I'm looking at an '89 Champion Fishunter 26 Pilot House with AD41A engine that is listed on Bloodydecks.

A very knowledgeable boating source tells me these were built off the Blackman 26 hull with modifications to the Express top side to turn it into a open back pilot house. He even knew the name of the builder. The other obvious mod was to raise the gunwale around the cockpit so that you have fiberglass thigh high as oppose to just the railing.
I've been on the boat and it's a Blackman as my source says. You can see the Express lines inside the pilot house.
Engine has 751 hours and looks it. Fires right up, but I only observed it at idle. Owner says it's a very heavy boat, claims it weighs 10,000 lbs. He says the cruise speed is 12 knots at 2900 rpm, but he "babies it". He says that WOT is 3500 to 3600 rpm. I have the manual and that engine should run 3700 to 3900 rpm at WOT. It also can be run at 90% of WOT for cruising. I asked him what props and he wasn't sure, but thought A2 or A1. I have yet to sea trial it which should be very revealing.
My main question is what do the Blackman 26 fitted with the 41 series engine and DP290 drive cruise at? Full of fuel? Half full?
I have the AD31A in my Blackman 20 with the DP 290 drive with 1.95 gearing and A4 props. I'm heavy with a 42 gallon bait tank and stainless t-top. Full of fuel (80 gallons) I run 18 to 19 knots at 3300 rpm with the engine temp at 190.
