Re: HELP!!

It could be the shift cut out switch hanging up. Usually it's the lower cable going bad. I'm a Merc guy too, but it sounds like that could be the problem. Does it shift hard? J.

Re: HELP!!

The only VP 2 barrel duoprop chev V8 released in 1988 was the AQ211A (305 chev 210hp). You should be able to confirm this by the serial number stamped on a plate next to the starter motor.<br /><br />No shift cut out switch on the duoprop. The cone clutch is a very smooth and reliable mechanism but selecting a gear at 1000rpm may be too much for it, its possible the cone is binding and stalling the motor from constant high RPM selection. Changing the outdrive oil may be a good idea also (10w30 or 10w40 engine oil).<br /><br />Haven't seen electronic ignition on these as standard. The manual quotes idle RPM at 650 and timing at 6 deg at idle. These reading may differ depending on what type of ignition is fitted.<br /><br />You could also try swapping the carbs to see if the problem is carb related.<br /><br />Aldo
