I have a 2015 Mercury 20hp with only 10 hours . I couldn't be happier with it.
It has pushed my 1542 tracker topper with 3 heavy 250lb guys, cooler and
Fishing gear 24-25 mph . When it's 2 people I get 28-29. When it's just me
By myself I touch 30. I did change the prop to a solas amita 12 pitch but it
did suffer a bit with a heavy load . I just went down to an 11 pitch solas
Stainless steel . Looking to get an extra mile out of the prop by myself. I have always
been way over the weight limit on the boat and it has done pretty good. Your Lund is heavier
then my boat so if you want to do over 30mph I would go with a 25hp Tohatsu. Try and
get a 2015 and up because they changed the gear ratio went from a 1:92-to 2:12 and
the motor is a beast. There is also the new 2017 Yamaha which is the lightest 25 by far and
its cheap. I wouldn't even look into Suzuki . I'm all the tests I've seen, they are running last.
But for the 20hp engine the best would be Mercury or Tohatsu . For 25 the best would be the
Etec, or Tohatsu if you want the best power and top end. Do not look into the Mercury 25 because
they still have the 1:92 gear ratio. If you want a four stroke 25 I would get the new Tohatsu. If you don't mind a 2 stroke , get an etec 25. Just my opinion.
