Please reply if anyone can help out. I am not very mechanically inclined but I do try my a$$ off.
Boat sat on trailer unused from September 2018 until now. I did and always have used blue Stabil. Tried to start motor- One battery died over the winter so I replaced both with new batteries. Motor still doesnt start. Removed all filters and found them to have some water (note that this "water" is flammable, but is clearly a seperate layer than the floating fuel).
Replaced external water separator. Drained and replaced internal filters. Removed spark plugs and confirmed they are getting voltage, but plugs/ cylinders are not getting any fuel to them. Found #2 fuse (I think to the vst pump) was blown, replaced fuse. Removed outlet hose from low pressure fuel pump and confirmed it is pumping fuel. Drained VST pump/reservoir? and found it to have water in the fuel. Pumped fresh fuel using primer bulb to attempt to refill VST? not sure if that is how that works. Still wont start. Spark plugs still dry.
Suspect VST/ high pressure fuel pump has failed, or there is a blockage or air in the system somewhere. Since this is a $700 part I need to be sure it is actually bad, is there a way to test this? Is it likely that the #2 fuse going out caused something within the VST system to fail?
Also concerned about large volume of water in fuel. Removed main fuel line from tank to motor (After external fuel filter) and used primer bulb to pump half gallon of fuel into a empty bottle- seems to be approximately half water (note that this "water" is flammable, but is clearly a separate layer than the floating fuel). Well mixed when pumped but settles out to two distinct layers within minutes- to me this suggests I have a layer of bad fuel at the bottom of my tank that meets a layer of good fuel and these layers just so happen to meet right where the fuel pickup is. The boat is jacked way up in the front so all suspected bad gas/water should be at the rear of the tank near the pickup. I plan to try to remove the sunken layer of bad fuel- As worried as I am maybe it is only a gallon or so of bad stuff, but theres over 100 gallons of fuel in there so I really dont want to pump the whole tank.
Background-
Owned 2 years. boat appeared to be neglected by previous owner. Boat and motor ran great first season. Last season boat bogged down, I removed external water separator- appeared very old and full of water. Changed external water separator but fuel issue remained. Removed internal starboard fuel filters and found them full of gas/water mix and suspected float was tripped. Dumped them, cleaned them, replaced fuel filter. Boat ran great and was used at least 50 hours.
