Author Topic:   Minimum Horsepower To Plane `16 Currituck?

I know that it takes 35h.p. min. to plane a `17 Standard(850lbs.) with light load according to the brochure. Does anyone know what the min. horsepower is to plane a `16 Currituck(500lbs.) with light load? I would think it should be less than the `17 Standard do to the 350lbs. difference and the wider runners on the `16 Currituck? I see alot of very good condition 50h.p. engines for sale. Please comment-Jack Graner.

I'm sorry Jack, I couldn't resist --- the devil made me do it heh heh -- since it's all in "fun" (as you stated on your Award post) is that with YOU in the boat or out? chuckle --

Tom, I think with me out a 9.9h.p. will do, with me in, AH, probably a 150h.p. Ocean Pro(smiley grin). Good show Tom, I really set myself up on that one! Smiley regards-Jack(Jake And The Fatman) Graner!

Last summer as service manager for a marina, I helped set up a 35 horsepower 3 cylinder Johnson on an older Montauk. It replaced a 2 cylinder 60 horsepower Johnson that had blown its lower unit. The Montauk belonged to an older gentleman who just wanted a new cheap engine that would get the boat on plane. We had a leftover 1997 35 with power trim/n/tilt so he got it cheap. The only prop available at delivery was a 14" pitch 4 blade aluminum OMC prop. With this prop and over 400 pounds of men aboard the boat popped right up on plane and turned 5,600 rpm right out of the box. The speedometer in the boat showed 30 mph, 2 mph slower than the 60 was with the same speedo. It seemed too good to be true and I would wonder how it could happen if I had not been part of the team setting up the boat.
Just to point out how variable motors can be, I looked at a 1993 GLS 13 this summer with the same motor on it. It had a 12" pitch 4-blade prop, turned 6,500 rpm (ouch) and showed 26 mph on its speedo. I lost any interest whatsoever in an engine that had been consistantly over-revved by that much. I sure did wish for a GPS on each of these boats to verify the true speed.
Jack, your choice of prop may be as important to you as the engine you select to purchase. Dave

LWL, you are so right about spinning the correct prop!! All the power in the world won't make up for a mis-matched prop.. The prop is the single most important item in setting up a balanced rig... don't think so?
Just take the prop off and see how far the boat will go... :).... Clark. .. Spruce Creek Navy
