    Being a jet, the usual problem of too much prop does not exist. Look at excessive weight in the boat or bad compression. I'd start with a compresssion test.

    Right. Did it plane before? Did you just now acquire the boat? Any history on it?

    What do I know about jets anyway? I weld skegs and fix props. Did I miss out on some information. This conversation is like talking to a doctor about my high blood pressure, but his nurse hasn't checked it yet. I'm going back to Evinrude and Johnson forum, brothers.

    What is WOT rpm? If you get real high rpm you need to check clearance between the impeller and liner.
