90 hp mercury.
Bought my boat last summer ran great, put sta-bil in the gas for the first time. After running the engine for about an hour, it begain to bog. We managed to idled back to the ramp and took it home. Replaced gas in hopes it would run ok, but again the same problem. In the driveway with the muffs, runs fine, rev's fine but when put in water and under load it bogs. I have sprayed carb cleaner in carbs and put sea foam in the fuel...still having the same problem HELP........
