Help 2003 SANTE 210 Bogs when in the throttle.Won't plane out.

[AUTaco]

I recently purchased a 2003 Super Air Nautique Team Edition 210 with the Excaliber motor. I got a decent deal on it (so I thought) because it wasn't running very well on the test drive. It would bog down when we hit the throttle but would eventually plane out and run good. I figured it was just some bad gas left untreated over the summer. It only had 1/4 tank of fuel so on the way home we put some fuel treatment in there and filled it up with good fuel. I swapped the fuel filter, threw on some new belts and cleaned the throttle body. I figured this would take care of the issue.

Well now it won't rev up enough to get over 5mph bogging the whole time. It will rev all the way up when I put it in reverse though. Think it could be the fuel pump? Low pressure or High Pressure? I am at a loss at this point on what else it could be and I am losing precious boarding time.

Thoughts?

Does it do it when you rev in neutral or just under load?

It boggs when revving up in Neutral also. I took the low pressure pump apart and cleaned it put it back in and it ran the same but now cuts off and is harder to start. Before it cranked right up. I am going to order a low pressure fuel pump and see if that helps. Spark plugs look fine too!

Sounds like a timing issue honestly. I'd verify that your timing is good to go.

Also here is a thread that mentioned a similar issue and solution. So it could very well be your distributor cap is corroded causing it to mess up the firing order and spark delivery. Easy fix if it's either of the things I mentioned. I'm pretty confident that it's a timing/distributor issue. I have ran into this problem multiple times on boats and cars, so if you need help trouble shooting just hit me up!

It it surging (like its running out of fuel)? if so - check your 60A breaker, it took me about a year to figure out that mine was causing an intermittent open that would shut off the fuel pumps when it was over 2500 rpm (to test the breaker I just bolted both sides to the same terminal). Also, check your perfect pass throttle servo, mine would sometimes "adjust" it self and let way too much slack in the throttle cable so full throttle was about 5mph, no bogging though so probably not the issue.

Other things to check: anti-siphon valve on the fuel tank return line (gets gummed up), get/rent a fuel pressure gauge to see if the fuel pressure drops when its bogging... this will tell you if its a fuel or electrical/timing issue.

Its not Surging. It idles fine, but as soon as I give it gas it bogs and acts like it is running on 4 cylinders with no power to accelerate.

get a gauge and take a look at the fuel pressure (from the Schrader valve on the FCC), I know the fuel line inside the FCC after the HP pump is prone to cracking on some of the earlier years but I think they had fixed the problem by 03. have you checked the air cleaner/spark arrester?

I took the air cleaner off and cleaned it as well as the distributor cap. New Low Pressure pump should be in today. fingers crossed it will solve the issue.

Have you checked and cleaned the anti-siphon valve?? If your boat has one it would likely be located in the fuel supply line right as it comes out the fuel tank tank. On older boats it would be part of the elbow at the top of the tank, brass fitting. Could be worth a look.

I looked and don't believe my boat has one.

I do believe it should have one, right at the top of the tank, maybe take a closer look, pull the fuel line and disassemble whatever brass pieces are there and inspect/clean.
Your symptoms say starving for fuel, in my experience when the LPP goes it just stops pumping or intermittently works, in that case once the HPP drains the FCC, boat stops running. You said you changed the FCC filter and checked all the internal lines of the FCC, have you traced the fuel lines back to the tank to ensure there are no other filters?

If the fuel pump doesn't fix the problem, put a timing light on each plug wire to see if a nice steady flash is apparent for each cylinder. Hard to trouble shoot crossfiring in the cylinders. If any of them look erratic and not steady, it is a sign the spark igniting one or more cylinders at a time. I found this on a brand new out of the box distributor cap from pcm. Happened on vacation, and tried everything. The dealer at the lake couldn't even figure it out. You can get a dist cap and rotor for a '98 vortec chevy truck an any 'zone for less than $20.

the pump didnt change anything. Ive got a new cap ready to go on I will try tomorrow. So Ready to BOARD!

Which one of these is the anti siphoning deal? And this the fuse you are talking about?
