Thanks
You have a 555 ECM and the HSV ignition
With it doing on acceleration and is intermittent and does not effect performance it might be the in-gear switch on the shift plate. The Bravo drive has just the one switch
It's there to tell the driver the boat is not in gear and rpms are to...
Welcome
Most all are in the engine room bilge. You should 4 thru hull fittings
2 engine thru hulls with strainers
1 generator
1 AC
Follow the one that doesn't go to the engine or Gen
Yes there are various adapters used for the different motors.
But not able to see for Yam or Suz

Have used Techmate for years, and Rinda is the only tool maker other then Mercury G3 and it's dealer only
There are some tools which can display engine data but not so far as clearing codes.
ok, when you said it won't turn over (motor cranking) you mean it won't start, it will crank
Look under the helm I'm thinking either a wire was either missed and not put back on the key switch, or one may have been put on wrong place
There will be a 15 to 20 amp fuse behind the helm and many...
Timing can cause the issue, but most cases it's the carb. When motor gets above 1000 it starts transitioning from the idle circuit to main jets.
Your motor uses a heat exchanger (HE)
In your first thread Bondo mentioned to replace the impeller and housing. If that was done, then need to find...
When key is turned to ON nothing happens, gauges don't energize, etc , correct?
If this is the case look for the 90 amp fuse on the starter post, it's square looking thing. See if you have Battery voltage where the Red/Purple wire connects...
Start by checking compression to verify health of the motor, should be close to 10 Bar. Highest and lowest cylinder pressure should be within 10%
Next get into the carburetor, most likely the idle circuits are clogged
The Merc area is the Mercruiser area. You had it in a section which would get very little views and being a shift issue it is a motor issue
It should help with that, but going all the way to 6 o'clock position may be other issues. Try adjust first then we can see if there are still problems
Move to Merc area
The shift cable needs adjusting
Place shift in neutral, then disconnect lower shift cable. Make sure **** interrupter switch is in center. Move cable in/out until until neutral is found on drive. Adjust barrel nut until cable just slides back on shift plate
Search for 861156A1 which is the old pump number, several will show up
You may have a good pump it's just the Reg is where the problem is, need to test. The pump may be able to output 60 psi of more, but if the Reg bleeds off all pressure except 30 that's all you will see.
The FP Reg is the lower one on the pump. The upper one is a damper and doesn't do much but educe FP pulses
FP Reg cost under $200 which is a lot, and can be had with a automotive part for less

Having cool fuel 2 then should have an Alpha drive
You should also have 43 psi fuel pressure
Has the fuel pressure regulator been changed or tested?
Can also have a vapor lock issue going on but with VL you should have no issue restarting after 30 minutes. The restart issue might happen...
