Need some help with a long list of problems.
My boat has not been running well for two seasons. I have a local boat mechanic winterize it and tune it every year. This year the boat had carb rebuilt but still ran horribly. I drained fuel from tank and replaced with 93 oct no ethanol gas.Changed fuel filter and carb screen as well as plugs then ran half tank through it. Filled tank again. Ran great for two days (like new) and came back two weeks later and it took a 20-30 min to start and ran rough and backfired. It was as if i had done nothing. Hesitation was horrible. Was convinced carb was still no good so i sent it off and had it remanufactured. Installed carb and the engine fired on 2nd crank. Took it out ran horribly again.Still backfired.I noticed water droplets coming from crank case vent as well as more than mormal smoke. Let it idle at the dock for two hrs. Took it out and it ran much better. I was running about 3/4 speed and turned and noticed horrible light brown(coffee colored) fluid spraying out of the vent tube. Back off the throttle and it slowed and then limped into dock.Dont really know what to do.The engine temp and oil pressure were still in the normal range.
Thanks for any suggestions
