Re: Low rpms aq125q
Sorry if I didn't give enough info ,I'll start over.
Boat is new to me. Had mech friend look at it said everthing looked okay.
We took it out the first time,and it would not run well.he was trying to adjust carb and stuff when the timing belt broke.
He replaced the belt,checked the time,set the dwell.adjusted the carb. Seemed okay.
I took the boat out again.it started easy,and ran okay. It would only go about 21 mph. There was still plenty of throttle left . But moving the throttle did not increase speed or mph.
I replaced the tac,added some fuel cleaner and octane boost ,as my friend suggested.
The tac seems to work correctly,the fuel is very clean.
Took the boat out yesterday , started great,ran fine up to 3000 rpm. Here again the throttle response stops,no speed gain or rpm. But this time the speed was only about 10 mph. There is still about half the throttle travel left. But moving the throttle dose nothing dose not start sounding bad or anything but no response. It actually seems to be running fine just won't do anything over 3000rpms that's the top. And only ten mph.
So,today with the boat out of the water.it starts fine runs fine. Climbs all the way up the rpm scale to 5000. That is with the boat in neutral .
So under load it will only do 3000rpm in neutral it will easily do 5000rpm? Sounds good all the time no popping or missing ,surging.
Some of the things I've read here suggest that it is not getting enough fuel under load .some suggest a timing issue.
Thanks for all your help,if you need more info just ask . I will keep checking back.
I do agree that throwing parts at it is not the answer,it will get expensive.
Thanks for the help.
