My friend has a 93 yahama pro v 150 with a new power head that fouls out all the plugs every other trip to the lake. Thanks for any info on this problem.

Just a guess, engine running to cold, wrong sparkplug, float/float valve in carb, propped wrong, weak ignition system. New powerhead may just need link and sync.
Help somebody every day, if you can.
Not sure which models, but some Yamaha's use 2 different ignition systems on a same model size. The plugs are totaly dedicated for each system, and will not interchange. Be absolutely sure you have the right plugs to start with!!!![]()
