Here goes, I have a1996 115 HP Evinrude Intruder with Optic 2000 electrical system. Motor runs great sometimes others it cuts out at full throttle.
Have replaced all gas lines and fittings. Also have ran boat on a small tank.
Carbs have been pro rebuilt.
Powerhead has been pro rebuilt.
External fuel pump.
New stator.
New power pack.
New starter.
Too many more items to lists.
Have not replaced the optic eye.
Any ideas?
I would check fuel pressure.
We put a new electric pump on it, same results.
Plugs?
Several times.
Does it "cut out" slowly or like a switch? If slowly it's likely fuel, if "like a switch" then electrical.
Sounds like the charging coils on the stator may be starting to go. Usually the engine has to be hot before it starts. If it does it when not fully warmed up and running a bit probably not the stator.
New stator is new, same results.
Well I didn't see a rep,y to my last question, but I'll ask a couple more trying to help you
1)Were you having the same problem before the rebuild?
2)Were all those (electrical) parts replaced during the "rebuild"? or did your "mechanic" just start replacing parts to try and find the problem?
If no luck here with the problem try the forum at iBoats.com
All parts replaced at rebuild. Did not have the problem before rebuild. Motor will run great then just start cutting in and out. Ran on small fuel tank, results the same.
Who did the rebuild?Quote:

Genes Marine.
Well it seems as though the re-builder caused the issue, and should be the one trouble shooting it. Sounds one of the parts he replaced is not up to snuff.
He passed away, under new owner.
Well what you need is for someone with test equipment to check all of those electrical parts to see if they are up to spec. Any of those "new" parts could be at fault.
I had a similar issue on my truck once. I replaced a ton of parts, only to find out the new spark plug wires were defective. $80 dealer diagnostic test would have saved me hundreds of dollars in new parts.Quote:

If your unit has the VRO, rebuild your vapor pump. I had the same problem with my 2001 115 and after converting the vro to a regular pump, swapping lines, cleaning carbs, and several other items, It ended up being a $30 and 30 minute fix. The pumps job is to pull out the vapor from the VST, if vapor builds then it fills the chamber and doesn't allow fuel in. Thus it will run fine at idle or mid throttle but any more it cuts out from no fuel. Wouldn't hurt to replace the gasket, float, and needle in the VST either. I did mine when rebuilding the pump. Don't know if it helped or not but my problem is gone.

Thanks for advice, will look into it.
If your outboard is going to WOT then losing power shortly after then that's most likely your issue. If your able to pull back on the throttle to half or less and power returns then it means more fuel is leaving your vst tank than can be replenished when more demand is called for. When applying less throttle not as much fuel is needed. Meaning the fuel can't enter because air(vapor) is filling it. The diaphram in the vapor pump gets hard over time and no longer works to do its job. You will notice that the vapor pump rebuild kit is also a fuel pump rebuild kit depending on the configuration.

Great info, Thanks.
