If your gas is old, replace it.....also, run some Seafoam thru your gas to clean the motor interior.....also, check your primer bulb for cracks....as they get old, hairline cracks appear and will suck air into the system causing a stall.....check for a clogged fuel filter if you have one.....check your plugs.....do all that before a carb rebuild...

It's been an ongoing issue since I brought it down to Leeville in November. I brought it to a mechanic and he found a bad power pack. He also took a sample of the fuel and said it was good. Took it out a couple weeks ago for the first time since the repair and it did the same thing, didn't get over 2000 rpm. I changed out the bulb, installed a fuel filter, and replaced the fuel line from the tank to the bulb before taking it out today. It ran better but seems like I could have a plugged jet. I just took the cover off to see if there was another fuel filter anywhere. When I took the ?air box? off I noticed a line disconnected and the intakes of the carburetors were wet. I'm no mechanic but seems like this should be dry. I can't figure out where the hose connects to.

I'm going to try to run some sea foam thru the carbs. The hose that I found disconnected might have been from the vro pump that was taken off by the original owner. I think sea foam might do the trick. I've replaced the spark plugs, bulb, fuel filter, and fuel line. The only thing left is the gas which isn't very old and is non-ethanol. If this doesn't work I'm going to rebuild the carbs. Thanks for the advice.

Found this below on the web.....don't know if it applies or not.....at any rate, I would make sure that hose was plugged since not in use.....


"You can convert the VRO pump into a straight fuel pump, eliminating the oil tank and VRO pump warning system, but retain the overheat warning setup (and fuel restriction warning if so equipped) by doing the following:

1 - Cut and plug the oil line at the engine so that the oil side of the VRO pump will not draw air into its system. Trace the wires from the back of the VRO to its rubber plug (electrical plug) and disconnect it.

2 - Trace the two wires from the oil tank to the engine, disconnect those two wires, then remove them and the oil tank.

3 - Mix the 50/1 oil in the proper amount with whatever quantity fuel you have. Disconnect the fuel line at the engine. Pump the fuel primer bulb until fuel exits that hose with the tint of whatever oil you used. Reconnect the fuel hose.

That's it. If you want to test the heat warning system to ease your mind, have the key in the on position, then ground out the tan heat sensor wire that you'll find protruding from the cylinder head. The warning horn should sound off."

Thanks for that info. I'm going to call the mechanic that worked on it today. Since the problem wasn't fixed, he should at least troubleshoot it without charge. I was referred to him by numerous people so I trust his work. He found the bad power pack but I don't think that was the main problem. I've never really worked on outboards so I don't want to get too far into this one without knowing what I'm doing. I'll ask him about the vro pump and what's mentioned above.

It apeaes to be a crank case vent or bleeder. Look where the other one goes to and compare the other cylender in the same manner maybe the other side of the engine.
