Well I finally picked up the boat this past Tuesday. It cost almost
$500. They replaced the plugs on the Force 70 engine, they de-carbed
the carburators, replaced the fuel filter and ran diagnostics on the
engine. If they made any adjustments, I was not informed. I told
them that I would launch it on Saturday and if I had any problems I
would call them.

I launched it. Ran great...until it was time to come home. I was
turning 1300 rpm for about three minutes (in a no wake zone) when it
stalled. I turned off the ignition and tried starting. It just
turned over. I pumped the bulb three times and tried again. It
started. I pushed the rpm to 2200. It ran fine for about three
minutes and stalled again. I pumped the bulb three more times and it
started. I then pushed the rpm to 3800 and drove the boat back to the
launch. On my way home I dropped the boat off at the repair place and
informed them of the procedures I followed while on the lake.

Any suggestions? 89 octane mixed 50:1.
