That gearcase would most likely only work on a 1985-1987 3.6 counter rotation engine because the counter rotation powerhead actually spun counterclockwise. I had a CR and SR case. Those cases were slow but bulletproof.

I refuse to allow common sense to interfere w/my boat buying decisions.

Gear case
I have a 1991 gt300 v8 on a 21 foot avenger modified tunnel. It weighs about 1500 less the motor. I'm having a hard time getting it much over 60. It will turn 6000 with four blade 25 but only running 61 on the GPS. I tried 4 blade 28 but it won't turn that more than 5200 at 52 mph. It should be running better than that. Compression is 120 to 125 in all cylinders.
