How long to reach top speed

[bgreene]

What's the easiest way to measure REAL rpm - what's a digital tach and how hooked up ?

By my count it takes about six or seven seconds to reach top speed with my sweet, never-rebuilt 1989 Evinrude 200XP, but you be the judge. I shot this little video at last year's launch:

[For unknown reasons I can't upload that video to the V20 site, but for anyone who can get around the problem, feel free to do so.]

You hit a small wake and cut the power ?

Wanted to see the full speed, trimmed out, maximum performance with your comment to confirm speed and rpm ?

I watched the video, and now I want a refund !!!

I just found him a 200 mer yesterday on crigslist he was going to pick it up!

Bgreen - that's the only holeshot video I had on hand, but I'll try to do a more extensive one this season. Can't wait for spring launch.

My V21 may hit 100 mph, maybe more off a cliff, but I'm conservative and don't want to push it that hard...

I'm at a loss here....

13.75x17 ss prop, 13 7/8x15 aluminum prop, 13.75x13 ss prop

You say all three of these props gave you the same RPM's at WOT? Comments about aluminum being different than SS notwithstanding the two stainless props are 4 inches of pitch different, they should give you way different RPM's at speed.


The tach sure seems suspect, if not something is surely wrong.
