I recently bought a 97 gtx from a guy that had let it sit for years. I replaced the old gray fuel lines right off the bat. Rebuilt the carbs. New battery. New spark plugs and wires (cut 1/4" off before installing boots) . Cleaned the rave valves. Drained the fuel tank. Replaced the oil injection lines. Installed new fuses and cleaned electrical connectors. It runs fine out of water (has a rough time starting after sitting for a day or so). Starts up and idles at about 3k. When I get it in water idle stays around 1500. As soon as I take off and hit about 3k rpm it bogs down and wants to stall out. I checked the rectifier by disconnecting the red wire and I get the same result. I'm left with checking the fuel baffle and making sure the fuel lines are tight. Other than that I am at a loss for what is going on. Ski only has 124hrs on it so i doubt the rotary plate is worn but might be worth a check. Could aftermarket diaphragms in the carbs make a huge difference? they seemed comparable to OEM.
Ps. Carbs are adjusted to manual spec
fuel baffle is in good condition
compression is 141 and 145
