Sounds about right what you're getting for speed. I have a couple buddy's with 600's in 38 straight bottom older cigs, if they hit 70 the stars aligned, light on fuel, good chop, cool air, etc. Sounds like your speeds and Full Forces speeds are where they should be.
Lately on oso and facebook, I've been seeing some ridiculous claims. Guys claiming 80+mph in Cafe's and straight bottom guns, with 600's. Mid 80's with 700's in straight bottom top guns, and so on.
I'd like to see some of these guys speedo's and dyno sheets. These are heavy straight vee bottoms with a sharp deadrise, not pad bottom boats. I'd take a old straight bottom gun in a minute if I could run 85mph with 700's, or a Cafe with 600's and see 80+.
Posting speed numbers used to be about helping other guys to get an idea of their setup, or what "could" be done if they upgrade their power. Now, its all about some elementary bragging right. Nobody's impressed by lying about your 75mph top speed, and calling it "80". Not when we live in a world where 100mph vee's are a dime a dozen.

guys crack me up with posts on speeds at times...
Any older boat in 70-80MPH range is a good time and impressive to me....

For me its about cruise speed. I dont push it hard but will post numbers when weather breaks. My boat is kevlar with the hook removed from the bottom.I did a search on OSO seemed like someone put alot of R&D into the boat for setup.

Mild,
Some of the numbers you're quoting might be slightly high, but I have some friends with 1994 straight bottom TG's. I know for a fact the boat with 500 EFI's (which I believe dyno at around 470hp) and bravos runs 69-71 depending on load and the other with 700's and TRS drives will run 82-83,. With "faster drives" I'm sure the 700 boat would run 85. A straight boat TG with 600's and bravos should run around 78 or so. With perfect conditions, saltwater, no passengers, and extrememly light on fuel, these numbers would no doubt be a little higher.

When I bought my boat, I was seeing consistent 66 at 45-4600 RPM at 3/4 of a tank of fuel, propped wrong due to the previous owner swapping the 1.5 drives for 1.36 drives. By every account from previous owners the boat will run 67 all day when propped right and touch 69 if the stars align. What is interesting is this is with 425 horsepower. The only difference I can see is when this boat was converted from a TRS to a bravo drive the X dimension was brought up quite a bit. I have also noted no porpoising at any point. The only downfall is some minor blowout getting up on plane, but you can power right through it with no issue. I wonder if running shorty lowers on a factory bravo setup would result in worthwhile speed improvements. I have already swapped back to 1.5 drives for next year and will be sending the props to BBlades to see if we can get the slip down from 16% a bit and squeeze a bit more speed out of it.

Went out yesterday pretty rough chop 35 mph wind etc etc. Boat flew over the waves neutral on tabs. At 4000 rpm Gps 66mph at 4200 68 mph. I think 82-85 with 4 blades is achievable. I am spinning 5 blade maximus 27 no diffuser ring. 1;35 ratio. motors are 700-750
For me its about cruise speed. I dont push it hard but will post numbers when weather breaks. My boat is kevlar with the hook removed from the bottom.I did a search on OSO seemed like someone put alot of R&D into the boat for setup.

At least your slip numbers make sense. I see some guys post speed numbers up, where its physically impossible to do. Like running 90mph with 26p props and 1.5 ratio drives, at 5400rpm. It cant be done.

I am saying it wold be RARE case.... true dynoed HP, basically what we are saying is most guys "claim" speeds and HP....drives play a huge role also, at the same time drives like 3's take more HP then a TRS to spin...so it really depends....
