While replacing my clear hoses on my oil injection I now notice that the check vavle going into the VST is leaking. After the motor has been run and then sits, gas seeps back into the clear tubing from the VST. Is this something that I should worry about, can it be cleaned? T
I've read 9 pages on Sea Foam and decarbing but am still not sure how to decarb a 96 Merc 150 EFI safely. I've used Power Tune in a carb motor but have read not to spray cleaner into the boxes of EFI's. Can I spray it into the spark plug holes and let it sit or do I have to mix up a solution...
96 150 efi. Ran it in barrel after changing impeller. With cowl off I'm hearing what I would call valve noise on a car engine. This engine is new to me so I'm wondering if this is normal. Compresson check 120 across, idles fine. Listened with engine stetho-scope on all cylinders and they...
My hydraulic, Sea Star, steering seemed to have too much play. Opened the cap on the helm and noticed it was real low in fluid. Downloaded the bleeding instructions on the Teleflex site and the fluid they say to use. I can't find anything locally that matches. What does everyone use in their...
Can someone tell me what this part is and how to check it. It has two black wires that comes from the bottom of the ECU on a 96 150 EFI. It looks like it should be some type of fuse or fail safe. I'm trying to diagnose a injector problem. I noticed that the insulation had worn through and...
Is there a way to check if the fuel injectors are working on a 96 150 EFI. The fuel pump was un gummed and is now working but it still won't start due to no fuel. Boat sat for 2 years. Fuel pump pressure is 34lbs, but can't get engine to fire. Good spark. Is there a cut off switch or fuse...
I just bought a used ranger with a ranger trail trailer. The mag wheels have a flat matching cover that doesn't appear to allow enough room to install bearing buddies. Clearance appears to be less than an inch. Does anyone have something they use for a better lube system for this set up. It...
I just bought a used Ranger that has the LMS 350. I would appreciate any information from someone that has the same unit. No manual supplied, looking for on. I see that there is a GPS button, how do I check if this is equipt with one? Are these outdated or usable? Thanks T
Was able to free up fuel pump inside VST by filling it with solvent. It did free up but when I pump the ball gas comes out. Is there a float in these like a carb? 96 150 EFI. Book arrives next week. Is there a way to free up the float without taking it apart?
Thanks to the experts on this site I think I might have my gummed up electric fuel pump fixed. 96 150 EFI. I soaked it all night and kept checking it but no hum. Finally it broke loose and runs. Is there suppose to be voltage to this pump even with the key off? I get some. Does the pump...
On my 96 ranger trail I have a Shelby welded on Jack. The small inside gear is stripped on about 6 cogs. Does anyone know if this is replaceable? Replaceing the entire unit would be a job. Thanks, T
Trying to de gum a 96 150 efi. While working on this I unscrewed the cap to the oil reservoir. Now I get 3 beeps when I turn the key on. I don't have my repair manual, on order. Is this due to air in the reservoir?
Just did a compression on a 1996 150 EFI. I removed all the plugs and did a quick check. I did not ground the wires which I now see is the proper way for an outboard. In reviewing past posts some advise, doing this or you could burn up a control box. Please tell me I'm ok. Thanks
Looking at a 1996 Merc 150 EFI that has been sitting 2 years not winterized. The owner said he was told by a mechanic that the fuel system was gummed up, fuel pump etc. What would it take to get this cleaned up and back to working order. I have worked on cars all my life so I'm not afraid to...
