If we are talking about the length to width ratio of each sponson, the answer is the same: it depends on what you're optimizing for and you'll have to decide on your trade-offs anyway.

Technically speaking, most of the boats discussed here are tunnel hulls. The terminology gets debated a lot, but in a tunnel hull the sponsons affect each other hydrodynamically (because they are...

If you think your oil is going to eat your engine, you should change it. Downtime is actually safer in this case since when you're running the motor oil circulates and is at higher temperature.

Don't think it's that easy. Underwater housings have no space for cable jacks, so you'll need something custom anyway. And water pressure gets very high very quickly as you go down, your standard...

It does have a provision, but if you attach a cable you lose the ability to put the camera into water :-/

I understand why raising the motor can be beneficial. I don't understand how you can have both increased speed at the same rpm and increased calculated slip at the same time.

How does that work? Calculated slip is a simple formula, given the same motor and the same prop it's just a function of speed at the given rpm. More speed for the same rpm implies less calculated...

Yes. Look up what your outboard specifies for CCA and then check what your battery can provide -- it's not just the group size, compare the specs for MCA/CCA. Deep cycle batteries typically have less...

Outboards tend to run with coolant temperatures of 130-160F, but that doesn't mean that some parts of them cannot get hotter. On the other hand, there's a whole bunch of plastic under the cowl, so it...

I use deep cycle AGM batteries for both cranking and house. The catch is they have to be able to provide sufficient MCA/CCA which means they're big. I'm fine with that.

I am not sure what are you going to gain. You still need to run corroding wires for power to every little sensor. Yes, you got rid of data wires, but at cost and with limited applicability. How would...

Not at all, that's not what I'm saying. Obviously you cannot plug an SMD7 directly into a engine harness, they are not compatible.

The first part is correct, the second is not.

An SMD7 does display engine data that comes to it through the NMEA2000 network. But any other NMEA2000 MFD can not do the same thing.

NMEA2000 is a...

It won't hurt the GPS, but, as mentioned above, with the wrong setting the charge indicator will not be correct.

NMEA2000 has the big advantage of being simpler and cheaper. "Simpler" also implies being more robust.

The problem with NMEA2K is limited bandwidth which is an issue with things like radar --...

So the tide was outgoing and you were in a waves against tide situation, not the best time. You also had 15-20 mph wind from SSE which didn't help.
