I should push 75 this year with a little fine tuning. There making just about 500hp. I cant wait to see. Keep me posted how u run with ur new power.

Nice boat.

Just thought I'd mention in '88 your power options included either 425 TRS or 454 Magnum 365hp Bravo.

NO argument there. His is the speed benchmark for all Panthers.

viper???? his is a standard '87 panther that originally came with 365's.

drasticcaddy I believe the 365's have GM rectangle port heads
