Tell me how I am doin for speed....

[BAD-HABIT]

Just hoping I can get an idea on how I am doin for speed with my Bird...It's a 1986 F3LS formula says wt is 3600lbs dry. Bone stock original motor with a total tune up got me 48mph. ( All Speeds are per GPS) Going to stainless marine thru hull got me 50mph. Installing the problem child a couple years ago has gotten me a one time best of 56mph Motor is a 358sbc roller motor pushing about 375hp....I am happy I guess with the 8mph increase but man seems like a 3600lb boat should hit 60....Guess I am hoping some people will chime in and let me know I am not doing to bad........Just hate to see alot of the other guys with same hp running 60 or better......Help me out guys cheer me up! Tell me what a great speed I am getting

Throw the gps overboard, and pick up 8 to 10 mph.

Then I would have to go by the spedo...Everyone says theirs reads higher than the actual speed but mine has always ran slower.....

Disconnect the speedo, and drink more beer when you're telling the story.

Not too familiar with that model. Closest I came to that was an '88 223 with a 454 (330). It would do about 60 on a good day. I think it weighed about 4000. So, you should be getting 60 out of yours I would think.

What prop and RPM are turing?

By the way, your boat is beautiful!!!!!! Nice job and nice engine bay.

Well I have gotten my best speed with a 17p attwood ballistic. and a 21p Mirage. Thou the 21p Mirage only got me to about 4400rpms if I remember. I lost about 1mph going with a custom 17p accelerator prop Darrin at Houston hooked me up with. Not sure why I didn't gain the 2-3mph everybody else was getting with the labed props from him. That being said the accellerator from him does carry the boat ALOT better. Accelleration is also improved...I was turning 4800 with the stock motor and the 17p Ballistic. Now I am now turning about 5300 with both the ballistic and the Houston Prop Accelerator.....Motor peaks out at 52-5300...
