1884 Chris Craft Scorpion 186 won't start?

[DaleWilcox]

I have a 1984 Chris Craft Scorpion 186. It was running great, last weekend, but when I turned it off and tried to start it back up, cranked and started but then died. I tried to start again but it would not start. I check the carb to see if gas was being pumped when I pushed the accelerator but didnt' see any gas. Is there a way to check and see if the fuel pump has gone out? I just replaced the coil about 4 weeks ago. If it is the fuel pump does anyone have a diagram on the pump so I'd have something to go on if I want to replace it myself? Oh and the engine is a Mercruiser 350, 260hp.
Thanks, Dale

check your fuel filters. remove the fuel line from the carb and slip a short hose over it. have someone crank engine while pumping gas into a clean jug. if not pumping gas into jug then check fuel system from tank to pump. could be crack in a hose sucking air into system, clogged fuel inlet or anti-siphon valve. check maintanence items first filters then go from there

Sir...that exact thing happened to me. Are you running a fuel/water seperator ? The guy at the boating store told me that if the filter gets full of water...it wont let any more fuel thru it. Take it off and dump it out, or replace (preferably) with a new one. Its worth a try.

I have the same boat & messed around with a similar problem for quite a while. it would choke out over 3000 rpm's. I eventually had to install an electric fuel pump. I also installed a clear fuel filter Pro Guage GF61P- they aren't easy to find, but allow you to keep an eye on what is going on- dirt in the line, not enough fuel flow, etc. Hope this helps.
