Default Xl 2000 top speed

Newbie here... I have a 1990 5.0 alpha one that’s getting 35-37 mph at 4200 rpm and I’m told it should be going faster.

    For starters.... the engine could be 'tired' and in need of a major tune-up, prop could be the wrong one (probably needs a 19 pitch 3 or 4 blade), prop blades chewed or bent ?

    WOT with the 5.0 should be around 4800 rpms. Read thru one or more of the STICKYS at the top of the Prop Talk Forum for some additional ideas.

    Recently installed a new 3 blade 14.25 19 pitch turning point as well as a new shift cable. Tune up will be done shortly. Just trying to get an ideal on what the mph should be around.

    Okay. I would suggest that boat should top out in the very high 40's but dont count on the speedo being accurate. Only turning 4200 rpm with a new 19 pitch prop indicates you have other (engine / timing) issues to be dealt with.

    One other thing i just thought of. Have a look at the back side of the tach and ensure that it is set to "8 cyl". If not, do so and give that little wheel a few spins around before setting it. Sometimes a bit of corrosion or dirt will cause them to not read correctly.
