I am having issues with a boat that I just purchased. It is a 1997 Princecraft that had the original OMC motor swapped out for an '88 yamaha 130 ETLG. The previous owner said the oil injection went out and blew the last motor, so he had this one installed. He also had disconnected the oil injection and it is premixed (If I had all the parts I would hook the oil inj back up). When I first bought the boat, there was hardly any fuel in the tank and the primer bulb would only gurgle. I added 5 gallons so that I could run it in the driveway. It was hard to start cold, but would eventually fire and idle just fine. When I first took it out (I put an additional 10 gallons in), it started just fine and I idled out past the no wake zone and slowly began to throttle up. It took off fine at first, but when it hit part throttle, it bogged really bad and died. It didn't want to start right away, but after fishing awhile (used the trolling motor), it would start up again (ran best when choked). For the rest of the day, I could only get around on part throttle (below 2000 rpms) and if I tried to give it too much, it would bog and die. Even after going around at low speeds it would sometimes bog and die. When I got it home I pulled the carbs and cleaned the inline filter on the engine. When I pulled that, I noticed the fuel looked a little off and knew right away it had water in it. I drained 6-7 gallons of fuel out, and was able to get a gallon of water after it settled (added starbrite enzyme treatment to the tank afterwards). After that the fuel ran clean out of the line. I re-installed the carbs after I cleaned them (they didn't look that bad) and when I started it in the driveway it started right away and wasn't cold blooded at all. I also checked the compression (~125-135 on all cyls), and I have spark in all cyls. Fast forward to this weekend, I took the boat out again and it is having the same symptoms. It does not want to go past part throttle and it eventually dies when putzing around. I was able to motor around much more than last time, but it still would bog and die. It seemed like sometimes it took excessive amounts of choke to get it to start, and other times it seems like it had plenty of fuel and didnt want the choke at all. It would also run a little stronger at times, but would die sooner when I did that. When I got home a drained some fuel to check for water and found none. I plan on replacing the fuel pump and probably the fuel line connector just in case it is pulling in air. It seems to leak when I first hook it up, but seals fine after I prime it and let it sit. I also checked for kinks in the fuel line and open that gas cap just in case there was vacuum. Te me it seems like it is not getting enough fuel and doesnt want to run under load. Other than the things that I mentioned I am replacing, does anyone have any other ideas? If I did not give enough info please let me know what else to add.
