Charlie: The MOD rules require the use of the Y80 gearbox or the 302 gearbox in the Yamato MOD 350 class. You can use aftermarket gears but they must be the same 14/16 gear ratio that came with the gearbox. The R and S dimensions are critical but other than that you can change the shape without problems...

There's an optimum angle of attack, usually quoted at 3-4 degrees, for best performance. Go below that you get increased drag from more of the boat touching the water, exceed it and you are pushing more air, which causes drag.

There is absolutely more of the boat in the water than just...

I have a tech question when you mod guys Tuen the stock Y80 to a mod. What Lower unit do y’all use? Or do you change the gears in the stock lower unit?

Will consider any offers

Great stuff, thank you for your input. I had not thought about directional stability which makes sense being that there is no part of the boat other than the prop in the water on a long straight. I was paying attention to the attitudes of the different hydro classes and noticed that the clear winners...

Hey Herb, chair is ours, left it over there during the 300 prop draw.

I agree with Dane, this is a solid trailer that Mike built. Needs nothing, load your gear and go race.

Lots of interest so far...

Thanks for another good time, good fellowship and GREAT RACING! Someone left a purple chair at my trailer, it will come to Tabor with me, if you can tell me what color it is its yours.I would add that this chair is much nicer than any of mine, so the description better be good!

BUMP.........

Call John Korbus. He sells slotted aluminum plates that slide up and down to accommodate CSH and 300ssH. Simply loosen 4 or 5 bolts, slide up the 2 AL plates, insert your spacer block, and re-tighten the bolts. Works very well.

Vortex generators serve the purpose of delaying airflow detachment from a surface (stall). You'll often see them on STOL aircraft as it helps with high angle of attack flight regimes, or to increase flap effectiveness, etc. Unfortunately, they also create drag, so speed performance can be affected....

Okie doke, thanks guys.

My main concern was if the arrangement would be strong enough to begin with (and I was hoping so, as I don't want to have to replace the entire transom). The 3/16" plates will be helpful to increase the thickness so I won't need a wood spacer to tighten my...

Thank you for the compliment. I put alot of thought into building it.

Someone left a shirt on my Trailer near the registration table at Lockhaven. I would like to try and get it back to the owner. Please PM me and Identify.
