    Whine at idle speed

    Hey guys. Been a while since my last post, but between the cool spring and life, the boat has been kind of on the back burner. Anyway, finally got it in last weekend. Before I did, I installed a new prop using a harmonic prop puller to remove the old one (requires hitting with hammer). Did not notice it right away, but within the first 10 minutes I notice a whine while in gear at idle speed. If I give it some gas, the whine seems to change with RPM and goes away (maybe just can't hear over the engine). My first thoughts were alignment or maybe something as a result of about 10 blows with a hammer to the harmonic puller, and therefore shaft. Also, there are a lot of weeds in the lake this year. Is it possible even without a vibration they could have somehow get inside the cutlass or something?

    Any thoughts? Am I on the right track with the alignment? Can't think what would have thrown if off between last year and this year, except the prop puller.

    Sorry, should have mentioned it is a 2002 SANTE with the Excal.

    My first thought with the sound disapearing with throttle is the belt. 2nd thought would be the packing gland being to dry.

      Good thought. I will check the belt as I did change the impeller. I thought I got it good and tight using the square whole and a 1/2" ratchet, but who knows. Temp was fine, though.

          I had the same issue from the prop, but it sounds like yours is from the engine compartment, right?

            To be honest, I can not say for sure. I had very little time to look into it. I keep wanting to get back to it, but between a 2 week old newborn and our 2 year old, time is not something I have a lot of these days. Oh yeah, throw in a truck that is a POS that needs constant attention, finishing a bathroom remodel, and discovering a leak somewhere in another shower (still need to figure that one out) and time is really short.

            I installed the Acme 644 if that means anything.
