I am thiniking about buying a Lowe 1860vt tunnel jon boat. Boat weight
is listed at 570 lbs.

I am receiving different dealer recommendations on Yamaha 4 cyl jet
engine size. One says a minimum of 90 HP (60 usable) and another says
60 HP (40 usable) is fine. The one recommending the 90 HP says that it
will take forever to get on plane.

Can you help me?

I had a 16' Alumaweld flat bottom sled with a tired old 85hp
Merc and jet pump. It was ok with a light load but marginal
with more. When that motor died I got a '98 115hp Merc 2
stroke. That was plenty and I never regretted having a bit
more than enough power.
