I use one rudder all the time for going into and leaving the marina. I don't know that I would actively sail that way. 8)

Quick ? to anyone who may know... how do I size my pictures so you can actually see what going on when I upload the pic? I know you can click on the image to make it bigger but there's no way to zoom in on the pic I've opened unless you save the image to your device or screenshot it.

You can click the image and copy the raw image address. Then post that image (paste) into a post and use the [ img ] tags to display it.

For those curious, the GPS on my watch (Garmin 5X) claimed the top speed was 13.99 knots, then later 15 knots, though that was when the tide was changing, so might be with, against or neutral. That's 3 adult men, ice box full to the brim, with full water containers in the head and galley, and all the usual gumph on the boat.
I'm assuming that's WITH ballast. Not a bad speed. These boats do not get the brochure advertised speeds. Even without ballast, that would be close to expected speeds.

There's no way to adjust the pics I don't think.

Nope, ballast empty and not carrying the mast (still in the garden).

In fairness I simply took the engine to 6,000 rpm, though I suspect there was more throttle left. That I could redline the thing suggests the engine is running OK, and I held it there for 30 seconds to see if it would overheat, and it seems happy enough.

We've talked about the prop before and I think the one on there is pretty standard, but it did feel too low-geared, in that it was easy to rev it up to the red line on flat water. I guess that's better than a max top speed but no torque on rough water?

I still want to find a little backup engine that suits, then i'll be happy to cruise fair distances in the thing. It's not fast but if you give yourself a few hours or a day or two then even 5 mph will get you places :) For sure it's a different vibe from my speedboat but it's actually about as fast as my previous 19 ft deep V with a 90 hp 2-stroke. But vastly more space, comfort, style and safety, with drastically better fuel consumption!

Actually fuel was a pleasant surprise. Did around 22 nautical miles, both with and against the current as we hopped around various fishing spots over a 7 hour trip. Started with something less than a full tank, ended with 3/4 of a tank still, according to the gauge. That really is a drastic and welcome difference. :D

Glad you had a good outing! Really glad you got the motor running better.

Me too :)

What I'm trying to find now is a replacement hydraulic oil filler cap for the tilt. My one is pink from the sun (brittle?) and badly chewed up. It can be used but I'd really like to replace it, plus I have no spare and it looks easy to lose.

I have the shop manual but I'm still not sure of the part number. Just says "Oil hole cap" and not to re-use the O ring, which I obviously do because no spare parts...

Anyone know the actual part number so I can search for it?

Yep, may be under propped.

Looks like that motor WOT is 5500-6000

If you still had more juice in that throttle, it's probably too small of a prop.

+1 on the prop and RPM range. If you still have throttle at 6K on that engine then you are underpropped.

What I really really want is a little nesting dinghy.

Something like this:
