I just put my boat in the water this weekend and it has a mercruiser 170 that was rebuilt last year. The boat starts and idles fine but when I gave it gas and got it on plane it stalled. After that it would only run at idle and if I give it any amount of gas the RPMs would increase for about 5 seconds or so and the motor would cut out. Strarting it back up was hard every time it cut out. The distibutor was replaced, new cap and rotor, and timing was set. I'm thinking I may have a bad fuel pump???
