Beauty of a boat, nightmare troubleshooting! CR 250 GI-E
Was in dry storage at dealer for over a year.
Brought to new location, ran the rabbit ears to run, no problems.
Two months later, put in water, started, with fuel pump sound of death.
Removed Fuel pumps, tore apart, cleaned, found broken screw on bottom of unit, drilled out, removed with leather man tool. Put in new screw, after delugeing pumps in separate tank, with Seafoam, seoetate 12 volt power supply, ran for 39+ minutes, pumps pulling and pushing plenty of fuel, changed distributor cap and condenser, was corroded on all contacts due to moisture, oil filter in top starboard side was clogged brown milky mixture, flushed, old oil replaced with new. Found power steering pump empty, filled, checked for leaks, R&R all relays and, removed debris, cleaned all contacts, in top mounted EFI fuse box for starter circuit, fuel pump circuit, tested kill switch to the switch it's self, not yet traced entire life safety kill switch operation. Found missing zirk fitting on our drive, plugged with temp screw until I can find correct metric or sae zirk, now that I think about it, the engine ran last at the temp storage with water hose and bunny ears, but now it's in water, wondering if exhaustmanifold is plugged, ran fine out of water, not in water?? Hmmm! Could it be catalytic converters clogged? Much less resistance when out of water than in with respect to being able to freely move air with no head pressure or static hg pressure in exhaust? Could this warrant tearing apart exhaust manifold? I had mentioned in a prior post that both the EG 5 KW would not start arms well, the electrical contact to open fuel solenoid does not have power when starting EG, just cranks, like the engine. Checked for starter coil spark, plenty there on engine. Replaced what looked like rusty spark plugs, only a few had carbon and oil build up. Blew out gas lines with portable 12 v air compressor, to stir up any sediment that might have blocked the intake of fuel, prime fuel lines old fashioned way, by tasting it. Filled up fuel pump and ran fuel throughout empty canister, checked water cooler in and outer sleeve for debris, cleaned. So, with all that said, other than both motors not starting, could it be worth my time to tear apart exhaust manifold or trouble shoot life safety circuit from beginning to end? 209 hours on boat engine, 95 hours on 5 KW Koehler Gen Set. Ran beautifully prior, I'm at Whit's end, had to stop spinning and take a break. Any thoughts?
