Hi all and thanks in advance. I need to replace my VRO Pump and was wondering if an aftermarket one for 200$ or should I bite the bullet and get an OEM for 600$ it was just replaced 2 years ago with the 600$ OEM pump and not sure why it failed after 2 years. Any advice is greatly appreciated.

What testing / inspection have you done on this 2 year old pump?---Perhaps test run with another portable tank and hose.--How did you determine it is KAPUT again?----The pump is driven by crankcase compression.----There could be issues with that.------Note---In my opinion these pumps are simple to take apart for inspection.

I've had the carbs rebuilt, and the mechanic went through and set the timing, replaced spark plugs. It starts, smokes like it has never smoked before. When I try to throttle up it bogs and dies. We have changed all tubing and he suspects it is the VRO that he actually replace 2 years ago. Spark, compression is all good. Fuel is new, replace fuel pick up tube as well.

Did your mechanic check CRANKCASE compression?----If $$$ are not an issue then put on a new VRO and test run.

Make sure you do not have any air leaks into the gasoline lines. If air leaks, from say, the main strainer, the VRO pump will pump more oil to compensate.

I would hook up a gallon of gasoline directly to the fuel line that feeds the VRO pump as close to the pump as possible, and retest.

To answer your question directly, no do not use aftermarket stuff.

Rebuild it...fuel diaphragm only most likely... But do the other things first.

Question, if your mechanic diagnosed this, why didn't he just fix it?

Im not working due to back surgery and can't afford to replace it yet. I found an aftermarket one for 150$ with a 5 year warranty i might try.

Yes, it's definitely a lack of fuel issue.

yeah , if the genuine one only lasts 2 years why not .
I just top to bottom rebuilt my Tohatsu M18 and the only genuine part was the shift shaft bushing . Bit of an issue with the Chinese carb ( easily solved ) but apart from that brilliant

If your healthy enough to inspect it you may find it needs much less than $150. Also depends on your mechanical ability. Inspecting cost nothing.

But regardless of your issue, having a bad back and boating don't go hand and hand.

I'd wait and do it right. Always worked best for me.
