Since it's January, it's time to over-analyze some trivial boat decisions.

To any of the very few of us out there that still have cable steering...

Looking to upgrade to a new 3-spoke wheel with a knob. Current wheel is 15" destroyer. Boat is only a 17ft, so I think the 13 would look better based on the newer boats coming out (all with hydraulic steering though).

My question is, has anyone gone from a 15" to a 13.5" on a boat with cable steering?

Concerns:
-Would a 13 be a b**** to operate? (my wife drives the boat sometimes)
-I've heard a few people mention that installing a knob sometimes puts the jewels in jeopardy.

Seems like my options with a product like Schmitt are 13.5 and 15.5. Edson has a 14.5 that could be a good compromise, but it's not cheap.

Just trying to get some input before just buying both sizes and returning the one that doesn't work out.

from a purely rotational standpoint it is 13.5 percent reduction in diameter . Obviously it will have to rotate more to turn the same. I would expect any friction in the system to be amplified as well due to the reduced diameter. Can your wife stand 10-15% more umph (that's a technical term) ?

my .02 cents.

That's also an involved calculation. There is a 2.4% increase in complaints per 1% increase in required umph squared. This increase holds the plotted curve until it drops off at the point where she goes in the drink.

Dude, how pimp is your boat that the best thing you have to spend time and/or money on is the helm wheel?? I like a small wheel because I have a small boat, and it takes up less space in the walk-thrus.

Oh I have more to spend time/money on, but I know the answers to most of the other ones. The two potential answers to most other broken stuff replacement questions are A) Nah it's fine or B) cheapest thing possible.

Also, my helm doesn't tilt. hic

I just put a new GEM wheel with a knob on my skiff and it is a very good quality wheel and not that expensive.

I had a 13" wheel on my 17' skiff with cable steering. It was the perfect fit and especially for that particular console. I wouldn't have wanted anything bigger. I also did not have a knob but it needed it.

My current skiff has the 15" wheel, (it tilts), and I added the aftermarket Edson knob so I could place it where I wanted. Plus vmarine makes AWESOME art inserts for the Edson (& gem lux)!

There is nothing 'obvious' about that relationship, to me. One turn is one turn, regardless of diameter. The only thing that increase is effort required, if not power assisted. Your hand will travel farther in one revolution of the larger wheel, but it will produce the same rotation of the shaft as the smaller wheel.

Yes yes but you always opt for a quarter-turn with a screwdriver over a breaker bar when you have the choice. Both are a quarter turn. The question at hand is whether anyone here bought a screwdriver and regretted it.

Looks like we have one skiff owner in the smaller wheel camp.
