Suzuki 140 on a 1974 19-6
« on: May 21, 2017, 05:30:01 PM »
I just installed a Suzuki 140 on my 1974 19-6 mounted on a Bob's setback bracket with a Bob's Jack plate mounted to the setback bracket. Same setup that held my Johnson 150 for 6 years.



I started with a full tank. Filled up my 47-48 gallon tank, full cooler, my wife and I in the boat.  Here's what I have so far:
23 pitch stainless prop. 3 blade. 
5800 RPM top end runs about 41 MPH (maybe 42 MPH) trimmed nicely. Jack plate up a bit, motor trimmed, and trim tabs (Lenco) down slightly.
3800 RPM to 4000 RPM runs around 27-28 MPH. 
I ran about 82 miles yesterday (mostly around 25-28 MPH) and it ate 17.6 gallons = 4.6 miles/gallon.  I'm happy with that. 
I definitely lost my hole-shot, but love how quiet this engine is.

A 4 blade might help the holeshot and let you run a little higher to gain the lost top end?

How does it float with a 140 4 stroke, jack plate, and setback?
The reason I ask is I had a 19-6 with yam 115 4 stroke on a jack plate and the scuppers sat well below the waterline. I thought I might have had wet foam in the stringers.
Do you have any pics of it floating?

Having your tabs down as you jump out of the hole will dramatically decrease the hole shot time.  Raise tabs as you get on plane.
