I've narrowed it all down to the pump. After a cleaning, performance
was much better. It was bogging at WOT, but recovering and staying
with a little help from the choke or bulb.

So if anyone could advise... Will a rebuild kit solve the weak pump
problem? The rubber diaphram seemed flimsy and stretched a bit, but
I've never seen a new one either. Otherwise, if I need to get a new
pump all together, will any VRO work? I've read that the newer ones
are better, so if they work I'll go for one.


Here is a link to the VRO story that may help you understand the system.

Thanks! I just got back in from a long test run. Now we're at Carb
rebuilds, new plugs, switched to Johnson brand oil 50/1, cleaned fuel
pump and replaced fuel filter. For the first time ever since I've
owned this boat, it will take WOT !!! Very nice for a change. I'm
still going to rebuild the fuel pump side since that seems to have
been the problem all along. Other than that, generally running nice
and smooth now ( still occasionally bogs if I throttle too fast, but
catches right up in a sec ).

Good God man, what are you doing here when your engine is running..
dope.. go back to the water!

If you want to take a easier route, I bought a new VRO pump
for under 100.00 on ebay. Nice new and worry free.
