1969 V143 Jet Flight Engine considerations
« on: February 27, 2021, 05:25:18 AM »
HI,
i just bought a 1969 V143 Jet Flight in great condition without engine.
I have a Mercury Classic 50 here and a 90HP Tower of Power.
my feeling is that the 90 is too heavy for the boat. All pics I found show engines between 50 and 65 HP.
Would be interested to get some first hand recommendations.
Thanks and best
Achim

Not sure what the label plate would indicate for max HP, maybe Gregg has a brochure. I would take a SWAG and say around 60hp is it's labeled max hp.  Difficult question really, if you put the 50 on it, you'll always be wondering how much better it would perform with the 90.  I suppose it comes down to your intended use, and maybe your insurance carrier's stand on exceeding label plate specs?  Since I do my own rigging, I'd give the 50 a try, then maybe the 90. If you're having a company rig it, will they even consider the 90?  Nice looking boat, I always like them with the split windshield.

The 1971 catalogue says "rated up to 65 hp".. but I run a 150 on my CV 16 and that is perfect.. IN this case the weight difference between the engines might be the issue.
any 143 owners here?

That's a very nice V143 !
Charts I have lists .. 
1974  Merc I4 50 HP / 43.8 ci. at 173 lbs. without tilt & trim.
1974  Merc I4 65 HP / 49.8 ci. at 183 lbs. without tilt & trim
1974  Merc I4 85 HP / 66.8 ci. at 234 lbs. without tilt & trim
1974  Merc I4 /115 & 135 HP / 99.8 ci  at 273 lbs. without tilt & trim.

The 1988 Merc I6 115 HP is 312 lbs. with tilt & trim

Most Johnson / Evinrude's three cylinders (50 thru 75 HP) motors are about 250 lbs.
Most J/E V4's are about 310 lbs.

What year is your Merc 90 HP motor ?

You can find the Glastron P.I.G.'s here, with some HP to speed ratings.
Your V143 is very lite compared to the "Aqua-Lift II" hulls.

Thanks a lot gentlemen,
the 90 is a straight 6 Tower of Power from the early 80s (need to check the number)

I would think the old johnsrude in-line 3cyl would be a good motor. Just like the picture.

Hi ars71
I have a 1961 Jetflite powered by an Evinrude Starflite III rated at 75hp.
I've run it since I bought it new in 1962 with no issues.
Needs the right prop to pull skiers.

PS The 2017 Glastron meeting should have pictures of the boat.
