I have a 25gdlt and with two people im getting 3480 but out of water i get 3850 is this sound about right for this motor my boat is a 1546 alweld xpress.

With 2 people thats not bad at all.

Well thats good to know, do you know if you can add mods to a kohler 25 or not.

Pretty sure you can mod anything. Never was into the mods so all I know bout dat is what I hear.

I here alot about other poeple doing vanguards that way but it seem they only do it to surficedrives.

no u can do it to long tails they had a guy on here with a stage one long tail dont member who

I dont know if it would really be worth modding a long tail. I mean, ya got 25hp so you cant expect a whole lot more than what ya got. You can spend a bunch of money to get another mph, is it really worth it?

MY two huntin buddys got surfucedrive and they dont care for longtails to much because there not as fast. but i seam to be able to run alot skinny then they do. But that also in sand bottom we dont have no mud knowwere.When there suck im still moveing, laughing me ass off.

Ya i here ya. When the season is over ill put my 30hp back on for the famliy .Because by then are tides are back to normal and i wont need a mudmotor.You said that you have a GTR my buddy has one, with 100hour or so and having lots of trouble with his, how your.

I'm comtemplating something similar now.

I have a 31 longtail on a 18x60 boat. By myself and no load I can get 19-20. With my usual load, I run around 17.6. Would like to be around 20 with a load and 24 without.

I already have a BPS muffler with a k&n filter. These 2 things increased my speed by 1-1.5mph.

Thinking about dropping $700 on the Mikuni carb. Would be a cheaper fix than selling my motor for $2000 tops and then spending another $3000 on a 35 longtail.



BTW a 15x46 is not a good combination with a longtail. You need more length. You would probably run the same speed or more with a 18' boat. Go-Devils fastest boat with a 25 longtail was the 18x38.

Maybe try to pickup a 31 of 35 longtail for $2000. Sell yours for $1200. You'll get alot going up 10hp.

Do you mean put a 31 or 35 on my 1546 boat.

I've owned a 16, 25 and 27 godevil.

I now have a 31. Its a whole nother motor. Alot of torque.

My buddy is running a 35 on a 16x48 go devil boat and he and 1 other person was running 24mph on the gps this week.

Does that seem like its kind of low for a 35 or is it me not knowing what the F@#> im taking about.
