you shopuld see at least 60mph. I run 23p mirages and actually get my best speeds trimed all the way up. one guy(290lbs) quarter tank and 1-2 footers 68.5 gps. I also make about 330 per side, The big difference is I do not have silent thunder. this saves a ton of weight. I only have a teak platform and not to mention this puts the exhaust right out there.
Lose some of that fuel and trim it up in 1-2 footers and you should see the low 60's.
If you have cleavers on it lose them. they give a good top speed but you loose cruise and midrange and Gas milage

I had a '87 242-SR1 with twin 350 mags. factory rated at 67, but best I ever ran was 65. Boat needs a lot of trim to get it loosened up to run. Heavy boat that will run descent when it kicks up. Great package.
I would check the gimbal rings out. The alpha drives on them '87 weren't counter rotating, a tie bar was an option, and I've never seen one with external steering. If it doesn't have a tie bar, I would suggest adding one.
