Not sure about the Yammie. I have an 18sf 1977. I am running a 2000 Johnson 2 stroke and get about 48-49 tops. Running a 19 pitch. Hope this helps a little.

On my sea trials in my soon to be 1970 20ft SF with a 2000 Johnson 150 we saw 49 on the GPS.

Sorry man, I wasn't paying attention to the names, I got you and Jetro mixed up. [img]/images/graemlins/crazy.gif[/img] (long day) I like the Yammies. Curious to see what kinda numbers you get outta her.

Alright I had my 20 out on my own for the first time today and she ran 40kts at 4900 RPM on GPS.
And she cruises easy at 3900 RPM at about 35kts.

I forgot to check the pitch on the prop, but I will soon enough.

I think I can get a little more out of her once I learn the correct trim.
