I currently own a 95 175ZX Skeeter with a 175 Johnson FastStrike. Ive had a loss of aprox. 5 mph top end a some hole shot. Prop has some minor ticks ; getting it fixed while we speak. however Ive noticed a drop in rpm's at top end from 5800 to 5400. ASny suggestions what could be causing this and what steps should I take. Alsop my alarm came on twice the other day. I shut her down and restarted. She ran fine for awhile; then did it one more time; and ran fine after that. Figured it was a air lock from trying to get on plane. Any suggestions appreciated. Carl
