I have several buddies with boats on lifts minutes from me I usually fish the bay with so my Pro-Line just sits.....and sits. I usually start it on the hose at least every 3 weeks and run ethanol free 91, Stabil blue and Sea Foam in it. Always fires right up but not last week. I figured it was the over 2 year old fuel.
I siphoned out all 8 gallons and it smelled like paint thinner
. The external fuel water separator filter looked great but the little spin on filter at the lift pump under the cowl was full of rusty bits when I poured it out. Shit, I'm thinking $500 for a new downstream recirculation pump and $300 times 4 for new high pressure injectors and the PITA of recalabrating the EMM/injectors with my software.
This morning I refueled with 15 gals of fresh fuel then topped off the new filters and installed. I removed the schrader valve on the high pressure side and pumped at least a half gallon through the recirculation pump with the hand pump bubble until it came out clean without any specks of rusty crap. It took about 3 20 second cycles (with a one hour battery charge in between) for it to fire up. Idled perfectly for 5 minutes with head temps between 102-105 degrees. Ran it a good 5 minutes after the thermostats opened at 1,600 RPM with all 4 head temps reading between 99-101. It just purred.
Idled it for a few minutes more and it sounds perfect.
I'm tickled. Gonna dunk it next Mon. and leave it docked all week behind a friends house and use it everyday. Use it or lose it.
