little resistance from the throttle leaver when putting it forward in gear, i was able to push the leaver all the way forward but no power.but it was very hard to get it back to neutral and when i did it just revved its box off sitting there.so i turned it off restarted but it still revving realy high i put it in gear to get back to the ramp and it jumped into gear, i presume it did this because it was revving high made it back alright.now would anyone know what i should look at first at possibly being the cause,either the control box or cables etc etc any info would be greatly apprciated thank you.
