Motor speed

Ideas on what should the average speed be for a 25 HP tiller outboard. It is a 2000 Nissan set on a 14' Ultra Jon.

From other boats I have been in simular to yours,I'd say 15 to 20 maybe 25mph.Depends on weight,loading front to rear,and water conditions.

I'm getting a solid 28mph (GPS) on a 14' Alweld with a 25 4-stroke Yamaha. This is with a full load. It will hit 30 on rare occasions.

I would say 25 - 32.

I have a 96' johnson 25hp on a 14' jon boat and avg when i cruise around 22- 23 mph. That's a good speed you'll probably get the better gas mileage on rather than having the throttle mashed the whole time. I've had mine up to 27.5mph but i haven't had it on a calm lake yet. I just got it about a month ago. That's hauling *** for a small jon boat though i think. For what it is and what it's meant for. You can't beat them for the price.

Thanks guys, I'm running about 28 MPH @ WOT and I'm very satisfied.

That's better than I ever got.Good work.

It's worth playing around with different props if you can find someone willing to let you borrow a prop that fits you motor. I wasn't wanting to increase my MPH, just my fuel economy.

Just put a 9 7/8 x 13 pitch SS on the yamajammer 25hp and I'm topping 32mph GPS with just me and a solid 30 with two people. It would hit 31 but wouldn't maintain it. I've also boosted my MPG by over 10%.
