"1987 340 searay sundancer with 350 crusaders/velvet drive trans.1000hrs.
first use of the day boat will plain and run fine.stop for 10min or 5hrs.
restarts fine,idles good.starboard engine will not go above 2800rpm on next plaining attempt.some times after a period of time engine will catch up and equal out.if you push the throttle all the way ahead it will come up to 3000 max.once thisyear developed miss at 3400rpm.stopped and idled boat for a few miniute and boat came back on plain and ran fine.i had this problam 2 years ago and adjusted the points and timimg and all was good.the boat will also feel like it is missing and surging at 1500-1800rpm.what i have done.
new points and cap,reset timing to 10 deg.
check and lube springs and weighs in distributer(there is rust on weighs and spring but are working)i have checked with timing light to confirm advance of upto 28deg. when accelerating engine.are they sticking when engine warms up??
swop coils from other engine.
replaced fuel filters in carb and water/fuel seperates inline.very small amount of dirt in filter in carb.
check anti siphon valve.(missing)???
before i go and spend more time and money i though i would see what you guy's thought as you always seem to have great advise.
i am looking into ungrading to electronic ignition this spring as this will eliminate any distributer or spark plug wire issues.i will also be replacing the spark plugs and fuel filters again.any thoughts or similar experiences."
