The last couple of time I had the boat out had trouble starting. Had to put the throttle handle into neutral and "give it gas" to get her to turn over and then idle at these higher rpms for 10 -20 seconds before returning the throttle handle to its normal position...I used to be able to start by choking (pushing in the key while turning) a few times. Have replaced plugs but no improvement. She runs fine once she starts. Any suggestions??
