buying a 27hp kohler long tail this weekend with new prop running it on a 1648 war eagle i usually hunt with two people boats been strengthend and re braced and tall transom. what you think it will run

I think you're doing this backwards - Run it then tell US how fast it went so we can all learn from your setup

13.6

im trying to figure out if i want to run it before i buy it cause im getting told its not big enough. but the 27hp is good from a 16ft to a 20ft boat

I'd say run it

It will push that boat just fine. My best guess is 20ish light loaded, and 16-17 with 2 people and gear.

If the WE hull has a high transom, like you stated, it won't be very fast if you are using a standard 72" shaft....if you intend to keep the boat/motor for some time you may opt to cut down the transom to 16" and get better performance. I run a 27 MB Kohler LT on a 1648 2004 Grizzly (.100 gauge) short transom hull. I get 19.7 by myself, 17.5 mph with two hunters and all the gear.

thanks guys very helpful. guys in another forum were saying 5 to 6 mph and it worried me. never ran a mud motor before. i found a kit for my motor for a tall transom dont know how much it will help it out

you guys are very helpful im anxious to see how it does and have my first mud motor

Another vote for 13-15 mph

If you're worried about speed you better run it before you buy it.

I've owned a 9 hp, 18 hp and now have a 25 hp longtail, I didn't run any of these for SPEED but they got me where I needed to go.

If you get 17 to 20 out of your boat solo you'll probably drop to 15 or less loaded.

What kind of kit did you find, have you ran it yet

I run a Beavertail with 27 kohler on a 15'6" Gator Trax. With just me it's 21mph and loaded down with 2 guys & dog about 15. I'm sure a lighter hull would get 23-25 but that gator Trax hull is 375 lbs dry weight

I run a mud buddy 27hp kawaski longtail on a 16x48 grizzly tracker and get 17-18 with me (140 lbs) and about 15-16 with two or more people.....i have a short transom

I think you should get 15 - 18 mph

Im running a 23 on a G-3 1548..and getting 18.2 MPH solo light load little smaller boat little smaller motor. I imagine with the 27 and a bit bigger boat you should be getting in the same ball park.

I have a 27 Kohler on a 1548 Jon and got 22 mph with 2 people but no gear.
