idle out of water
i have reset the tps with candoo and my idle is 1750 in the water now but out of water its around 2000-2100 what gives. is this normal i remeber it being about the same in or out of the water. could it be the iac ?

Should be the same in and out the water. Checked for a vacuum leak? Have you visually inspected the throttle butterfly?

less drag on prop out of the water maybe?

check two things.
1) Make sure the terminals on the battery are tight. I had this problem in my yamaha jet boat.
2) Make sure the injectors are flowing like they should be. A weak injector will also do this. It's more evident when you're at constant throttle at certain speeds when you can hear and see your revs twitch a little.

my rxp is 1780-1800 out of water all day long, this happened after the ecu was installed i reset the tps multiple times its ok in the water. is there a way to test the iac for proper function ?
