This weekend we took my 1989 outrage 20 with a 200hp Merc to our summer home which is 34 nautical miles away. On the way there the weather was perfect , on the way backe the seas were very lumpy. We managed the same speed in both directions.
At 3800 rpm (the boat seemed most happy at this speed)we were doing 25knots. At 3500 rpm we would do about 21knots. WOT was 5800 rpm and 34.5 knots.
The boat was fully loaded with four people , a dog ,extra kicker and lots of supplies plus a full tank of fuel.
Do these numbers sound like they are where they should be?
The boat was unbeleivable in the rough water and we had a great time until it started to rain.

Glad the Whaler is working for you. Considering your boating territory, I would strongly recommend looking into the Mills Flying Top canvas set for the boat. It will be worth it's weight in gold. See Rendezvous and Sail-Log sections of this website for photos of the Mills canvas weather protection system. Sounds like you're running over to the Gulf islands, paradise indeed.
The 200 Mercury, assuming it's running properly, should give you about 50 MPH, lightly loaded. If you are indicating 5800 RPM's heavily loaded, your prop pitch is too low. Engine redline is 5600, and I would recommend a 19" pitch, either Mercury Laser II or 4 bladed Offshore, both highly polished SS.
I am fairly experienced with Mercury 200's, both carbed and EFI, and I have never experienced the 3500 RPM resonance you mentioned. Mine are extremely quiet at 3500.

Thanks for the reply . Actually my summer home is on the Sunshine Coast in Secret Cove, not the Gulf Islands.

Secret Cove was one the highlights of my 2 week cruise up and down the BC coast. Spent the night docked at the Marina and had dinner upstairs, last July 3rd. Maybe you saw my 18 Outrage. From there, headed up to Princess Louisa. Best boating in the world if you ask me.

Those numbers are not acceptable at all.
As IHG mentioned that boat should be in the 50 mph range.
That boat loaded as you were, should still get 45 easy.
I'd listen to IHGs suggestion on the prop.
