89 Mercury 150 Blackmax vr4 starting issues

[EarlyCuyler]

I’ve recently redone all gas lines in the boat and fuel/water separator. It starts wonderfully in the mornings before I head out to the lake and preforms well for about a hour or two. Then after it’s been started and ran for a while it just won’t start I can try cranking over and over but acts like it’s starved for fuel. I had to get towed in 5 miles today. As soon as I got to the boat ramp I cranked it a few times and started right up. Could it be the coils, plugs, carbs? Please someone help me with this. It ran great at 54mph trimmed up at 5k Rpm. Hole shot was fast.

I would get the battery load tested.-----Then pull starter apart for inspection..----Inspect battery cables.----All " no money spent " checks to do.

are you usin' tha enrichner when it gives ya tha problem?

 

[EarlyCuyler]

I’ve changed all batteries from 2 (6v) to 3 (12v) and new wires. It almost feels/ sounds like it’s not getting a spark to fire it up. I do use the choke/enricher when I start it, could that be fouling my plugs or flooding the motor?

Take the starter apart for inspection !-----If motor does not turn fast enuff there will be no spark !!
