    340 (496) 8.1 RPM range with props?

    A few years ago I had my props re-pitched because I was above my WOT range of 4200-4600. I was at 4730 so I ended up going from a 18x21 with a .075 cup to a 18x22 with a .075 cup. After that I was at 4620 for some reason and gained like 3mph. So last year I had them go over the props again and...

    Would a prop too thin..

    34ft Sundancer prop?

    I'm in the process of choosing a new/used boat I'm really leaning toward the 2003-2006 34 Searay Sundancer with the 8.1 Inboards. I was set on the 34PC Formula, but the outdrives are steering me away docked in Saltwater 6 months at a time. My delemma is speed and fuel savings vs reliability and...

    2001 Mercruiser 5.7 TBI tach wire location?

    I'm looking for the wire to tie into so I can verify with another Tach that mine is working correctly. The reading I got off the - side of the coil seemed to be off by 400rpm with the last tach I tried. Is there a wire in the harness that I can tie into? I can't seem to find in in any wire diagrams.

    RPM question?

    Should you be able to achieve the same RPM in both of these conditions at WOT? Does this sound about normal? 1 - 5am FLAT CALM...2 people I was able to achieve 4400rpm. 2 - 1pm CHOPPY, 3 people, and a filled 20gallon water tank I was only able to achieve 4000rpm.

    What pitch prop are you running on your Cruiser?

    Just wondering what you guys are running. I have a Monterey 262 Cruiser, 5.7 260hp, Bravo 3. The prop from the factory came with a 26P. I bought this boat last fall and is in the water now. I feel it is over proped. I ended up going to a dual 4 blade 24P props and am dropping them down to 22's...

    Prop timing?? Pics

    I'm getting a decent vibration when my drive is trimmed all the way down/in on take off. As soon as it starts to get on plane and I trim it up a bit it goes away. I don't know if this could be a prop problem, but I figured I'd start there. I've been thinking about my props though. When I put...
