First Ride 20' SF Rehab

[Normagain]

Just got my boat wet for the first time after a year long rehab. I thought I would put this in the performance section since I have some data on the boat with a Yamaha F115 and Solas Amita 13 1/2 X 15 prop. I actually hit 6000 at 37mph when I trimmed the motor up until close to breaking loose. Just me in the boat with 40 gallons of fuel. Still need a few details like putting in my lean post and bait tank, fabricating a console door and anchor locker door, plus some trim around the gunnels. I'm pretty happy with the performance I am getting but may try a stainless in either three or four blade. My options on props are a bit limited, the Yamaha is a lefty!

Nice, congrats. Those are pretty good numbers, keep us updated on other props.

Thanks, it might be a while as I have a few other priorities having decent performance. I might try a four blade aluminum pretty soon since they are fairly cheap but I want to get it fully rigged and weighted down to see if I might want a 13 pitch.

Very interested in this thread

I've got a 87 20sf (which I believe may be a little longer then yours) and I currently top out 33mph at 5500-5600rpm. It's a painted stainless Yamaha prop 17p.

Out of curiosity what hole is your engine mounted in.

Nice looking boat.

The cavitation plate is about one inch above the boat bottom. 3rd hole but my transom was rebuilt to 25"ish so not factory specs. She is a 74 hull. If I had known where the motor would sit I would have built the transom higher than the 25 3/4" it is now.

If your running a Yamaha four stroke the 15 pitch Amita should get you a bit more speed/rpms but I was running a light load and 35mph at normal trim so we are pretty close I would think.
