Hi I have a 290 luhrs with 350 crusader tbi's and all of a sudden the fuel burn almost doubled. I did 70 miles and burned about 120gallons when it should have been 70 gallons. I cleaned the bottom and running gear, that's all fine. Engines seem to be running great. Except my port transmission, it has always spun in neutral sense I got the boat a year ago, but today it slipped a couple times when I floored it and I had to back off so it would catch and keep going. Fuel burn was bad on the last trip to with no transmission issue. Any ideas?
also I should be getting 300-400 more rpm out of wide open
