What size shaft?
« on: Oct 04, 2018, 10:08 AM »
Boat is a 1989 19'6 alumacraft.  Main is a 140 looper with a 20" shaft.  Question is what size shaft do I opt for when looking at kickers?

Thanks Mac.  I was going to address this question to you directly but wasn't sure if you were hibernating yet or not.

lol

here is mine.
both 20" shafts.
The transom on mine steps up....but so does the V in the hull.

And when you troll, the hull is lower in the water.

That's helpful Mac.  I'm looking at a 2002 9.9 yam 4 stroke.  New carb.  1100 bucks.

Side note hows your boat go with that 60?  I've mentioned my desire to rid myself of the looper...but it does push me to 40mph when its operational!

Bottom line....I wish I had gone with the 90.
Before I added the kicker and the 2 extra deep cycle batteries (have 4 in series/parallel on that Terova) it was ok.

The hole shot sux.
Ive added a 4 blade ss prop which helped a little.
But its a slug off the line.
That all said, I get 34-35 on smooth water and it is SUPER fuel efficient.
It works, still.....

I violated one of my rules.
Always max out the HP.

Hope that helps.

Thanks

It will be for sale summer of 2021.
Its been very well cared for and <100 hrs show on the hour meter for the main motor.
I will not be giving it away but someone will get a great boat for sure.

I got a 20" on my 21' Sylvan and it still cavitates s a small amount in rough water. But I think with an XL I would have to use a plate to get out of the water enough on plane.

Like Mac, both are 20" shafts.

Thanks Jethro.  Hows that 6 push?  That's a sizable rig you have there!

Funny guy that Mac is... yeah, it's a chunky motor but it pushes the boat really quite well. The boat is heavy, probably 3800lbs fully rigged. I would not want to rely on the kicker to get back to the launch if the main failed, it goes less than 5mph at full throttle. But for trolling 2mph +/- it works well.

That mercury was designed for slow trolling fuel efficiency. But kicker will keep hours down on your main. You two if interested I got 15hp 2stroke 1/100. Long shaft tiller 1986 eveinrude. These are very sought after as kickers that will get you home. Not cheap but one pull starts every time.(with fresh fuel)
$1,000
 I kept it for my boat but the mercury is great. Pm me
