    Starting Issues 2300V Limited with Black Scorpion 350 MPI

    So pulling out what little hair I have left. Started having issues with starting our boat. First run out after putting the FAE on, the boat took forever to start in the water. Out of the water, not a problem, barely cranks over and starts right up. In the water, you have to crank, FOREVER and it might sputter a couple of times before it will actually start. I find I have to give it a bit of gas to get it to start. I replaced the cap, rotor, spark plugs and wires and took it out again today, same thing. Ended up keeping it running all day so I didn't have to deal with it. Kind of embarrassing when you have a boat full of people. Beginning of the season (may) I replaced the fuel/water separator filter.

    At this point I am completely lost. Could the FAE actually be causing this? I had one person tell me that they had a similar issue with a same model year Tige. FAE off, they had no problems, FAE on, it took extra cranking to start it up. I don't mind some extra cranking but to the point that I'm afraid of it killing the battery, that is too much.

    To me it seems to be starving for fuel. When you turn the key on, you can hear the fuel pump come on and after you finally get it started, she runs like a champ, no heating issues, nothing.


    Completely lost......

    Regards to fuel pressure, what type of gauge do I need to check at the schrader valve on the rail? From what I can find, there is only one fuel pump. There is nothing in line prior to the fuel separator. I have the cool fuel on the right side.

      This fuel pressure gauge should work.

      Or you could probably buy a small Auto meter gauge and get this adapter and leave it on there permanently.

      This is theoretical. I don't have the same setup as you do. I have a gauge permanently mounted on my TBI setup.

        So took the FAE off today and started like a champ in the water. Had a mechanic buddy out with us today and he also mentioned back pressure caused by the FAE on the motor. If this is the case, how can this be corrected? We love having the FAE on but not being able to reliably start your boat is an issue. Can some adjustment be made to the timing to possibly help this?

        Lost and confused in Newman Lake.....

          Have you tried talking to Larry Man at FAE?

            Planning on getting in touch with them this week.

              That is strange. I was coming on the forum to post the exact thing happening with my boat. I recently purchased a 22v with FAE on it. It is exhibiting the exact same symptoms as your boat. I would be very interested to hear what you figure out.

                Sounds like it's struggling to empty the exhaust system of water and hence not being able to get rid of all the burnt gas. Never seen a FAE but since the outlet is lower it's going to be harder to exhaust. A bit like blowing down a straw in a drink.

                  Found an older post from Larry on another site: The shape of the FAE outlet creates a venturi effect when the boat is moving forward; thus the exhaust is "pulled" from the exhaust system and there is no backpressure issue (similar to the exhaust on an inboard/outboard).

                  So, maybe setup issue? Not properly aligned with the prop? Sent an email to him tonight, will see what his thoughts are.

                    Is it only more difficult when loaded for surfing? There is a lot more water in the exhaust when weighted for surfing. Boatwakes was hypothesizing that surfing might be causing the increase in muffler failures and told me to keep an eye on mine for leaks.

                      Loaded for surfing or not, same issue with starting. It will start okay when first go into the water. We will run out to our spot we like to sit and shut down. After some time (5,10 or 30 mins) go to start up and the above issue happens.

                        We installed one on h20sk8ter's boat this last weekend (2001 2100v 350 mag) and the only thing I noticed was the motor seemed to turn over slow when I was driving the boat but forgot to ask mike about it when we got back (chime in here Mike! Notice anything different about starting?). Hopps, when you removed the FAE to test, did you take off the adapters at the transom exhaust outlet? Those house the traditional out drive exhaust shutters that keep sudden water back-flow from pushing back up into the exhaust system. Check for correct directional operation of those as well as look for blockages in the FAE tubing.
                        Also, after talking with quite a few owners about this, it's going to be imperative to monitor your mufflers and the amount of water the boat takes on after installation. True, this system scavenges exhaust at speed very well. However, starting the engine after sitting creates a hydraulic hammer effect in the exhaust system that I strongly believe has lead to quite a few muffler failures. In no way am I blaming FAE for a design or defect on the marine mufflers installed in the boat already but just trying to keep the word out about what to watch out for.
                        Fixing everyone elses boat just so I can use mine...

                          When I took it off, I did leave the adapters on. So, the flappers/shutters were not on. I wanted to see if I was still having problems, if so, I was going to put it back on at the dock so wanted to keep the adapters on. It seems to me to turn over fine, just cranks and cranks.

                          When it comes to motors I'm not that knowledgeable about how this all works. To me it acts like it is starving for fuel with the FAE on. If is back pressure, what can be done to correct it?

                          As for muffler failures, I already had to fix the right side once. And it looks like it had been fixed once before. Will keep an eye on them if we can get the issue figured out with the FAE on.

                            Spoke to Larry tonight. Recommended replacing the starter. He said he had ran into this issue recently on two other boats and with replacing the starter, fixed the problem. I doubt the starter has ever been replaced (15 years old). Will get one on order and see what happens.

                              Seems a bit odd to need a new starter. Is your battery good? More likely to have an effect.
