Well that was a bit of a pain in the rear. All the gas was pumped out, filter replaced, fuel line and rail flushed out.
It now runs the way it's supposed to. 😁
Thanks again to all of you for helping out and once again, learned some new things, and of course added another new tool to the...
Couple of questions...
1. There is a cork like gasket between the tank top and fuel sender base plate. Can this be reused? If not, whats this gasket called so I can search to get a replacement?
2. Do I need to use any sealant on the screws to secure the fuel sender to the tank?
3. I've seen...
Yeah, I use 87 octane from the local station....not ethanol free.
I think that settles it, pump it off and discard it. I don't want to risk being left with low octane gas.
Another mechanic i just talked to said to raise the bow of the boat so all the water settles to the back of the tank by the pickup tube and to just pump/syphon the gas out until you see clean gas come out.
In a way I could be lucky in the sense that the pad the trailer is parked on also tilts to...
My tank has ~60 gallons in it.....the DIY issue I see is how do I off load 60 gallons......any tips on what I can do as a DIY or at this point is it better to throw in the towel and just take it to a mechanic and pay 1 kidney, 2 legs and maybe a lung.
Called one mechanic and he charges $10 a...
I think the culprit has been found, picked up some crap gas. Popped the filter out and the fuel at the bottom was cloudy. Dumped the gas out of the filter bowl and dumped it in to a cup and you can see the line.
Tank was topped off before winterizing back in Oct. I keep the tank like 3/4-7/8 full over the winter.
It looks like I didn't mention in the original post, that I did my un-winterizing check ride the week before all this on the topped off tank and I was out for several hours with no issues...
If this helps.....the backfiring only occurred a couple times. When I was accelerating, I heard the "pop" noise from under the so called hood/back seat. I backed off to idle, then tried accelerating again, heard another pop....so maybe 3-4 pops total over the whole course of trying accelerate...
Compression test on a cold engine. Thought this would be the better test without any heat expansion involved. I believe this shows no leaky valves.

The spark plugs look good. Do I shift my focus over to a fuel issue?
Not to go down another path here.....I'm still going to do the compression testing..... Did some additional reading and talking to some other folks and they're pointing me to a fuel issue, specifically a lean fuel condition.
Since everything ran fine 2 day prior and the fact that I topped off...
Any recommendations for an engine compression test kit. I see a couple at harbor freight but I understand I need to find a kit that has the correct size fitting for the spark plug hole.
Monday was kind of a freaky day if you're a superstitious person. After dropping the boat in the water and went to start it, the fuel gauge wasn't working...it was working on Friday. I disconnected/re-connected the connector at the tank and then all was fine. While in the channel heading out...
