Got the answer on FB. Thanks! cant wait to get on the water!

Hi again, all. Thought I'd post a quick update. We took the boat out about a week ago for a test run. Prior to heading out, I poured in two bottles of HEET to help absorb any water or bad gas. At the lake, we had the same problems with acceleration. It idles fine, goes okay at low speed, but dies out when going for higher speeds. We ended up getting it started and were able to drive slowly back and load it on the trailer. A couple nights later, I took off the old water separating fuel filter and poured the contents into a glass jar to see if there was water choking out the fuel system. There was no sign of water, sediment, particles, or anything. So as far as I can tell, there's no water in the fuel. (Glad to know that the filter is working well, tho.) When I went to O'reilly Auto this morning to pick up another Sierra Water Separating Fuel Filter (they can order them and have them in about a day for about $2 more than Amazon), I talked to one of the guys there. His brother used to have a Ski Nautique and Moomba, so he knows the engines and layout a bit. He said that since there's no problem with the actual fuel (from what I could see), the problem has to be in fuel delivery - most likely the fuel pump. He said that if the fuel pump diaphragm is cracked, it could have enough pressure to delivery the fuel at lower speeds. It wouldn't sputter or anything, but appear to be fine at lower speeds. But upon acceleration, when the diaphragm is working harder to deliver fuel to the engine, it won't be able to keep up, and the engine would end up stalling out. He said on trucks with the Chevy 350 small block engine, if there's a problem with the fuel pump (cracked diaphragm or whatever), the excess fuel gets squirted out of the pump as you drive, and it ends up on the ground or somewhere else on the pump housing where it can evaporate. But you can't do that on a lake, so the gas ends up being sent to the crankcase and mixes with the oil. So he said to pull the dipstick, wipe it on a clean paper towel, dip again, wipe again, and then smell. If it smells of gas, then it's probably a bad fuel pump. So I came home, followed the steps and..... It smells a heck of a lot like there's gas mixed in with my oil! I had just changed the oil in our 4Runner (full synthetic, but should have a similar smell to regular used oil), and I smelled both of them separately. The oil from the boat DEFINITELY smells of gas. So the next step is going to be to put on a new fuel pump, new water separating fuel filter, change the oil... and then at some point, I'll get the steering cable (got it from Ron today) and the bilge pump done, too. Thanks for helping out, @Timr71 and @InfinitySurf. I'll keep everyone in the loop as I move forward. I feel like I'm finally on the right path!
