J-Craft

[speedking]

just bought a 16 foot j-craft, want to put a 115 merc tower of power on it. any one know how fast it should go with the right prop?

[chris_lacey]

That "J" has a very flat bottom. I would expect it would turn a 19-21P at mid 40's mph with the 115. Typically the 17's ran low 50's with inline 150's and the 19's ran 70 ish with a 225.

i have a 1980 16' "j" , any one know what it should be worth roughly in mint cond.? ( boat, good trailer, and 115 merc)
thanks

Where is the boat located? Has it been recored, new floor, transom? I'd guess 6000-7000 if it really is mint. You could track the Boat Trader for a while to get an idea of pricing.

Chris's speed numbers are probably accurate. You can do better with some setback and propping, but most J's are set up for skiing only.

[EXSTREAM EH!]

Chris and Dave are both right on the money! I had 17' with a 150 merc on it set up on the second hole up and a 24 three blade she would run right about 52mph. She was a very ruff ridin and wet boat. See if you can get a hold of FLATOUT he can set you up right the first time!

EXSTREAM EH! Gone

thanks guys

[speedking]

does anyone know what pitch prop would be best for skiing on the 115
on the j-craft? any help is appreciated.

[David]

I'd start with a 20" Laser or Hi Five. That would probably give you around 45 mph max, and a good pull out.

It should be possible to find a used Laser pretty cheap.

[speedking]

are lasers and hi fives props? never heard of them before, what would be reasonable price?

[speedking]

ive never heard of a laser or hi five, are they ski props? what would be a reasonable price for a used one?

[David]

High fives were/are made by Merc for skiing.

Lasers are cheap and should work pretty good for skiing, and OK for speed. Look for used props here, and at BBC, and on Ebay. http://www.bassboatcentral.com/props4sale2.htm

You need even pitched Laser and High Fives. The odd pitched Lasers won't fit your lower unit.

$150 or less should get you a nice prop.
