Show your boat not sailing

PYI usually wants the old Max prop as a "trade-in" and they knock some of the price off. Jerome let me keep mine. It works well still. A bit ugly and used for sure. I might Craigslist it after a bit of polishing...

Mostly in Bass Strait and the Tasman Sea,

You, sir, have my utmost respect.

I spent a week in that area in a small (2,500 ton) and narrow (L/B ~ 8) Navy ship. Seas were constantly 15 m. For the entire week no one was allowed on deck and the cooks could only make scrambled eggs and sandwiches.

I wish you fair winds.

Got enough sheer sweep there Butch?

The four blade is a nice upgrade from the three blade. It has a bit more oomph and seems to be smoother.

Beer Mayhem - please please please post your judgements on the 4 blade vs 3 blade as soon as you have some motoring time in. I'm very curious to see if there is much difference at this size range. I've installed quite a few 3 blades, really like them

I'm curious about the 4-blade as well, and would be interested in the logic behind it for a sailboat.

What's the F-86 doing in the background? (We had several squadrons of those on my father's Air Force base in Germany a few years after the end of WW2.)

I vaguely recall the 1958 movie, "The Hunters" about the air war in Korea, which featured the F-86. I would have 9 or 10 when I saw it. Very exciting, although I did not understand the mushy parts.

That Sabre look a lot like one of the Golden Hawks. They were the RCAF demonstration team BITD.

Why don't you all list the types of boats you are showing to the masses?

Great looing boat, Insolent.

It'd be lovely to hear more about her ... if you feel like telling.

On the hard for a repower. Just what we wanted to do before leaving for the winter. Lucky for us Yanmar came through with engines and saildrives. Out with the Volvo's.

Splashed my boat yesterday.
Sadly, PYI was off on the pitch. I am waaaaay under pitch. The motor just rockets to redline almost like being in idle. At my cruising RPM (2400~), I was only able to get 6.8 knots. I was at 7.8 with the three blade. So I'll dive on the prop and bump it up. I am currently at 22°. Per Jerome, every 2° drops the RPM by 250. He is thinking maybe bumping it to 26°.
There is thought about overpitching so you load the motor more and make it work...
I will say the prop is super smooth. I'll report back after I adjust the pitch.

Be very careful about over pitching. You must know just where engine overloads & not pass that RPM. Yanmar strongly against this concept.

Exhaust temp always tells the truth

when in doubt hire an engineer
