Looking for suggestions on where I should set idle on trailer. 1200ish? Idles awesome on trailer about 900 rpm but, of course, in the water with the impeller lol ad won't stay running, and a moving, loaded boat is not ideal for idle tuning...

I think I?m about 1200ish, (my tach stopped working a long time ago).
Like you said it?s different in the water, under load. Your going to have to set it a bit higher, then launch and do it on the water after it warms up a bit.
Single or dual carb?

You shouldn't be idling your jet boat on the trailer. You are killing the packings and taking life out of the impeller and wear ring.

That makes it a bit easier.
What Joe (Flusher) is saying about killing the packings and wear ring is that they are water lubricated. Running without being in the water kind of like running a bearing with no grease. A start up is ok, but not too long. The packing glands can start to ?burn? and the wear ring could have debris that can mar the wear ring and impeller.

Set it about 12-1300, but had to put a lot more in it on the water (3-4 full turns). Lowest I can get it in the water is about 1200, and that's with a nice lope and over 15" of vacuum.
