200 yamaha cutout

[bryami]

Have a 1999 200 Yamaha Saltwater EFI, starts and runs well. While running under load ie. waterskier, engine will shut off after 20-60 sec. Will instantly restart. Fuel filter is clean, new oxygen sensor and a confused local mechanic. When not at full speed and no load engine will run constant. Any suggestions?

Re: 200 yamaha cutout

wonder if you can shoot some mix in th intake there while pulling a load and see if it will help? other than that compression and spark quality? those three things make a motor run.
