120HP Force No power on low end.

[billum]

I rebuilt the fuel pump, but still have little power. Takes about a minute to get out of hole and runs pretty good on top end.<br />Does not even have enough power to load on trailer. Has new plugs and coils. Anybody have any ideas. Thanks in advance.

Howdy, Billum. Wow! A minute to get on plane is for-cotton-picking-ever!! Gotta tach? What rpm are you getting at WOT? How long have you had this engine? Did it ever work right for you?<br /><br />12Footer is thinking spun hub (I think), I am thinking over-propped. Unless there is some critical fact that we don't know yet, it is likely to be one or the other, but you need a tach or an educated ear to diagnose it. <br /><br />If you have no tach, we need to know type, length and weight of your boat; what pitch prop, if you have a spare prop and its pitch, if you have a speedometer we need speed at WOT.<br /><br />Standing by.<br /><br />JB
