ABQ------Do you know what the time frame is for these injectors to operate.----You could calculate this with an engine running at 5500 RPM.-----Let us know the amount of time available in which an injector must operate.
Ok now is a good time to give you the 2 month history
Long post. for two questions. All of my first two months history with this rig. In December, for a few dollars, won a very clean, Very Good Condition. Garage kept 1999 OMC 17' Ski and Fish Javelin suited with a 1999 Evinrude 115HP FICHT. E115FPLEEN. The rig is in almost new condition. Well kept. I won the boat at auction so I was only able to gather very little from the owner. I've read the bad about the Evinrude FICHT 1st GEN motors but a lot of the majior problems were not with the 115hp and lower HP power heads. The tank was bone dry and clean. One can of sea foam to start, 25 gallons of REG chevron gas (88 octane @ 5000ft elevation).
First attempt at the lake, engine failed to start.
Back at home, I read forms....I Purchased a fuel injection test kit. Spark plugs, Fuel filter. I hook up the pressure gage and 0 psi was the result with key in run position. I checked, It is sending 12Volts to the fuel pump. I pulled the Carter fuel pump with the vapor canister and disassembled it. Yes the thing everyone says is not fixable. I cleaned it up. I managed to get the frozen fuel pump to free up and run. I reassembled the contraption and hook it back up. Now I have 25 psi fuel pressure. Ok...I read more forms.... Change the Fuel filter, Gap new Plugs. Index new plugs. Hose and muffs in place water on, I hook up the computer. It starts!
It ran at high Idol 1600 rpms for 6 min I bump the throttle it now runs at 650-655 RPMs. The PC connection using the Evinrude software acquired from ebay, shows no faults. OK it say Run Hours are 79. and something. The software tells me the break in period has been accomplished. Nothing Else.
Back at the lake, Hard to start but after 15 min got it running. Idled it at 650 rmps the dock for 15 min. head out to open water shift into gear, DEAD! re start shift into gear with a lots of throttle feathering and simultaneously choking. got it to plow water at 2500 RPM at WOT. I go for about 15 min to the far side of the lake. i let the engine run, for an hour while I fish the cold winter waters. After 1 hour I shut it off and continue to fish for a couple more hours. I start up the engine after 2 hours it fires and runs with one crank! All right! I shift into gear, the engine engages and runs. I head back across the lake, this time with a lot less throttle feathering. I make 2800 rpms and was able to get on plane. On plane I make 4200RMP's. Wind is in my face the lake is to rough to continue at this speed. I seek shelter on the west shore and continue to troll with my main motor at 2.2 MPH. I drop off the Wife and boy at the dock. I secure everything loose in the boat and go back out to open water. Without feathering now just a sluggish throttle control, I get to 2800 rpm and minipulate trim to get on plane, there i was able to WOT GPS says making 37.2 MPH, WOT only making 5200 RPMs. Ran out of day time I spin it around and trailer my boat.
I'm thinking the injectors are still dirty. Getting better as the engine runs with clean gas and SeaFoam to Help de-carbonize the power head. I'm going to purchase an old head, so I can mount one injector at a time. I'll flood and fire the injector with 30 psi air behind 100% B-12 injector cleaner. let it set for 15 min come back and fire it 10 more times. Flood the injector body and let rest, repeat until the injector shoots clean. (this type of injector is not like the automotive type, it comes apart when not installed on the power head) I've always worked on my own stuff.
Any one got any new magic i have'nt tried. I'm just still green to this motor and its design.
