I have a 1986 prov 150 2 stroke outboard. I had the carbs rebuilt a couple of years ago.
But whenever i go out on it the motor seems to run great but then once it gets warmed up ill floor it and will only do 1500 rpms and will shake real bad.

Anybody know how to fix this cause i just wanna go fishing and cant aford to take it some where.
 
Re: Please Help!

You had the carbs done a couple years back - did it run fine after that?

When was it last running "fine"?

Has this just come out of storage and you are running on last years gas, plugs that are a few years old etc?

It could be clogged carbs again, a bad fuel pump or even an iginition problem - so a few more details are needed...

It ran great after the carbs were done.

It started doing this last year and the gas was new same with the plugs.
