A hooked boat vs clean boat can make that difference.

18 or 19 mph with 25 gdlt on a 1644 gd boat (no hooks) with only me 215 lbs gas and battery. 19 might even be stretching it. 2 people with hunting load i get about 15-16.

Now that is a accurate speed.

Dont get me wrong, when I move up to a surface drive in a year or two, my longtail will be staying to. For some places they are amazing, but I been running one to long for someone to tell me some bs speed. If 19 in a 6.5 long tail was possible, then why would people need surface drives.

I'm running a MB 35 Lt on an F&F 16/52 1/8 hull at around 26-29 depending on the water depth.

I have seen some custom small long tails like modded up to the point of death run in the higher teens but these are almost factor longtails they are talkin about here.

my homemade 6hp lt runs in the teens its about 20lbs lighter than a real 6hp godevil and with the governer removed she sounds like shes about to blow anytime but ima run it intill it doesnt run anymore

what did u do to remove the governor? did u take out the gear or did ya leave it in?

My Mudauber longtail Kit#2 has a 13hp Greyhound or harbor frieght engine. I get 18mph in a 1442 G3.

Bought the boat used for $800. Kit cost $800 Engine $259. on sale

That is what you get when you cant afford a universal joint, 12 feet of shaft behind a boat.
And not 18mph.

I get about 12 to 14 mph in a 16 hp gdlt and a 1644 flat thick hull.
