Adding to the post with a slight twist. I was asking my mechanic, (whom I trust, experienced and NOT trying to rip me off) about the -in my opinion- abrupt shifting possibly due to slightly high RPM (showing 800 at the tach) at idle and idle in gear. I went with him on a bay test after he recommended changing the 26 Pitch props, which needed recon anyway, to 22 pitch. The scanner confirmed a proper 650 RPM at idle, and the 22 pitch props made the abruptness of the shift a little smoother. At WOT we hit the rev limiter at 4975 RPM. Didn't really get a full MPH reading with the GPS but it was around 53 MPH. (i did 58 MPH on the lake at about 4800 RPM with the dinged up 26 pitch props at time of purchase)
The next step after consulting Mercruiser (mechanic did research said the 496 rev limiter should kick in at 5100) and the Prop shop is to cup the 22 pitch props to back off the rev limiter kicking in, and gain a few MPH above the 53 MPH.
The boat has no Bottom Paint currently, and the mechanic ran the boat with 24 pitch props and he said it ran like #$%@!.
Any thoughts??? I see that Mi3sons is happy with the 24s, and that makes me curious about why the 24s didn't work with my set up.
Mi3sons what is you WOT MPH with the 24s???
