I've heard of checking the wake but have no idea of how far back the wash-wave-prop wash should converge.

OMC suggests starting at 1/2" toe in for V hull boats. Boston Whaler suggests 1/2" to 3/4" for their boats. I've read deeper V hulls need more toe in than flatter bottemed boats.
colobear in an old post (04-21-2008) stated that Karl the engine guy at EQ Marine said a little toe in is wanted.

I should have measured twice and posted once on this thread instead I remeasured after returning from work and found in my rush to measure and post before having to leave for work had given wrong measurement. The correct measurement on the Hunkydory is 24" at the props and 23" at the center of steering attachment ears, so the props are towed out. Always thought it steered good and hate to mess with what seems to be working, but now thinking maybe I do need to adjust.

This thread reminds me of my youthful days in Dad's hardware store and later years in Lowes prior to working a few years for Uncle Sam. When selling someone a new screen door, you have to ask... is it left or right hinged????? About 95% of the time, the person being asked the question, would, for what ever reason in the world, turn away from me and then act like they were swinging the screen door open and going thru the door at their home. They would turn back around and face me, and give me the answer.

I always wondered why they felt the need to turn around first? Maybe they wanted me to follow them inside and have a beer for helping them with the door??? Beer I do not know. Teeth Thumbs Up CoolSmile


Write this day down in history. I even took the time to run spell check on the above statement and ZERO mispelled words.... OK, so maybe I need to ask the administrators if spell check is broke...or toed in or out.

I really have a hard time believing that a half an inch (or so) makes a hoot of a difference on something that goes so slow (our boats) cruising in something with comparably little friction (water compared to tires on the pavement). Certainly there is a reason for the recommendation for toe in or toe out as there has to be some specification, tolerance, or guideline, because that is what engineers do. But if the boat tracks straight and you're happy with it, why mess around?

Jay, assuming the center of the steering attachment is forward, and the props are aft, wouldn't your measurements indicate a "toe-in" situation. I am thiniking that an imaginary pair of lines showing the forces from the steering attachments to the props would intersect forward of the engines. IMHO that looks to me like a toe-in setting.

I assure you, 5/8" made a huge difference in how our boat handled.
Twin engine inboard boats add toe in to their rudders too.

...In the automotive world, toe-in means that the front of the tires are closer than the back of the tires. In a boat, the thrust lines are convergent. There is not an automotive counterpart.


You know, maybe there is. The front tires control the vehicles direction and need toe for stability. The (twin) outboards control the boats direction and use toe in for the same reason.
I 'spose the no feedback steering (with it's clutches 'n stuff) on our boat could be more sensitive than hydraulic steering systems, for instance.

Jay, now there is a real health nemesis. Twisted Evil We can blame it on Edison and followers. If humans were meant to work nights, they would be born with headlights Shocked

....and it would be toe in, right?

Yes, Harvey, I agree the set up is toe in even if the props are tow out. Laughing Laughing

I set the engines at 1/2" toe in and took it out yesterday for a test. Ran great but I have Morse steering, not the NFB steering, and I have bad steering torgue to the right so I can't tell if the toe-in is correct or not. I asked the dealer where I bought it to check the fins on the skeg and he said he adjusted them but I think I need more. Even at idle, when I take my hands off the wheel it creeps pretty rapidly to the right.
