Merc '94, 40 HP ELPTO, Max RPM's?

After a couple years in storage I thoroughly prepped my boat and took the family for some rides on Lake Winnisquam, last week. The motor sounded well but did not hit the speeds I expected and seemed quieter than I expected at full throttle. Some of my passengers were a bit heavy but I've had similar loads in the past.

Fresh fuel. New hoses. Filters are clear (see through). Connections are tight. No crap in carb bowls. I'm planning on selling the boat so I've been spending a lot of spare time on it. The family tours were just a fringe benefit of that work. It was not just a "shake off the cover and go" prep.

I'm going to hook it to a test-tach and adjust some of the settings. Does anyone here know the maximum RPM's for this model of motor?

Thanks in advance!
