just got this boat/motor. it ran poor from the start. loads of water
in fuel seperator and did the following.
- dumped old gas
- replaced all fuel lines, from tank thru to carbs
- cleaned and rebuilt all carbs, including new high & low speed jets
- new spark plugs ( gapped correctly )
- new spark plug wires
- rebuilt fuel pump
- replaced one of 3 coils
- installed tach
- compression check ( all with 10 of 110 )
- checked timing, ( is it really just stop screws )
got boat to start well, idle well, run well up to 4000 rpms then it bogs down.
squirt pre mix into top carb at wot and motor would jump up to 5500 rpms.
same story with holding in primer solenoid. jumps to 5500 rpms.
- cleaned all 3 carbs again. this time soaked in mineral spirits for 20 mins
and worked them with a toothbrush. blew them clean with compressed air.
put it back together, started motor with muffs in driveway, a little hard to start but ran okay at idled to 2000 rpm for a good 10mins
took boat to water, backed it in, lowered motor in water. motor would
not start. waited 15 mins. shot some starting fluid into carbs, motor
started. ran on trailer in water for 10 mins, then pushed her off
and headed out. got up to 5500 rpms for about 30 secs, then she died.
got it started again, and limped in at 1500-2000 rpms. lots of coughing,
gasps and choking the entire way. anything over 2000 rpms she'd die.
my current thinking is, fuel problems are now solved but there is now
a spark problem. i have ordered a new powerpack and will install it
and test again this friday.
my question: - am i grasping for straws with the new powerpack, does it
really seem like there is a spark issue, what else should i look for, consider,
do or test ?
