Hoping someone may be able to help - the engine was removed from the boat last fall to replaces raw water pump, starter, altenator etc and repaint - this boat came from Florida and looks like it was sunk. The owner purchased it, hauled it up here (above Maine) and has had issues with it since day one. It is in a SeaRay 220 SunDeck, and has the dual prop Bravo drive.
Engine has been dropped in, but it won't stay running on it's own. If power is applied to the external fuel (booster?) pump it'll run. without it it'll run for 20 - 30 secs cold start, then stall. Will kick but not restart.
There is one conection that the owner is unsure of, a flat connector at the lifting eye of the engine harness - has two pink with blue tracers and two gray (white?) with blue tracers. this is not hooked up, but does look like it has been as it is clean, unlike the rest of the connectors.
Any thoughts?

What settle cool fuel setup is on the motor? If its the style located under the port side motor mount, the boost pump gets its power source there. I've been behind several motor jobs where the shop failed to reconnect the boost pump power to the correct location- the most common mistake is they connect it to the shift switch as it's the same.connector and located closer to the boost pump.. the shift switch serves no purpose on a bravo3 so it doesn't affect shifting, but the boost pump damn sure won't run...

Yes it is under the port side motor mount. I'll check that thanks!
Any idea on the wiring colors?

Owner decided to wire the boost pump in to the fuel pump relay by the motorola box. :(
I don't think this is the best idea as it will be powered all the time the key switch is on.
Got him running this weekend, but I'd sure like to know where the feed wire is supposed to draw from.
