I have a 2002 Classic with a 15hp 2002 Johnson 2 stroke.
I am getting 21MPH at WOT out of the boat with two people, 90lb dog and fishing gear.
The speed was confirmed by two GPS so it must be real.
I guess the total load at 600 pounds and that is what I would expect to be normal in the future.

Is this normal?
Do I need to get a Tach to check the load on the engine?

I am getting a spare prop and just want to know if I should just match this AL prop or upgrade to a Stainless prop.

Thank you for your help.

Get a tach, don't guess, it's the best way
to make sure you get the most out of your outboard.

With a guesstimated total weight of 800 lbs (boat, motor, gear, people)
15 hp returns about 25 mph per the calculator.

I GPS'd my LT25 last week with my Johnson 15 2-stk at 23.8 mph. Two guys and gear. I was ecstatic!! Probably 150 lbs less, though, without the dog and I only weigh 148, my buddy about 175. Still, I'm looking to improve this speed a bit. Not so I can run WOT all day, but to run as fast as possible at about 2/3 throttle and use less gas. Don't know the weight difference between the classic and the LT25. My LT has low front deck and is pretty much a frugally rigged boat.
