Hello all. I have a 1998 Gibson Sport Series with twin Crusader Champions in red. I am the 3rd owner and have had to boat for 8 years. The port engine starts and runs great. The starboard has always been a bit harder to start but once running has been fine. Fast forward to today, I have been unable to start the starboard motor and have not been able to this season.
Below is what I have done and what I have tested.
Where I have focused:
I know I need to test the fuel pump between the carb and the tank and basically trace/test fuel flow all the way to the carb. If fuel is flowing, then the issue must be in the carb itself (blocked jet or metering block?). If that is the case, there does not appear to be a replacement carb that matches the original (see pic below).
Any advice and guidance would be greatly appreciated. The boat is kept in Georgia (Lake Lanier) and for the life of me I cannot get ANY mechanic to come look at it (very aggravating).
Thanks!
Below is what I have done and what I have tested.
- New starting battery
- New fuel/water filter (old one had some black gumminess at the bottom and some water which represented as red/dark)
- I've only every used marine (non-ethanol) gas. Prior owners I cannot vouch for.
- If I add a little bit if fuel directly to carb throat, the engine will start and run
- Engine has no electrical fuel pumps - everything is mechanical
Where I have focused:
- I have confirmed that if I put the throttle all the way forward (before cranking) that no fuel comes from the secondary carb
- If I manually actuate the accelerator pump (on secondary carb) i hear gas trying to move but none comes out
- I have confirmed that the secondary carb has fuel in it (I removed the screw to 'see' and actuated the accelerator pump and see fuel coming (slightly) out of the hole where the screw was
