For the guys with straight bottom 1990's Top Guns. I have a 1991 Top Gun, weighted 12,900 full of fuel. With 625 to 675 horse power what size props are you running and what speed and RPM are you seeing. I have Kondrads Drives , 26 pitch four blade Bravo 1 props. I have 555 cuin 630 hp engines. Props are in shop now will get them back next week. What should I expect ?

I'm assuming TRS drives. 26 pitch bravo ones. 74 mph

Bravo1 props won't fit on a TRS.

I'm guessing 28 or maybe even labbed 30's on that and it should run close to 80 with that much HP. I'm not positive, but I think it was the 1993 to 1995's were layed up lighter so they could run in the upper 60's with 502's....

One more thing... Invest in a couple of spare drives!

Forgot to say I'm running new Kondrads drives, 26 pitch Bravo's being worked at this time. 555 cuin 630 hp

OK, having a trans will eat up some HP.... but you should still be mid 70's+

I have a 1995 525 EFI XR gun with Bravo I 26P props. I see 73-74 low on fuel & at most me & my tiny wife in the boat. It is a 71 MPH boat loaded with fuel & 4 adults. Not super fast but a good boat.
